What format do your incoming caller IDs come in?   (use a NoOp() or Verbose() 
statement to write to the log.)  One would expect outgoing caller IDs to be 
set in the same format  (but speak to someone at the telco for confirmation of 
this).  Our provider  (in the UK)  expects our outgoing caller IDs to include 
the STD code, but without the initial 0.  So 065631040 would be sent as 
65631040 .


Are you definitely allowed to set your own caller ID?  It may well be 
restricted to one of a range of "presentation numbers" assigned to you.


One other thing:  CALLERPRES() has been deprecated for awhile now, so in newer 
Asterisk versions you may need to write Set(CALLERID(pres)=allowed) instead of 
Set(CALLERPRES()=allowed .
