[asterisk-users] Internal CallerID problem

[Mark Bell]

Hey Guys,

I have something that just started happening. When my users call each
other on their 5 digit extensions their CallerID is showing as
XXXXX at 10.25.2.50  (XXXXX would be their Ext. and 10.25.2.50 is my
server) Calls in an out to the outside world are fine. 


I have scoured my configuration and can't find what would be causing it.
I have checked the sip.cfg in the polycom's and URI dialing is disabled.
What am I missing?

Trixbox 2.2.3 
Asterisk 1.2.18
Polycom IP550's with 2.2 software


Regards
Mark
