No dial tone through SPA112 ATA box

I can't get my analgue phone to work thru the Cisco SPA112 ATA box - problem has been ongoing for 2.5 months now.
My ISP can access the ATA through their network and assure me everything is configured and working correctly.
My wireless (wimax) internet connection works fine.
My phone used to work thru the ATA box, but I have had no dialling tone since it suddenly stopped working in early Oct. 2014.
I've tested my phone & cables on a BT land line - cables and phone all work on a land line.
My ISP provided a replacement ATA box - I still get the same problem of no dial tone on my phone via the ATA.
I've also taken my ATA box & phone setup to my parents' house to test setup and equipment on mains power & their land line broadband connection - I still could not get a dialling tone.
My ISP is adamant the problem is with my phone and/or home power system, and not with the VOIP set they are providing me.
(NOTE: I live off grid - the house power is provided from a 12 V battery bank through a 230V true sine wave inverter.)
I've just bought a new mains powered Binatone phone & I still get no dialling tone, nor can I make or receive calls.
Since my ISP has given up on me and blaming my home power supply and/or phones, can someone please advise me if the problem might lie with:
1) My phones
2) the SPA112 ATA box
3) My VOIP configuration
The problem has become exasperating - and I need a working phone for reliable communications. Going back to BT is NOT an option since I still have to wait an unspecified period of time to get a broadband service via BT or any other provider.
Any suggestions would be appreciated.

One easy way to test if your device is working is to register for a free voip service. Here is a list http://www.voip-info.org/wiki/view/Free+VoIP+Networks .
That will allow you to test with a different provider and credentials. be aware the free service is frequently limited to making calls on that providers network, but it should allow you to make a call.
You can update the firmware on your ATA to the latest. Download the latest here https://software.cisco.com/portal/pub/download/portal/select.html?&mdfid=283998771&flowid=30521&softwareid=282463187
What does it say for the status of line 1 on the information page of the GUI? registered/failed? if it says registered, you should get dial tone. if it has failed, your credentials or network connection may be incorrectly configured.
You can test your analog phone set by finding a friend who has an analog phone line and taking it there, or
plug your analog phone into line 1 and hit 4 stars ( **** ) you should get a voice menu. Hit 110 to have it read the IP address of the device. This will let you know if the phone is working (at least basically)
If you are still under warranty, you could call into the small business support center, we could try a couple things.
We could use your credentials on one of our test devices here to see if your provider settings work. If not we can help you follow up with your provider.

Canon PIXMA MX850 fax and FiOS - "No Dial Tone"

I have a new multi-function printer and FiOS Internet, Phone and TV. My old analog phones work just fine and get a dial tone through all the phone jacks, but the fax doesn't recognize the dial tone. I've read about micro-filter and splitting devices for DSL connections; will they help with my problem?
Hope someone has advice!
Thanks!

On your vioce phones, do you get a dial tone the exact second you pick up the phone, or is there a delay, like a incoming voicemail msg that needs to be listened to? I'm willing to bet that your phone system tells you you have unheard voicemail messages by adding a delay before voicemail, and that will affect your fax machine. Clear your voicemail and try again.

Call manager: outside dial tone

Hy all,
i want to change the outside dial tone from the current 0 to 9.
I have "0!"route pattern for routing offnet calls. I canghed it to "9!" but i had no tone on pressing 9.
Can you help me?

Hi Marco,
Check your 9@ Route Patterns for this setting;

4630 dial tone detection fail

Getting a Dial Tone Detection fail on my 4630. The line has a dial tone through a phone. Anyone ever see this before?

Hi @PTrietschChaney,
Welcome to the HP Forums!
I understand that you are getting a dial tone detection fail with your HP Officejet 4630. I am happy to look into this issue for you!
For further assistance, I have a few questions for you:
Is your phone service analog or digital? Analog. Digital. What’s the Difference?
If the phone service is analog, please see this guide, Cannot Send or Receive Faxes. If the phone service is digital, then see this guide, How to connect your HP Fax Device to an ISDN, ADSL, PBX, or VoIP line. HP fax devices are designed to work with traditional analog phone services. They are not designed to work with digital phone services such as ADSL, PBX, ISDN, or VoIP. While HP fax products are not supported on these types of lines, they might work given appropriate setup and equipment.
For future reference, here is your printer's user guide.

SPA112 ATA CallerID issue causes device to hang

Hi Everyone,
I just thought I would share my experience with an issue setting up my SPA112 with voip.ms. Although I still do not have a solution, the Cisco technical support has been very helpful allowing us to track down and debug the issue.
Hardware: SPA112
Firmware: 1.1.0 (011) Feb 10 2012
ITSP: voip.ms
Service Number: SR 622048069
issue:
Inbound calls through the DID cause SPA112 to ring once. The ATA immediately drops the call and loses ethernet. The device is unresponseive until it is rebooted. If the device is not rebooted, there is no dial tone on the headset connected to the ATA.
The device hangs when I called it from my cell phone or from skype dialed to a phone number. The device works when I call it from another voip extension or through any softphone connected to my asterisk PBX on my local network.
The device works fine when the cisco representiative called from his companies voip phone and his companies analoge non-voip line.
We've tested the device with and without a NAT with the SIP connected directly to voip.ms (no asterisk server running).
After setting up some debug equipement, the cisco representative was able to determine that the cause of the hangup was related to incoming callerid errors. We are still invegstiating the issue and I will keep you posted as I get more information.
The device only seems to fail when it recieves calls from some numbers. I do not know which incoming numbers cause this issue at this point.
work around:
1) At this time the PAP2T, which uses the exact same settings as the SPA112, works without any problems.
2) We are also looking into alternatives, such as disabling the CallerID on the SPA112 until the firmware is upgraded or overriding the caller ID info using my asterisk server.
Justin

I recently purchased a SPA112 myself & I've discovered a very similar issue.
Inbound calls from my work (VoIP system) cause SPA112 to ring once. The ATA immediately drops the call and loses ethernet/internet. The device is unresponseive until it is rebooted. If the device is not rebooted, there is no dial tone on the handsets connected to the ATA.
I've updated my firmware to
Firmware for SPA112 and SPA122, Version 1.2.1(004)
Release Date: 15 Aug 2012 Release: 1.2.1(004)

Getting the dial tone on my landline using a DECT ...

This issue has been ongoing since April 2012. If I use my Panasonic DECT phone (bought in 2006) to make or receive a call, the BB connection drops within 5 secs (Home Hub 2.0). I had a Voyager 220V for 6 years working alongside this DECT phone and all was well.
I had to call BT Faults in April because suddenly my BB service kept dropping out up to 6 times every half hour. (unrelated to the phone at that stage). BT Faults Level 1 (India) said the Voyager needed had come to the end of it's life and needed replacing with a Home Hub 2.0. They also said there was a software issue at their end & it would be sorted within 24 hours!!!. The replacement Hub worked with my DECT phone for less than a week before I noticed whenever I made or received a call the BB dropped out after 10 seconds.
I called BT Faults about the issue of BB dropping out when the phone was used, but it went on for weeks with BT not getting to the nub of the problem. They did their usual tests and in July they sent an engineer who swapped the hub over, ripped out the existing ADSL box, put in a new SSFB box (no filters required), tested and all was well for..... 10 days. Then the old problem returned. I checked with my phone company about compatibility issues, but they were unable to help. (after all the phone had worked for 6 years alongside the old router).
I wrote to BT complaints and in Aug 2012, they sent yet another engineer who this time ripped out the existing internal cabling just outside the front door of the property (star wiring) and put a direct line in from outside, telling me that this should rectify the problem!!! Another Home Hub 2.0 was tested and appeared to work compatibly with my DECT phone. Within 3weeks the old problem had come back. BB drops whenever I get a dial tone or receive a call.
I've tried swapping over locations for the Hub and phone (at least 5' away from each other), swapped over power sockets, isolated all electrical devices using the same power socket, connected the Hub and the phone only to a different power socket. I'm fast running out of options. BT Level 2 Faults will call me on Mon 24 if nothing has changed they want to send another engineer who this time will charge £110 no doubt & they still can't get to the bottom of the issue.
If you've been through something similar and can offer suggestions, anyone please?
Wits end!

Internal modem not detecting dial tone

I have an iMac G3 CRT 333MHz (Lime) which is having trouble connecting to my dial-up internet connection. I am fearing that my internal modem is 'burnt out', and am wondering if anyone out there has any additional troubleshooting tips, or any advice on purchasing a new external modem.
The trouble started after a lightning storm, which also disrupted internet connections for my roommate's PC (I don't know exactly how he fixed his, but he is connected via a DSL modem and says he simply restored some modem drivers). I have noticed, however, that he removed his 56k modem...
When I attempt to dial-up from my Mac, I get a message stating "Modem did not detect a dial-tone or the line is currently in use..." I have checked and double checked that the phone line does indeed have a dial tone, and tried connecting through through various outlets throughout the house. I've disconnected all other phone hardware (except the DSL filters) and reached the same result.
I am currently running OSX (10.3.9), and also attempted to dial out after restarting in 9.2.2. (Same result). After that, I dug out my install CD and reinstalled 10.3 (same result)
From each OS, I've run system profiler and recieved no unusual information about the internal modem. The computer definitely senses that I HAVE a modem (Apple Vsn 0007-1,9/2/1998 v.90) That modem simply can't seem to detect the dial tone.
I have also confirmed my modem settings, tried checking and unchecking the 'sound' and 'wait for dial tone' boxes. My internet provider is NetZero, so I have attempted to dial in using their software, as well as directly through Internet Connect. All attempts return the same message. (and the NetZero account is still active, I have accessed it from two separate computers).
Any thoughts out there if there are any further settings or or software/OS variations I should try? Or are my suspicions valid that the storm somehow fried the modem (there were no power interruptions during the storm... only modem troubles)
My next step might be to find an external modem. I've not seen any Mac-compatible 56k modems in stores. There is a Apple USB Modem in the Apple store, but it requires OS 10.4.3 and a computer 'without a built-in modem', so I don't think that will help me. I've also considered using Airport to share my roommate's DSL connection, but I believe that my model of iMac is not airport compatible...
I also have a dead iMac in the closet (DV model) with a blown ethernet port, broken fan, and damaged hard drive. I'm not above cannibalizing either machine to get the other working until I can afford a new G5...
Any thoughts, suggestions, or shared experiences would be greatly appreciated!!

The only thing I can think of is to go in to the modem settings and choose ignore dial-tone. That way even if it's not getting a good tone the iMac will continue to try to connect. This is also important if you have a voice mail system that varies the dialling tone whne you have a message as I know that stops my father's Win98 box connecting to the Internet unless the equivalent option is checked.
You can update your email address to a current one here. If the Apple ID (i.e. the one you login with) is old don't worry that's pretty irrelevant.

Strange dial tone

Hello, just noticed recently when I pick up the phone I have a strange dial tone.
It sounds like the normal one but then the tone lowers, then comes back up, then down again. Kind of like a siren on a police car/ambulance only not as loud.
Any idea what could cause it, there is only one socket in the house, and we only bought a new phone back in October, broadband speeds all seem fine and I have removed the sky box to also see but its still there.
We have an overhead line and some quite heavy rain a few nights back, was wondering had the connection box on the side of the house got damp and would I be charged for someone to come and look at it?
Many thanks

Hi,
I've been researching this issue on the internet and came across this post as it sounds exactly what has happened to us.
On bank holiday monday, we set our phone on divert #21# as usual when we spend a day out. We came home only to find we had a strange ring tone (sounds like a siren) and we can't make any outgoing call, nor can we switch off the divert. Even though we can't make any outgoing calls, the divert still works so we can take calls on our mobile.
It is very strange. We have reported the fault with BT who have checked the line remotely and say it looks fine. We have test our internal equipment, and also tested a phone through the emergency socket which runs into the master socket. We still get the same ring tone.
BT.com/faults suggest now that it may be something not right near our home.
Did anyone on this post get their issue resolved? What was the issue?
Many thanks!

