Step 4. Assign Location Profile to Pool
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
A Communications Server pool hosting Enterprise Voice users requires a default location profile in order to route outbound calls. Different pools at various locations will require different location profiles
To assign a location profile to a Communications Server pool
Click Start, point to Programs, point to Administrative Tools, and click Office Communications Server 2007. The Office Communications Server 2007 administrative snap-in shows your Communications Server 2007 topology.
Expand the Forest node.
If you are configuring a Standard Edition Server, expand Standard Edition Servers, right-click the Standard Edition pool that you want to configure (not the server itself but the pool-level node for that server), point to Properties, and then click Front End Properties.
If you are configuring an Enterprise Edition Pool, expand Enterprise Pools, expand the pool that you want to configure, right-click Front Ends, and then click Properties.
On the Voice tab, select the default location profile for the pool. (To view the location profile, click View.)
