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.

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!

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.

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.

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:

Issue on Cisco ATA 186 used for Fax

Hello everyone;
I have a cisco ATA 186 connected to an analog Fax on one side, and the other side is connected to the network containing a CUCM 8.6.
The problem is that when i try to send a fax throught it , half of the paper is transmitted or an usual occupation tone comes; while vocal communications are performed normaly.
Any idea of what could be the problem.
NB: the fax emission is between two distant sites relied by optical fiber.
Regards.

Hello Frank;
Thank for the reply.
Here below more informations about the issue:
- It does work sometimes, but it did never worked properly.
- the problem is there for both sending and receiving.
- for the PSTN transport, i have no idea.
- I tried to change the ATA by another, still the same problem.
- ATAs work properly for voice communication.
- when i call this fax number internally the signal comes along.
- the problem is when faxing internally, it isn't used for external faxing.
- the call flow for internal faxing is like this:
Analog fax (in site A) > ATA (in site A) > access switch (in site A) > core switch (in site A) > cucm (in site A) > Core switch (in site A) > router (in site A) > optical fiber > router (in site B) > core switch (in site B) > cucm (in site B) > core switch (in site B) > voice gateway 248 (in site B) > Analog fax (in site B).
the problem occures when sending internal fax between these two sites A and B, when calling site B from site A, the ringing tone comes aloso the fax signal, but when i try the send the paper the stange tone come along and only half of it pass and it get to the site B as a blank paper or a half blank paper.
for any more explanation, don't hesitate to ask me.
thanks again for your time.
Regards.

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.

!!cisco ATA 186, back to back.SOS

hi there, just enlighten me on cisco ATA 186 back to back config, my network is like:
phone---ATA----Switch---ATA---Phone,wnat to know the sample config, if this not possible, fine ,then let me know what shud i configure to get a dial tone,as im getting a busy tone than a dial tone, or lastly what shud i do to reset the ATAs to factory default settings,
cheers
shukky

If your ATA is running skinny right now then I think it is not possible (because no callmanager in the picture).
But if you load your ATA with a SIP image then in the SIP proxy filed, you can specify the IP address of the other SIP ATA and then you should be able to call from one ATA to another.
I haven't tried that with the ATA, but done with the 7940 phones and it worked.
To get the dial-tone, you must configure a number for the ATA first. (UID)

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 Issue to send faxes

Hi,
I have an issue with ATA 186 to send faxes. I have tried many things, but the fax sending is unsuccessful. I am not a VoIP expert, so it is pretty hard to me to identify the difference between some commands. This is the topology of the network:
Fax Machine --- ATA ---- CCM ---- VoIPGW --- E1(PSTN)
I have the following values in ATA:
AudioMode: 0x00120012
ConnectMode: 0x00008400
This is the dial-peer configured to that Fax:
dial-peer voice 1010 voip
call-block translation-profile incoming 110
call-block disconnect-cause incoming call-reject
preference 1
destination-pattern 1044
voice-class h323 1
session target ipv4:10.15.190.4
dtmf-relay cisco-rtp h245-signal h245-alphanumeric
codec g711ulaw
fax rate disable
fax protocol pass-through g711ulaw
no vad
Aditionaly I had the following lines in VoIPGW:
ccm-manager fax protocol cisco
mgcp
mgcp fax t38 ecm
Recently I changed to:
no ccm-manager fax protocol cisco
mgcp
mgcp fax t38 inhibit
Not sure if I missing something, in the other hand I would like to know which is the different between fax protocol pass-through g711ulaw and modem passthrough nse codec g711ulaw
Thanks for your comments....

Hello,
There is one relly important detail on this matter, is the fax machine a super G3 fax machine? this is because as you mention there are some limitation for the ATAs to work with fax machines and modems, this is because the device was not designed for this purpose.}
In the follow link you could find some information about the ATA configuration for faxing:
http://www.cisco.com/en/US/partner/products/hw/gatecont/ps514/products_qanda_item09186a00800946e1.shtml
Another important detail is check if your gateway supports the type of faxing that you are trying to do
http://www.cisco.com/en/US/partner/tech/tk652/tk777/technologies_tech_note09186a0080159cf3.shtml
Finally this are the configuration steps for you voice gaway:

Hello, already replied in another thread, please do not open duplicates.

ATA-186 can be registered with CUCM v10.5

Hello guys ;
Please confirm me that ATA-186 can work with CUCM v10.5 ? .

I followed this link from another post regarding ASA not registering for an older issue.
http://www.cisco.com/en/US/docs/voice_ip_comm/cata/186_188/3_0/english/administration/guide/sccp/sccpaape.html#wpxref59054
Follow the part that mentions setting the SID0 & SID1 to "." no quotes. I did this and my ATA registered to CM. Screen caps attached.
I have a Cisco ATA 186 running on 10.5.1 and it shows to be registered. I can make calls on it. Not sure how it will do for faxes. HTH Please rate.

ATA 186 for FAX With CME

Hi,
I have ATA 186 connected to my network when i connect a phone it works but when I connected fax machine i cannot recieve or send faxes...do I need to do any configurations in ATA...please check the attachment..

you'll need dial peer(s), on your CME router, that enable FAX passthrough as well as a few other pieces.
please see the following link for Config/Troubleshooting ATA-186 with FAX:
