Ata 186 second port problem

Hello
There are a atas186 who was registered to a CUCM version 6.1,the call manager was migrated to version 8.6 but now the second por when a call is answered immediately when give a fast busy tone, the first port works perfect, and i have changed many parameters and did a factory reset without success.
S/W Version 3.02.04(090202A)
App Load ID ATA030204SCCP090202A
Thanks.

Your ata´s place calls across the wan?
If yes, the the ata 186, only support one port in g729 codec the port 0, the second port works only in g711 codec so try to configure a region to place calls only in g711 codec across the wan and problem solve
i hope it helps...

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!

ATA187 Second Line Problem

Hi,
I have a customer with the following problem:
The second port of their ATA187s are constantly trying to register and establishes UDP connections with the site firewall. Eventually this exceeds the max connections on the F/W and results in a major site problem. The customer has overcome this by assigning a DN on the 2nd line. However, this creates a 2nd device in effect. The customer is migarting soon from CUCM ver 8.5.1 to the latest version 10.
My questions: is there a way to disable the second port on the ata187? I know this is possible on the 186/188's but I don't think we can on the 187s?
Will moving to 10.x help this situation? They need to know because, they will have to buy twice the number of essential licenses just to fix this annoying problem.
They have upgraded the ata187s to the latest firmware.
Many thanks.

Unfortunately 187's does not support disabling of 2nd line. Moving to 10.X, customer will have to use the same solution as they are using right now.

ATA 186 - HP FAX Accessory 300

We have an ATA 186 which we want to connect to our MFD. When we connect the device to the MFD and ring the port the MFD will not answer the call. If we connect to a VG224 the MFD detects ring ok and answers the call. If we plug a POT into the ATA the phone rings ok so we know there is an issue between the ring voltage of the ATA 40v and what the HP MDF is expecting. The MFD is a Q7519A but I can't find any info on the ring voltage required. Any Suggestions?

This is my suggestion:
- check if the telephony cable has only 1 couple of wire (tip and ring only); in the past I had some problems with cable with 4 wire (2 couple); the ATA had a strange behavior;
- try to connect an analog telephone to the ATA186 and verify if it works;
- if the problem persists probably the ATA has an hardware fault;
- try with a different ATA;
Best Regards.

Cisco ATA 186 Issue

Hi there,
I configured both ports of a Cisco ATA 186 connected to CM 4.1. On both ports I've configured Analogue telephones. The telephone working on the 1st port works fine, but the phone connected to 2nd port will ring once and the connection is broken. If I change the ports then, the phone on the first port will work fine but the phone connected to the 2nd port got the same issue.
I hope someone can help me sort out this issue.
Thanks.

Hi Sana,
Just a thought here, but the second port of an ATA only supports g.711;
Have a look at these two good posts that relate to this type of issue;

1751-V & ATA-186 Incompatibility

Hi There,
I have a VoIP network, of two Cisco 1750-4V, two Cisco 1751-V multiservice routers and two ATA-186 voice gateways.
The communication between any 1750-4V and ATA-186 devices is flawless in both directions. However, when we try to make a call from 1751-V (FXO or FXS port) to the ATA-186, it's impossible. The communication from any ATA-186 to any 1750-4V, the other ATA-186, and any 1751-V (FXO or FXS port) is flawless.
I don't know if a newer version of ATA-186 flash ROM (actually there is 2.07 version) will solve this problem?
I will appreciate any comments.
Regards,
Igor Sotelo.

Thank you for the information.
We don't use a gatekeeper, and I have the following configuration on both 1751-V (the configuration is the same on the 1750-4V's):
dial-peer voice 5000 voip
.destination-pattern 500.
.session target ipv4:x.y.z.w
where x.y.z.w is a external valid IP address.
On the ATA-186 we have configured:
static IP: x.y.z.w
static net mask: 255.255.255.240
UID0: 5000
UID1: 5001
and static route: x.y.z.w1
I can ping the devices from the 1751-V without problems, and also call the 1751-V from the ATA. However, I can't call the ATA from the 1751-V.
Do you have idea, of what can be wrong?
Regards,
Igor Sotelo.

Port Problem, cant Recieve Mail

Hi
Just recently my mail has stopted working due to a port problem. By my inbox i get a small icon which is a triangle with an explanation mark in. When i click it the first message i get is:
*Connection Failed*
+There may be a problem with the mail server or network. Check the settings for account "POP Account" or try again.+
+The server error encountered was: The connection to host mail.kahane.co.uk on port 110 failed.+
Then it willl give me a chice to go offline or online, ill click online and the icon is still there so i click the icon again and the second message i get is:
Alert
+There may be a problem with the mail server or network. Check the settings for account "POP Account" or try again.+
+The server error encountered was: The connection to host mail.kahane.co.uk on port 110 failed.+
I haven't changed any settings in the preferances or done anything which may have caused this. Incase you need to know i am on a POP account.
I would much appreciate any help, thanks

Me too... it comes and goes. It all started when I got a wireless router.

