| Yeah, the problem is on the Mitel, I'm sure. What is happening is that the Mitel is getting the SIP request but doesn't know what to do with it. If I was using SIP trunking with my ISP or phone company, I'm sure that I could figure out how to just forward the request, but since I want the Mitel to do the conversion from SIP to PSTN, I'm at a loss.
We did have the Exchange UM working with the play-on-phone but that's currently broken due to some other cert issues. It looks like Outlook can't talk to the UM server correctly because it is resolving the autodiscover service to an ip with a cert that doesn't match the names correctly.
We have Exchange UM up an working fine with the Mitel but I need to get the mediation server to be routing calls before I tie UM and OCS into UC (: |
