CallManager 7.0 Microsoft Lync 2010 Integration

[dtom]

We are currently running CUCM 7.0.2 and Microsoft Lync 2010 and want to be able to have Lync clients make calls from Lync.  There are lots of documents that talk about the integration and this makes things very confusing (as to what to do).  What are our options here?  Which option is the best?  Which options is the easiest?

Hi, 

First of all you'll need to upgrade CUCM to 7.1.5 or later according to:

CUCM 7.0 might work, but it was not tested. The integration needs to be done using a SIP trunk between the servers. You can refer to the guide below:

I also found this guide on the MS site:

Hope this helps!
