Hi All,

I am facing an issue related to G723 codec. The scenario as follows

Call between sip-communicator and Grandstream hard phone with supported
codec as G723 codec. sip-communicator is a caller. The mapped codec sent in
200 ok for invite is G723 from Grandstream.

Granstream is sending g723 packets with bit rates set to 5.3 Kb/s but
sip-communicator is sending g723 packets with bitrates set to 6.3Kb/s. Due
to this

I can hear the voice from hardphone but not from sip-communicator.
sip-communicator is not dynamically adjust its bit rate to 5.3 may be it
expects 6.3 always.

Is this problem fixed already? Is there a patch for this?

I would be very thank full for the valuable response.

Thanks,
Ram

Hi,

this codec is handled by JMF. I don't know does it support this or just a bug and cannot switching to it.
Will have to investigate this.
I'm creating an issue on this and will report as soon as there is any result
Thanks for reporting this. And you are welcome for any patches :slight_smile:
