Where is the latest PBX compatibility list for Exchange 2010 Unified Messaging?

  • Artikel

I had a couple of Exchange 2010 voicemail questions from a school district from northern California replacing Cisco Unity voicemail with Exchange 2010 UM.

 

Where can I check if my PBX has been tested with Exchange 2010 UM?

We have an updated Telephony Advisor list for Exchange 2010.  You can check SIP gateways, TDM PBXes that have been tested as well as SIP PBXes that have been tested with Exchange 2010 Unified Messaging.

I have heard Exchange 2010 UM does not work with Cisco Call Manager 5 or higher, true?

No, we have tested Exchange 2010 UM using direct SIP to CCM 5,6, and 7.

How do I upgrade to Exchange 2010 UM from Exchange 2007 UM?

It is a fairly basic process, you install Exchange 2010 UM server into the same dial plan as Exchange 2007 UM, point the SIP gateways or direct SIP PBXes to the new 2010 UM server, migrate mailboxes to 2010, migrate any custom prompt autoattendants, decommission Exchange 2007 UM server.

Exchange 2010 UM supports coexistence as well and will route any Exchange 2007 voicemails to Exchange 2007 UM servers.

 

More on the UM upgrade process here.

 

Can I connect multiple PBXes to Exchange 2010 UM and leverage the same dialplan and subscriber access (pilot) number?

Yes, this works and is supported. Here is a list of supported scenarios:

 

A single dial plan that represents a subset of extensions or all extensions for an organization with one PBX or IP PBX.

A single dial plan that represents a subset of extensions or all extensions for an organization with multiple networked PBXs or IP PBXs.

Multiple dial plans that represent a subset of extensions or all extensions for an organization with one PBX or IP PBX.

Multiple dial plans that represent a subset of extensions or all extensions for an organization with multiple PBXs or IP PBXs.

    I think you should also put here some OCS-integration-related things, namely: Office Communications Server   Communications Server 2007 can't determine the version of the mailbox for a UM-enabled user. So when a call is received by Communications Server 2007, and it redirects the call to another UM server in the same dial plan, either an Exchange 2007 UM server or an Exchange 2010 UM server might take the call. This causes a problem when you perform a partial upgrade, because the incoming call will fail if it's received by an Exchange 2007 UM server and the UM-enabled user's mailbox is on an Exchange 2010 Mailbox server. The call will fail because Exchange 2007 UM servers can't process calls for UM-enabled users who have Exchange 2010 mailboxes. The reason the incoming call will fail is that Communications Server 2007 can't tell whether the UM server that it redirected the call to is an Exchange 2007 UM server or an Exchange 2010 UM server. If Communications Server 2007 is used as an IP gateway, and there are Exchange 2007 mailboxes that are enabled for UM, a new SIP URI dial plan will be required. The new SIP URI dial plan must contain only Exchange 2010 UM servers. The new dial plan is required to ensure that incoming calls are redirected only to Exchange 2010 UM servers. source: http://technet.microsoft.com/en-us/library/dd335126.aspx

    Ricsip, Is this true if you route all incoming OCS calls to Exchange 2010 UM only? My understanding is the 2010 UM server can hand off the call to the 2007 UM server which replaces the need for OCS to be able to route to the correct voicemail account.
