How do I enable Exchange 2010 MWI with Call Manager 7.x?

  • Artikel

With Exchange Server 2010’s new messaging waiting indicator feature, my customer, from a school district in Colorado, was trying to get this to work.

Here is a reference I found created by David Howe:

To enable MWI

1) Open Cisco Unified CM Administration

2) Click System >  Security Profile > SIP Trunk Security Profile

3) At the Find and List SIP Trunk Security Profiles screen, click the FIND button

4) You’ll likely then see at least two SIP Trunk Security profiles (i.e. Non Secure, Secure).  Select the profile used by your SIP trunk with Ex2010UM.

5) From the SIP Trunk Security Profile Configuration menu, verify that Accept Unsolicited Notification is enabled.

                Note:  If your SIP trunk to UM is configured to use Digest Authentication, also be sure to select the option Enable Application Level Authorization.

6) Commit changes by clicking Save (this will restart all trunks associated with the security profile)

    CR, Are you running 2010 or 2007? Native MWI only works with Exchange 2010 UM. If you have 2010, take a look at the cisco config notes: http://www.microsoft.com/downloads/details.aspx?familyid=68b43d3c-7c84-4c2f-bfd7-98754970d70e&displaylang=en Also you need to allow for unsolicited NOTIFYs though in CUCM config for MWI to work.

    I have exactly the same configuration, and through the network monitor, note that the Exchange does not send notification to the UCM that have a voicemail, any ideas?
