I've just added Conductor and virtual TP Server to my CUCM 8.6.2 in order to provide videoconferencing capabilities for all my endpoints (standard IP Phone 8945 / 9951, MX200, CTS , TX9000) using Ad Hoc.
RendezVous is not configured yet.
Here are my versions : Conductor XC2.2.1 , TP Server (virtual) 3.1(1.96) , CUCM 126.96.36.19900, phones with up to date fw.
Conductor is added as a conference bridge on CUCM and is registered. TP Server is active as a conference bridge from Conductor point of view.
When doing an Ad Hoc conference from 3 * ip Phone 8945, I've around 30 seconds video (and only 1 pip at the bottom of ip phones screen) then it hangs. Around 30 seconds later session is automatically disconnected on one of the phone and other phones revert back to a p2p call.
Conductor : B2BUA disconnected call on the Ingress saying "Failed to send out mid-dialog request due to a transaction timeout"

I've set traces to Detailed and I can see the first INVITE-> TRYING -> RINGING -> 200 OK w/SDP exchanges between CUCM and Conductor
Then 3 seconds later there is a Re-INVITE w/SDP from Conductor (for what reason I don't know), and the CUCM says TRYING but no more than this.
Maybe my timeout from Conductor pov and the no answer to the Re-INVITE are the same...
I've seen some bug related to Re-INVITE CSCuh79981, maybe I'm facing this issue.
Any other idea ?
Just found this CSCuj85594
Calls from CUCM would route through Conductor to TPS and connect. After 30sec, TPS would send a re-invite back to CUCM. The SIP re-invite was dropped at CUCM as the message size was to large causing the call to drop.
Increase SIP message size on CUCM
Trying and let you know...
Unfortunately SIP Max Incoming Message Size is already set to 1100 so I'm not matching CSCuj85594
I hope 1100 is a typo - should be 11000 or bigger... (default is 5000)
In the CiscoLive 2013 slidedeck BRKEVT-2811 they mention even 12000...
Was this specific to 8.6.2 version, I have a cluster that is having a very similar problem and the max sip incoming message size is already set to 11000. The calls from this cluster to the conductor/TP are coming through a Intercluster Trunk. The cluster that is "attached" via the SIP trunk to the Conductor is running 9.1.2 and it works fine.
I am trying to determine if the problem is due to the ICT is the issue or the version of the CUCM.
The error in the TP is Error ending call due to network error during ACK transaction.
Thanks for any help.
I have encountered similar problem on my customer's site.
The symptom was almost same as this. Exactly same entry of TS event log ("Ending call due to INVITE transaction timeout") has been appeared.
However, the environment was,
CUCM : 10.5
Conductor : 2.4.1
TS : virtual TS 4.0
Jabber for Windows (video client) : 10.5
Is this problem still exist and have never fixed yet?
To the older postings, especially regards TelePresence / video I strongly recommend to use later or better said the up to date version of CUCM.
Besides that, often when calls fail there is something wrong in the network, like firewalls/algs/nat
where it should not be, configurations or DNS records are not ok and so on.
Sip is a protocol which sends out a message and in many cases expects a message back.
If for what ever reason that message does not arrive or is changed it will most likely fail.
Please remember to rate helpful responses and identify
I'm sorry to late reply.
I have never found any solution about this. However, it's in the customer's network and there may be some router/firewall between CUCM and TS, I heard.
Now we're asking to test that putting TS onto the same network with CUCM and how it will work.
My problem was related to the "SIP Max Incoming Message Size".
Even though I was running 10.51. My CUCM had been upgraded many times and the setting was set at 5000 which I guess came from earlier versions. As soon as I changed this setting it all sprang into life.
Hope this helps someone.
