G729 / PCMU - Callcentric

[mbeijen]

I have 3 DID's with CallCentric, the first line is a brand new line, the other 2 have been ported.

The first line works absolutly fine, the other two lines work fine as long as they go directly to an extention. When they go to an autoattendent, it's game over and the call gets dropped with the following message :

from 'bi-server:0/MediaServer':No RTP packets were received on 0000001C@:remoteAddr=204.11.xxx.xxx:54858,extAddr=76.212.xxx.xxx:9000,localAddr=0.0.0.0:9000

Callcentric did some research regarding this and told me the following:

On the first line the following codecs are used : G729,PCMU,PCMA
On the 2 ported lines it's just : G729 & PCMU

They were suggesting to disable some of the codecs in the 3CX system to see if that would help.

I looked around, and simply cant see a way to disable these at all. Is there a way? Does anybody have another solution or a suggestion?

Thanks a bunch!

Hi, Marco,

Both sets of codecs are good for PBX and for calls from/to this provider PCMU codec will be used independently of source or destination of call as well as independently of which line is used.

Definitely, it is not a codec issue.

This log entry just says that no RTP packets was received from remote party.
It is reported after call is dropped. PBX log contains other messages related to call. Please post it here to investigate source of problem.

Thanks,
Stepan

This is the piece from the 3CXPhoneSystem.trace.log , is this the one you were talking about?

We dont support G729. You must have your provider use G711 or GSM. If your provider does not support it you will have to use another provider.

 

[mbeijen]

I'm just starting with all this stuff, so please explain.

You're saying that you dont support G729, however when I route this call directly to an extention, it's working fine.

It's just when it's going to the attendend that the call gets dropped.

 

[Nick Galea]

Hi,

Probably your phone supports G729. So therefore it would seem that the VOIP provider and phone can talk to each other because they both support G729. However when it goes to our Auto attendant, it does not support G729 and can not communicate with the provider.

Just FYI, G729 is not supported for licensing reasons. Its licensing is prohibitive. GSM is more or less the same but is free. Use G711, or if you must use less bandwidth choose a provider that supports GSM.

 

[mbeijen]

This is what callcentric told me :

We placed test calls to all 3 of your numbers and the only difference we found is with the codec's that are being offered; and what your equipment responds with - although there is no actual "problem" in the signaling.

On the 2 ported numbers; for example 18324822559 we offer:
G729 & PCMU

Your equipment answers these calls with only PCMU offered; and then it (your equipment) drops the call.

On the original number we assigned to you we offer:
G729 , PCMU & PCMA

and your equipment answers these calls with: PCMU and PCMA.


So the call gets dropped with PCMU (which is 711 right?)[/i]

 

[Nick Galea]

At present Call centric is not a supported provider, i recommend you use a supported provider instead.