I have a wireless home phone connect device. Can call out on it when dial tone present, but most times cannot receive calls since purchase. Anyone else having a problem with their home connect device?

Have had Wireless Home Phone connect device refreshed and updated three times since I purchased it in September 2014. Last tech I worked with on it initialized an NRB to check the network. I checked the location of the tower, which is less than one mile up the hill with clear line of site. The device always has two antennas on it. The device is great when it does work, but most of the time it rings three times and then jumps to an automated message saying the person I am calling is not available. I've actually gone up there several times to try an fix the device, but always end up calling a Verizon tech who has me unplug it, pull the battery, and they do some network stuff and then we turn it back on and it works. After the last time on 10/02/14, I called it and got the message. I drove up there, 100 miles one way, and called it while standing in the room. Got the same message. I picked up the phone, heard a dial tone and dialed my phone and it range through. I hung that phone connected to the device and call it using my cell phone. It rang through. I went home and tried to call it the next day. Again it did not ring through and I got the message after three rings. I call another phone at the facility and had them call me on my mom's phone and it is fixed it again. The fix last for a day or two and then it's broken again, like it is today. If it's a network problem then it must be fairly close to the area because no matter what we do it fails again. So much for the 99.98% reliable. This thing is a piece of junk!
I purchased this device and put it on my plan so that my mother who we placed in a home at 96 years old would have a phone connection that she could use and wouldn't flip her out. My family and her family has not been able to faithfully connect with her at this critical time in her life. I am giving Verizon 10 more days to figure this out and then I am going to ask for a total refund not to mention how much time and travel I have put into this piece of junk. Either the home connect transceiver is broken or the network is broken. Why should I pay close to $70 for a service that has not worked more than several days out of 35 days? Also I have spent close to three hours on the phone with decent technical people, but it's my time. I should send Verizon a bill for every time I have gone up there to fix this device as well.
What perplexes me is that a regular cell phone would have sufficed, but because Verizon has to have a data connection that is not available on a regular phone and it was going to cost me $30/month, I decided to go with the home connect. Seemed like a nice solution for an older person who would have a hard time using a cell phone and keeping it charged. Plus after all the fees for getting it connected, it only cost $20/month. That would be a pretty good thing, IF IT WORKED....... The other thing that irks me is, why do I have to pay for a data connection when the cell phone Verizon originally provided can't even access the network. What ever happened to adding a phone line for $10 bucks\ month? All I wanted was a simple phone. She would not be able to use anything more complex and all she needs is a phone line period.
I have no problem paying for something that works and does what it should, but this is ridiculousness. The MTF on this device is somewhere around 1 to 2 days. Out of 365 days that's about a 96.5% failure rate....... Want my advice? Get ride of this device. It sucks and it's bad marketing.

jsavage9621,
It pains me to hear about your experience with the Home Phone Connect. This device usually works seamlessly and is a great alternative to a landline phone. It sounds like we've done our fair share of work on your account here. I'm going to go ahead and send you a Private Message so that we can access your account and review any open tickets for you. I look forward to speaking with you.

New Broadband - No Dial tone - Line Test shows no ...

Hi,
I was wondering if anyone can help me before i start pulling my hair out!....
I have recently attempted to set up my new broadband and phone.
My activation date was 4 days ago and ever since ive been on the phone to customer service trying to work out what the problem is.
Summary of problem:
my phone line has no dial tone at all. On my day of activation, the manager from the office below my flat came to tell me his phone lines had been cut off. After this, he tried to set his line back up and i recieved an email to tell me someone was requesting to take over my line. So i phoned BT and they cancelled off this request and assured me they had set up the line to the right address and not the offices below me. I was told it was an internet problem and that i should wait to midnight until my activation is complete (although i had already recied two emails to tell me this was complete).
I waited a further 48 hours until today - Phoned up, explained the problem again went through line tests/broadband tests and was told that everything was fine, it should be working. It must be a connection problem between my router and device. Ive tried several devicces (laptop, phone, ipday, tv etc) and none of which work. They connect to the router but say the router is not connected to internet.
My router has solid orange light with flashing red "b".
I dont know what to do next?
Help please!!
Thanks,
Arlene

