I'm having some problems with incoming calls on 3CX. I have an N95 logged in on 100, and X-Lite on 101. If I set the sipgate line to go to X-Lite, the phone rings as it should, but if I set it to the N95, I get some weird messages in the logging, and the phone doesn't ring. Code: 00:56:11.339 [CM503008]: Call(16): Call is terminated 00:56:11.336 [CM503015]: Call(16): Attempt to reach <sip:firstname.lastname@example.org:5060> failed.

The N95 is registered and can make and receive calls from/to X-Lite. Anyone have any ideas? Thanks.
