UM Exchange integration problem
« on: April 29, 2011, 05:10:37 PM »
Hello,

I have Exchange 2010 configured as voicemail but am having a problem.

Currently running:
Release 4.0 SP2
Active load 10.0.2.8

The problem occurs when someone sets there phone to DND, or forwards it to voicemail, or to an external phone number.
When they do that and an outside caller calls the exchange autoattendant and dials thier extension the call is immediatly disconnected.

I have tried using the SIP Peer Profile in Mitel TechGuide "Configure MCD 4.0 UR3 for use with Microsoft Exchange 2010" (SIP CoE 10-4940-00117).
See Attachment for that profile.

I have also tried to use SIP Profile from brantn's post in thread "UM Exchange integration question"

Here is my current Profile:

Not more SIP problems  ;D

I would...

1.) Start with a trace of the call probably monitor the port of the exchange server and see what is happening.
2.) The DND issues that I have seen and is very similar to your issue can be resolved by a couple means...
     A.) Make sure DPNSS/QSIG Diversion Enabled is no in system options.
     B.) Make sure public network to public network is enabled in the trunks COS.
     C.) Most important of all set Suppress Simulated CCM after ISDN progress to no in the trunks COS.

This should fix it if not remember SIP = Stiill In Progress.

I am experiencing the same issue where transfers to Exchange appear to be dropping the calls when DND is on (We've discovered that it's actually one way audio and not a dropped call though).   When we perform a Wireshark on one call with DND on and one with DND off the calls look quite different:

Without DND:

|Time     | 10.1.1.31                             | 10.1.1.33                             |

We believe that this also happens in a busy condition on the users' extension.  Any ideas or pointers are appreciated!

That is correct it is an issue with signalling check step 2 in my post it resolves the issue.
