Hi All,
I'm sure I've discussed this before, but I searched through my gmail
and google and couldn't find the answer.
Below is the SDP parameters from my sip provider. Is it mandatory to
always include the rtpmap details for PCMU/PCMA codes? For example
something like 'a=rtpmap:8 PCMA/8000' and 'a=rtpmap:0 PCMU/8000'?
I'm using sipdroid on android and it rejects this with 'codec not supported'
Thanks
