Problems to use GSM codec

[rfl2]

Hello,

I'm doing tests with 3CX and I'm having problems to implement the codec GSM. When I set my client to use this codec, I get this error in the client: Server Internal Error. I'm using x-lite as a phone client.

In the server, I get these messages:

10:08:45.718  Active calls counted toward license limit: []
10:08:42.703  [CM503020]: Normal call termination. Reason: Server Failure

Not implemented?? In the 3CX documentation, I read that was a standard codec.

How can I use GSM codec in 3CX?

Thanks,

Roger

Hi Roger,

Yes.. works fine just with ulaw and alaw.
...

then you need to configure your device which answers Not acceptable here (IP:10.10.42.109:5061)

10:08:42.687 [CM503003]: Call(12): Call to sip:[email protected] has failed; Cause: 488 Not Acceptable Here; warning: Media type not available; from IP:10.10.42.109:5061

to support GSM codec or configure your "GSM only" extension(102) as "PBX delivers audio=on"

This information is available in documentation, articles and training videos published on wiki.3cx.com.

If you need to play with specific details of SIP/RTP then you need to have advanced knowledge in this area.

Thanks
