    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:

    Code:

    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,

    then you need to configure your device which answers Not acceptable here (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