No dial tone for the second time now

Hi guys,
Back in late November 2013 I discovered that the phone was not working correctly that being no dial tone and a faint outside crackling noise coming through, I couldn't call out or receive calls however when I called my phone the line rang fine but it was not coming through the headset, My broadband was still working perfectly fine so I instantly thought it was the headset and ordered a new one only to discover that it in fact wasn’t the problem at all. I began to call BT to report the fault and was directed straight to an Indian call centre the guy when through normal line testing faults only to come back with no faults found I told him that on my mobile my house is ringing but none of my headsets old or new was physically ringing we then went on to do the master test socket test and again same problem. After that he arranged an engineer to come out to have a look and was told the usual ''you may be charged if you have caused the fault'' blah blah now into December and I finally get an engineer out to have a look the engineer when on to say that whoever initially installed the face plate put a faulty one and that was the problem but if that was the case how had I been able to use my house phone perfectly fine prior to this problem? I asked the engineer if I would be charged for this call out and his said NO as it was not my fault, all things fixed and working.
My January bill came and what do I see £179 bill I look at the bill to see I’ve been charged for the engineer callout, furious I call BT in which this time I’m directed to English speaking people at last. I explain all of the above to the operator and go on to tell them I was told there would be no charge so they check the engineer report and then they tell me the engineer reported that the faceplate was damaged, I’m then question by the operator and asked how I had damaged the faceplate I told him what the engineer told me and that my master socket is up high on my window seal out of reach of my son so there was no way he damaged it, they told me they would look into for me and get in contact within 5 days. 5 days pass and I get the call saying sorry for mistake your money will be back in your account in 3 days well that’s great news.
Now I’m having the very same problem with my phone line no dial tone slight crackling sound but this time when I ring from my mobile may house phone rings fine but when I answer it up it continues to ring even though I’ve pressed the accept button I also cannot decline the call from the headset it really frustrating, I’ve tried to get though to BT but the queue times are just ridiculous even tried the call back feature and yet 3 hours later still nothing I’m not going to pay for a service I’m not receiving and I’m most definitely not going to pay engineer charges only to be refunded 10 days later a complete waste of time. I need my phone line fixed please can someone help me out here and give me some advice.
Many Thanks
Mike

You need to raise this on the Business Forum, this one is for residential customers.
You can click the white star next to this message if you think it was helpful.

My iphone won't ring for me to answer or when I send a call, no dial tone.

when I get phone call, I miss it because it doesn't ring and also when I make a call, there is no dial tone.

Try a reset. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. After the phone starts back up, see if it will work. Also, I have never witnessed a cell phone give you a dial tone. You dial a number, then press send for the call to go through.

Fax/no dial tone

Hi
I have been trying to send a fax for the first time on my G4.
I have followed the help that is available on the Mac website and have even called technical support who didn't do very much except e-mail me some information available on the suport website!
I am connected to the internet (broadband) via a usb modem which only reads digital signals, and the connection is running through ethernet adaptor in my network settings.
I have a broadband filter supplying the modem at the phone socket which also has a separate branch for my phone line.
I got a regular phone cable (one end fits into the phone socket and has smaller fitting on the other end) and I first tried sending a fax via the phone branch on my filter and the internal modem slot on my Mac and after the system tried to send the fax, it told me that there was no dial tone.
Next, i checked that the phone cable worked (which it did) and tried to go direct between the internal modem slot and the phone socket with the same result as before. I only have one phone socket and no answer machine so I dont think anything is interrupting the analouge signal.
Has this happen to anybody else? Can anyone help me?
It would really help me ouy as I dont really know what else I can do and technical support hasn't really helped!
Thanks

