I am trying to set up JUST Remote Call Control (RCC) between Cisco CME and Lync 2010.
I have been able to get Enterprise Voice to work (making calls to extensions from the PC) but the company wants Lync to connect the call with the actual Desk Phone, not the computer speakers/headset.

I have defined a static route using this command:

PS C:\> $TCPRoute=New-CsStaticRoute -TCPRoute -Destination "X.X.X.X" -Port 5060
 -MatchUri ""

PS C:\> Set-CsStaticRoutingConfiguration -route @{Add=$TCPRoute}
PS C:\> Enable-CsTopology

(X.X.X.X being the IP of our CME server)

All of it worked as expected (at least it did not complain).
I then went into topology builder and added a Trusted Application Pool, and Published the topology.

I then enabled a user for RCC Only in the Lync Control Panel on the Front End server and used the following values for the Line URI and Line Server URI (YYYY being the extension and X.X.X.X being the IP of our CME):

Line URI:  tel:YYYY
Line Server URI: sip: YYYY@X.X.X.X

When I attempt to make a call to an extension in Lync, it appears that calling is completely disabled. All the call icons are greyed out.

Can anyone please point me in the right direction?
