I am trying to configure an IP Communicator ext. for the first time. Communicator appears to register but no extention is assigned even though one is has been assigned in CallManager. It appears to be registerd but when I look at the device configuration page CallManager 1 and 2 are not active but the 3rd CallManager which is the router for srst it is active. I am trying this across a vpn and I setup the IP Communicator across the VPN so I don't think anything is blocking it.
I'm sure it something simple, it just escapes me.
