We have UCM 8.6 integrated with a Mitel MCD 5 system which terminates our PRIs.  When a UCM user calls out to the PTSN, the caller ID shows as the extension of the Cisco user.  I have External Masks set on all Cisco DNs.  I have also changed the Parameters in SIP trunk Outbound calls section to various things, yet it won't pass the external mask.  I have also set the Route Pattern to use "Calling Party's External Phone Number Mask". I am a bit stuck and would appreciate any and all help. ... View more

I have Unified Messaging setup between Unity Connection 8.6(2) and Exchange 2010 SP1.  When a voicemail is left in the subscribers UC box, it is delivered to exchange and the MWI light comes on as it should.  However, when the users views the email in Outlook, and it becomes read, the MWI light stays on.  It seems as if exchange is unable to communicate to UC that the message as been read or even deleted. I am not sure where to look next to see why exchange won't synchronize with UC. Any and all help would be greatly appreciated. Thank you, Jeffrey ... View more