From Free Dialup.net.UK...
http://www.free-dialup.net/free-dialup-uk-articles/dial-up-modems.html
"Q: Why my modem is not getting Dial Tone?
6. Many voicemail systems use a "stutter" dial tone or beeping when you pick up the phone to indicate that you have voicemail waiting. These unexpected sounds can make the modem think there is no dial tone.
7. In extreme case, your modem may not be designed for the phone system in the country in which you are trying to use it."
Acoustic couplers should work when all else has failed...
http://www.roadnews.com/html/Articles/a31.htm
You can also run into problems with dial tones overseas. Your computer may not recognize the dial tone of the country you are in as a "dial tone." Depending on the modem software you are using, you might need to put a check in the Ignore Dialtone checkbox in your modem software setup window.
What about digital telephone systems?
Modems communicate using analog or sound signals while many new telephone systems use digital signal processing. Digital systems are unable to process analog signals, making it impossible for modems to communicate.
Seems that there very well might be some diff in the Modems between Switzerland and UK...

Port Problem in ATA Box

Hi there,
I'm having a problem with one port in an ATA Box, I can receive calls properly from any internal and external phone but when I try to call from the phone connected to port 2 in my ATA I get a busy line signal but the line is available. The problem occurs just in port 2 because when I try the same from port 1 it works well. I've configured the ATA from the beggining and also copied the configuration from another that is working and still same. Any idea?
Thanks a lot for your help!

Hello Fedex/pharden,
What pharden said is correct, to be more accurate it is documented here:
ATA 186 3.2 Admin guide
http://www.cisco.com/en/US/docs/voice_ip_comm/cata/186_188/3_0/english/administration/guide/sccp/sccpaape.html#wp1061348
The problem:
So basically when the ATA186 is configured on CCM to use G729 it can only support one g729 call, and the other port will use G711 always no matter what we do (that is due to the ATA DSP capabilities), what we can tweak is which port will be affected by this behavior by changing the LBRcodec parameter, clearly this will not solve the problem - only change which port will be affected - but at least it will help you out to understand the situation better.
Now why the ATA is using G729? which is basically what is causing this due to the ATA limitation explained above. There might be a diferent number of reasons, maybe because the ATA is on a remote site where the bandwidth savings of the G729 codec are benign but in the other hand causes this problem.
The Solution:
There are 2 possible:
1- Make sure that the ATA devices have a hardware XCODER available on the Media Resource Group List (as of now MRGL), the fact that you get a fast busy is due to a codec issue (the second port supports only G711 and the gateway probably only supports G729 or the Region configuration says that between the ATA and the GW only G729 should be used).
So if a transcoder is available it will be use to XCODE and the second port will work as well, make sure to do update/reset on the second port once you assign the proper MRGL.
2- The solution is to use G711ulaw on the second port always (once again there might be a reason to use G729 on both ports of the ATA and if you are not willing to use G711 on the second port then don't bother reading the rest of the post), how do we change this?
As you probably know each port shows up on CCM as different devices (different MAC addresses) when you do a search for devices.
Look at the Device Pool assigned to both ports, most likely they are under the same Device Pool (as of now referred as DP), this DP has a region assigned (on the DP config on CCM), the region pretty much says wich codec will be used, between devices on this region and devices on another region.
Look for the Voice Gateway on CCM where the calls are being sent out to the PSTN, then look for the DP, take note of that DP, look for the config of that DP and check the region assigned to that DP.
Now its time to compare, the region of the DP where the second port is assigned and the region of the DP where the Gateway is assigned.
You will need to make sure that the regions talk one to the other G711, if they don't - which I bet is the current situation - change it so that both talk G711 one to another.
Keep in mind that this will affect all the devices on that DP (because the same region is assigned to this DP) and probably some other IP phones are on this same DP, so if you do not want to affect the other devices, create a new DP with a new region and ensure that the new region and the region of the GW talk G711.
If the Voice gateway is MGCP you should be done by now and calls from the second port will work just fine.
If the Gateway is H323 or SIP you will need to define the inbound voip dial peer, and add a voice-class so that it supports G711 besides G729
Both ATA ports on CCM should be assigned to
device is assigned on CCM to a Device Pool
Hope that this helps!
