Let me clarify.  

Diversion: "7024101040"<sip:7024101040 at 192.168.1.254>;privacy=off;reason=unconditional;screen=yes

7024101040 instead of 1040 in the description and user portion of the URI.

Is there a way to force UCM to send the 10 digit number (external mask) in SIP Diversion instead of the 4 digit extension?
