Good Day:
I'm in the process of upgrading our Exchange environment to the 2013 version and have encountered problems getting Unified Messaging to work fully. I believe the problem lies in the SIP configuration on the vMCD (v 7.1PR1) and or the MBG (MiCollab 6.0SP2 in Server Only configuration). I believe the problem lies in the SIP configuration because Exchange UM (voicemail) functions properly when calls originate from within our environment. When attempting to call the auto-attendant or allowing a call originating from outside to ring unanswered, however, I hear only silence.
We are using a SIP provider for our external telephone service and utilize the MBG as an external proxy for the vMCD. Our Exchange 2007 environment is still running in co-existence with the new Exchange 2013 environment. There are no issues with voicemail from external sources to exchange mailboxes still hosted on the Exchange 2007 servers. The SIP Peer Profile for the Exchange 2013 server is configured per the recommendations in the "Configure the MCD 6.0 for use with Microsoft Exchange 2013 UM (SIP CoE 13-4940-00274)" Technote. The SIP Peer Profile and the COS definition for the Exchange 2007 and 2013 servers are similar, though slightly different due to adherence to the technote. Turning up the verbosity on the Exchange UM logs appears to indicate the call is being received and answered by Exchange.
Any help that can be provided would be greatly appreciated - It's been about 2 weeks of head scratching to this point. I can gather packet traces if that will be helpful, but first wanted to get this conversation started.
Thank you,
Stan