Is it possible to configure an SNMP copmmunity string on an ATA 186 without accessing it via console?

I am trying to configure a particular SNMP community string on many ATAs for a Cisco 'Know the Network' project. On a Cisco ATA 186, you cannot telnet or SSH to it and the only way to remotely change the parameters are via the web GUI, which doesn't have the SNMP field available.
Is this possible without getting physical console access to the ATA?

No.
An ASA can, as you noted, restrict source and destination IP and port. To do what you are asking, one would need to prevent a string within the payload from being transmitted (or only accept certain strings).
You should just put the access-list on the destination device(s) restricting what host(s) are allowed snmp rw (as you alluded to). That's a very common implementation straight out of the textbook.

ATA 186 Reproducing DTMF tones from RFC2833 events

I am trying to get my ATA 186 (running version SCCP 3.x under CCM 5.04a) to reproduce received rtp-events. This is supporting a third-party IVR system that is connected via analog ports.
The IOS gateway that is sending the events is configured for dtmf-relay rtp-nte, and I can see the RTP events being received at the ATA. However, all I hear at the ATA is nothing or clicks.
I have the audiomode setting on the ATA set to 0x00150015 as is recommended in the ATA administrators guide.
Does anyone have DTMF working through the ATA?

Hi Kevin,
have you debugged the ATA with prserv.exe?
I had some issues in the past with a PESQ tester, and setting the audiomode to 0x00120012 helped for me.

ATA 186

hi, i have a problem with ATA 186
when I light on the ATA it work very well after a certain moment the calls doesn't pass anymore Im forced to reboot every time when this problem happend
thanks

IS this CCM? If so please report to IP telephony forum where there are many fellows that can help.
If it is CCME I would start looking at the status of the ephone, and try to ping the ATA when it freezes.

E61 SMTP Port problem

I have a E61 since a few days. Unfortunately I cannot configure the SMTP port. Here in the office the port is 2525, but obviously it is only possible to enter 3-digit-numbers in the profile.
Is there a workaround? The confuguration tool is of no use as well...

Hi,
the only way is to use change the smtp port to 3 digits.I don't know but it can be possible to add a second port number without to remove the port with 3 digits.
I hope it will be help.I have read in the discussion the same problem.Thats was the solution provided.

ATA 186 and Cisco CallManager

I am trying to setup a cisco ATA 186 for a fax line with Cisco Call Manager 6.1.xxxx) I have a telephone hooked up to the Cisco ATA 186 and I see it register with the CCM. I have a telphone connected to port one and I get a dial tone, I can call into the phone from an outside line but it seems I cant dial to an outside number all I get is silence.
Could someone point me into a direction on troubleshooting this issue?
Thanks!

Verify software versions first.
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr.html#wp50035
After that, you would really need to look at traces to find out why the audio isn't getting connected. Do phones on the same subnet have audio when you call in? Does this only happen on outside calls? If it only happens on outside calls, get a sniffer to see if you see the RTP traffic coming to and from the devices.

Cisco ATA 186 on Linksys SFE2000P-EU Single Collision Frames

Hi all,
Recently we've deployed a fresh installation. But from the start we had some issues with a fax connected via a Cisco ATA 186 to a Linksys SFE2000P-EU switch. Which then is connected to a Cisco 3560. All ports on the Cisco 3560 are looking fine, but if I look at the port to which the ATA is connected I see a lot of Single Collision Frames! Is this because the ATA is running on 10Mbps/Half Duplex? Because I don't get to see these errors when I connect the ATA directly to the Cisco 3560. And is it possible to solve this issue, because the customer is complaining about missing faxes.
Best regards,
Paul van den IJssel
Digacom

Paul,
Half duplex will certainly cause collisions (CSMA/CD). Force the device and the switch port it plugs into to 100 full duplex, or 10 full if neccessary. I had a similar issue with my old PCMCIA Xircom 10/100 card. When I force the settings, all is well.
Regards,
Christopher

Cisco ATA 186 and Vocaltec GateKeeper

I have problems registering Cisco ATA 186 at Vocaltec GK using h.323. Can anyone post some usefull suggestions?

Sorry, i don't fully understand your answer.
If it's possible explain please a bit more indepth what i should write in the following fields in ATA 186 config:
1) UID0
2) PWD0
3) UseLoginID
4) LoginID0
and maybe
5) AutMethod
any other fields values should be changed?
BTW, right now i'm getting following output with prserv:
