Hello,
I'm currently working on a cisco devnet sandbox environment, which has a CUCM 9.1 and a Jabber guest server.
My goal is to connect a softphone i developped to this environment and receive video calls from jabber web pages.
The jabber page and the softphone are both running on my computer.
The SIP call flow is all done and works fine, but i get a void video port from the ACK request of the CUCM once the INVITE has been accepter.
This is the SDP packet which is in the OK response i send to CUCM after the INVITE from the jabber guest (replaced ips with {comments}) :
v=0
o=1120 181025627 181025627 IN IP4 {sofpthone computer ip}
s=operator1
p=1120
c=IN IP4 {sofpthone computer ip}
t=0 0
m=audio 35500 RTP/AVP 0
a=rtpmap:0 PCMU/8000
m=video 35505 RTP/AVP 96
a=rtpmap:96 H264/90000
And this is the SDP packet from the ACK request (replaced ips with {comments}):
v=0
o=CiscoSystemsCCM-SIP 85475 1 IN IP4 {CUCM ip}
s=SIP Call
c=IN IP4 {jabber guest ip}
b=TIAS:64000
b=AS:64
t=0 0
m=audio 17134 RTP/AVP 0
b=TIAS:64000
a=rtpmap:0 PCMU/8000
a=ptime:20
m=video 0 RTP/AVP 31 34 96 97
a=rtpmap:31 H261/90000
a=rtpmap:34 H263/90000
a=rtpmap:96 H263-1998/90000
a=rtpmap:97 H264/90000
a=content:main
a=inactive
As you can see, the video port has a value of zero, which obviously cannot be used to stream. What could be the cause of this ?
