First thing to check:  Are you sure that your mobile telco actually let you 
set your own ident on outgoing calls?


Just because Asterisk requests a particular caller ID, does not mean that the 
equipment downstream is necessarily going to honour that request  (or even 
have any way to do so; Asterisk won't protest if you Set(CALLERID(num)=...) 
and then Dial() out through an analogue line).  With many telcos, you can only 
ident as a number you are entitled to use.  If you request a number that isn't 
yours, the call will be made anonymously, in accordance with  (someone's idea 
of)  the Principle of Least Surprise.

And with a very few legitimate exceptions, this is entirely Right and Proper.  
Subscribers have a reasonable expectation for the number shown on the phone to 
be the actual number from which they are being called.  If it was any 
different, we would have unwanted callers spoofing caller ID right, left and 
centre.
