Communicator Drops Call When Put On Hold

Question
-
Hey,
This questions relates to OCS 2007 R2.
We have been using a Dialogic Media Gateway to route PSTN calls to our legacy PBX. This has been working perfectly for over a year now without any problems.
We have just installed a Cisco 2800 (Cisco Unified Border Element) to connect us directly to SIP trunks from our Telephone provider. I have migrated a number of test users to the new Gateway. Everything seems to work correctly but one thing. When I put a call on hold I get the following message -
"Call cannot be placed on hold. Your speaker and microphone have been muted."
While the call still appears active when I un-mute the call the line is dead - I cannot here the caller and they cannot hear me. The call does not disconnect until the caller hangs up the phone.
My first thought is that is must be the Cisco Gateway causing the issue as there was no problem using the Dialogic Gateway. My telephone provider thinks that the issue is with mediation server.
Have you got any fixes or ideas on how I can troubleshoot this?
Thanks,
Andrew

This is not an uncommon situation when the service provider has not gone to the trouble to certify in the OIP program. I would be surprised if you said they had and were stilling having this issue.

In saying that this document may help with the configuraiton with the CUBE. Although this is for CUCM it may be a good guide to helping you with your setup. Also take note of the IOS version in this docuement as you may be running into a bug on the CUBE.

Also you may want to run "debug ccsip message" on the CUBE to see what your SP sends back when you try to place the call on hold. Using the CUBE for interop to a SP is pretty common and a couple of SP's are using this configuration, so unless you have a buggy IOS or a misconfiguration on the CUBE it may be likely that if your SP hasnt qualified through the OIP that they are the issue. You also might want to ensure you have the latest updates on OCS if you decide to open a ticket with PS.
Cheers

Can I email someone log files from the Cisco CUBE and OCS for analysis?
Cisco CUBE has been setup accroding to the guidelines and is running the latest IOS.
Thanks,

Hi Andrew,
Did you find the solution?

I'd say CUBE is acting not as quite expected, because the invite from mediation server has a SDP with a=inactive, yet the invite sent by cube has a=sendreceive.Friday, February 10, 2012 2:10 AM
