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

Martin,
It is not obvious to me from the capture as to why no video is being transmitted. I suspect that the Telepresence Server does not think that TIP negotiation has completed on the video channel, as this would trigger a SIP re-INVITE and there is no such re-INVITE in the capture. I need to see the Telepresence Server event log to see if any problems are reported there.
Unfortunately you are using Telepresence Server v2.1 which is a little old now and probably is less resilient to problems in the TIP messaging. You might have more success with version 2.2 (which has been released for some time and can be downloaded for free).
Regards,
Thomas

David & Thomas.
Sorry to bother you again.
We correctly set up our endpoint with Telepresence Server but after successful TIP negotiation are able to received from Telepresence Server just audio and no video.
I have no idea what could be wrong.
I check also bandwidth setting in telepresence server and there is set maximum 6Mbps.(both to and from endpoint) In attachment is .pcap file with communication between our endpoint and telepresence server. Hope it will be helpful to find the reason that we are able to receive just audio.
Thanks in advance for any hints.
MaRTiN.

Although this document is for TelePresence Server 2.2 (the version being usied 2.1), the wording is only slightly different but is essentially the same instruction/configuration.

However, you are dialling into the TelePresence Server so you also need to configure one or more of the “Call-in match parameters” under “Configuration” for this endpoint. We recommend configuring the “E.164” parameter: this should be the SIP username of the endpoint (i.e. the section of the URI before the @ sign); in your pcap file your endpoint is seevogh@158.197.28.58:5060 so the E.164 should be set to “seevogh” (without the quotes).
