Re: [TIProtocol-askcisco] TIP on TP Server Info Inquiry

David,

Thanks for your reply.
Our goal is to be TIP compatible with cisco devices. 
Firstly we want to achieve successful TIP communication between our
tool(endpoint) and TANDBERG Telepresence Server 8710 which as I found
that is compatible with TIP.
What we did are follows:
Make sip call with these settings:
m=audio ${A_PORT} RTP/AVP 96 9 0 101
b=TIAS:128000
a=rtpmap:96 mpeg4-generic/48000
a=fmtp:96
profile-level-id=16;streamtype=5;mode=AAChbr;config=B98C00;sizeLength=13;indexLength=3;indexDeltaLength=3;constantDuration=480
a=rtpmap:9 G722/8000
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
m=video ${V_PORT} RTP/AVP 112
b=AS:4096
b=TIAS:4096000
a=sendrecv
a=rtpmap:112 H264/90000
a=fmtp:112 profile-level-id=4d0028;packetization-mode=1

Than did TIP negotiation on video port+1(64181 in this case) using
libTIP.
Here is what we get from TANDBERG Telepresence Server 8710:
v=0
o=CODIAN 1328705765 1328705765 IN IP4 150.199.99.228
s=-
i=TANDBERG Telepresence Server 8710 v2.1(1.37)
c=IN IP4 150.199.99.228
b=AS:1920
t=0 0
m=audio 51732 RTP/AVP 96 9 0 101
a=rtpmap:96 MP4A-LATM/90000
a=fmtp:96 profile-level-id=24;object=23;bitrate=64000
a=rtpmap:9 G722/8000
a=rtpmap:0 PCMU/8000/1
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15
a=sendrecv
m=video 64180 RTP/AVP 112
b=AS:1920
a=rtpmap:112 H264/90000
a=fmtp:112 profile-level-id=42e016;max-mbps=108000;max-fs=3600
a=sendrecv
  
but we never received any TIP packets from TANDBERG Telepresence Server
8710 and immediately after SIP call we get h264 hd720 black video with
30fps.

Maybe I miss something and did it wrong way.
In attachment is pcap file with communication between our endpoint and
Tandberg which should be helpful.
IP adress of our endpoint: 158.197.28.58
IP adress of tandberg: 150.199.99.228
 
Hope it will be helpful to identify what is wrong in our setup.
Regards
Martin.
