BZZZ WRONG.

The SDP is 100% valid.  The SDP is saying ULAW payload 0 and Speex on payload 98.  0 without an rtpmap means ulaw.

Hi,

i am not sure but i think your sip client is sending invalid SDP. it should look like this instead.

m=audio 1935 RTP/AVP 0
a=rtpmap:0 SPEEX/8000


m=audio 1935 RTP/AVP 0
a=rtpmap:98 SPEEX/8000
