[SIPForum-discussion] SDP Message in SIP problem. Please Help.

[Kristine Regis]

Hi, I hope anyone could help me figure out what's the problem here.

I am currently developing a SIP Call. The flow of the call from INVITE 
to BYE is correct, as I assume since the server accepted it - the server 
is OpenSIPs. My SDP is as follows:

v=0
o=root 3457409648 3457409648 IN IP4 172.16.100.21
s=-
c=IN IP4 172.16.100.21
t=0 0
m=audio 5060 RTP/AVP 0 8 101
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000


I have this SDP and the voice streaming cannot be done. The caller and 
the call cannot here each other. I don't know what is the problem here 
or if the SDP above is wrong.

I hope you could help me solve this problem. Thank you.
