Can dial from but not dial to extension

Arch = x86_64
OS = CentOS-6.4 (freepbx)
Asterisk = 11.0.3
FreePBX = 2.11.0.1

I am trying to configure a Snom870 as extension 41715. I can call out to other extensions from that device but when I attempt to place an internal call to it I get the AVR ‘The person at extension 41715 is not available, blah-blah’. This is what I see in Asterisk.

I have attempted a line by line comparison of the phone configurations and cannot identify any differences saving only that the identities are naturally different.

What am I missing?

Problem was caused by the “server type support” setting on the user identity SIP tab being set to DEFAULT instead of ASTERISK.
