asterisk users - Dec 2007 - Caller ID Issue

I have a strange issue with CLID that I would appreciate if someone
could point me in the right direction.  When a call comes in (either
from another SIP user on the same Asterisk box or from the ISDN PRI) the
Caller ID Name is displayed correctly, but the Caller ID Number seems to
be empty.  My Grandstream phone is setting the Caller ID number to the
registered account name while SJ Phone soft client shows the Caller ID
number as empty.
 
Any suggestions would be greatly appreciated.

Hi Sam,

some phones seem to hate phone numbers with strange characters in them;
those might be spaces, "+" signs, "-" dashes etc. and refuse
to display
anything at all. Perhaps the information is there, but it is in some way
or another taken as "invalid".

You could see what Asterisk "thinks" those variables are. A

NOOP(CALLER-ID-Info: ${CALLERID(num)} / ${CALLERID(name)})

in the dialplan, together with CLI and "set verbose 10" should show
you
lots of information.
