3rd party TIP endpoint cannot join MSE 8710

Hello,

Our TIP endpoint (3rd party) is making a SIP/TIP call to MSE 8710. We offer H264 Main profile for video (as per TIP spec) and aac-ld for audio.

The initial SIP INVITE SDP offer is below:

v=0

o=root 2176 2176 IN IP4 74.122.25.116

s=Talk

c=IN IP4 74.122.25.116

b=AS:2304

t=0 0

m=audio 57080 RTP/AVP 111 110 96 0 8 101

b=TIAS:256000

a=rtpmap:111 speex/16000

a=fmtp:111 vbr=on

a=rtpmap:110 speex/8000

a=fmtp:110 vbr=on

a=rtpmap:96 mpeg4-generic/48000

a=fmtp:96 profile-level-id=16;streamtype=5;config=B98C00;mode=AAC-hbr;sizeLength=13;indexLength=3;indexDeltaLength=3;constantDuration=480

a=rtpmap:101 telephone-event/8000

a=fmtp:101 0-11

m=video 59080 RTP/AVP 112

b=TIAS:2048000

a=rtpmap:112 H264/90000

a=fmtp:112 profile-level-id=4D0028;packetization-mode=1

As you see we offer H.264 main profile.

Unfortunately MSE 8710 downgrades the call to audio only  - below is SDP from 200 Ok reply:

v=0

o=CODIAN 758959425 758959425 IN IP4 153.6.22.171

s=-

i=TANDBERG Telepresence Server 8710 v3.0(2.48)

c=IN IP4 153.6.22.171

b=TIAS:4256000

t=0 0

m=audio 58480 RTP/AVP 96 0 8 101

c=IN IP4 153.6.22.171

b=TIAS:256000

a=rtpmap:96 mpeg4-generic/48000

a=fmtp:96 profile-level-id=16;streamtype=5;config=B98C00;mode=AAC-hbr;sizeLength=13;indexLength=3;indexDeltaLength=3;constantDuration=480

a=rtpmap:0 PCMU/8000/1

a=rtpmap:8 PCMA/8000/1

a=rtpmap:101 telephone-event/8000

a=fmtp:101 0-15

a=sendrecv

m=video 0 RTP/AVP 112

Please not that when we make a direct TIP call to Cisco endpoint (CTS1000 or CTS3000) via CUCM and offer the same everything works fine.

What can be the reason for such behavior in the case of call to MSE 8710 ?

Thanks,

Sergey

Re: 3rd party TIP endpoint cannot join MSE 8710

I would get a packet capture and see if TIP (RTCP) negotiation is correct for Video channel.

Normally TPS logs provides very good information if negotiation is succesful or not. In the TelePresence Blog section you will find a TIP/MUX article that can be useful.

Re:3rd party TIP endpoint cannot join MSE 8710

Hi Sergey. Interesting issue. Not sure why its zeroing your port here. If you can provide the SIP log from TS and event log would be helpful. SW versions of devices would be great to know. Also, what is this 3rd party endpoint?

Re:3rd party TIP endpoint cannot join MSE 8710

Hi Patrick,

Thank you for your reply.

The 3rd party endpoint is our proprietary endpoint we are developing now. It supports TIP v7. 8710 is v3.

Please note there is VCS between our endpoint and 8710. Is this a legit scenario? Do we need to support CUCM trunking to VCS?

For now we do not have the log files.

Thanks,

Sergey

Re:3rd party TIP endpoint cannot join MSE 8710

What's the call path?  Is it Endpoint > CUCM > VCS > TP Server?

It's probably worth trying to mess with the call path - e.g. take CUCM out of the picture and/or take VCS out of the picture if possible to isolate the issue.

Also, have you tried manually adding the endpoint as a legacy TIP system to the TP Server?

Nick,

Thank you for the recommendation. We will conduct these tests and post the results here.

Nick,

We tried the direct call from our TIP Endpoint to Cisco Telepresence 7010 and got the same result - video is rejected by Cisco 7010 in 200 Ok SDP answer. The details are below:

1) Our SIP INVITE looks as follows:

The question is why does Cisco 7010 reject video (i.e. puts port 0 in SDP answer) ?

Thank you,

Re:3rd party TIP endpoint cannot join MSE 8710

Sergey,

Sorry I don't have the expertiese to troubleshoot all that output, but what do you mean "directed the call to the TP server 7010" ?

When connecting to the TP server via SIP (which is required for TIP to work) I was under the impression you needed some form of call control in the middle, e.g. VCS and/or CUCM.

Was the TP server using VCS as its SIP registrar, or did it have a SIP trunk to CUCM (or something else)?

To be clear, what I was suggesting was using VCS only, or CUCM only.  It's not clear what the call path was in this scenario, unless you were somehow dialling directly without call control in the middle?  If not, what was the call control?

Re:3rd party TIP endpoint cannot join MSE 8710

Nick,

Yes, we tried direct call from our Endpoint to TP server 7010. Both are SIP endpoints, both support TIP. Anything wrong with the direct call?

Earlier we tried via VCS, but the result was the same.

Re:3rd party TIP endpoint cannot join MSE 8710

Look at this

9333 2014/01/06 11:02:11.925 RTCP               Warning   Failed to send any TIP negotiation messages; negotiation failed

     9334 2014/01/06 11:02:11.925 TIP                Info      call N14: TIP/MUX negotation failed; TX: 3 audio, 0 video; RX: 3 audio, 0 video

You are using 3 screens in Contact header, is that true?

Please verify MUX/TIP is succesfully negotiated, please look at the TelePresence Blog MUX/TIP negotation for a sample, you may need a packet capture.

Are you doing secure call ?

In this scenario DTLS is negotiated first then TIP.

If DTLS fails, TIP is negotiated anyways, looks like TIP messages are not sent properly.

Re:3rd party TIP endpoint cannot join MSE 8710

Hi Gonzalo,

Thank you for your reply.

1) Yes, we are using 3 screens in the Contact header. That is correct.

2) In my understanding the call flow should be as follows:

     a) SIP/SDP offer/answer (i.e. INVITE, 200 Ok - both with SDP)

     b) As a result of step "a" both sides know media ports of each other (both for audio and video). So now they can start TIP negotiation by sending MUXCTRL message, etc.

     Definitely step "b" never happens because Cisco 7010 never provides video port to us in step "a", i.e. we cannot send MUXCTRL message to Cisco 7010.

Can you explain how TIP negotiation can happen if we do not know the video port?

3) The call is not secure, so no DTLS.

Thanks,

Sergey

3rd party TIP endpoint cannot join MSE 8710

You may need to start looking at a packet capture at this point.  You may want to also take a look at TIP V7 and V8 docs on the IMTC page to verify your implementation.

Re:3rd party TIP endpoint cannot join MSE 8710

Patrick,

Yes, we do have a packet capture. The SIP/SDP messages I showed earlier are copied from the Wireshark trace.

And we definitely looked at TIP specs. Our implementation expects the following call flow:

a) SIP/SDP offer/answer (i.e. INVITE, 200 Ok - both with SDP)

b) As a result of step "a" both sides know media ports of each other  (both for audio and video). So now they can start TIP negotiation by  sending MUXCTRL message, etc.

      Definitely step "b" never happens because Cisco 7010 never provides  video port to us in step "a", i.e. we cannot send MUXCTRL message to  Cisco 7010.

I would like to say that this call flow works fine with CUCM/CTS3000 and also with non Cisco MCU. The problem we have is only with Cisco 8710 and Cisco 7010.

Thanks,

Sergey
