[Asterisk-Users] SetCallerID based on extension

[Jodie Crouch]

I am going through previous posts, but I am not finding anything.  I
apologize if this has been covered already.

I want to be able to change the CallerID for outbound calls based on
the extension making the calls.  However, I don't really need this
level of granularity.  I have one asterisk box serving many markets. 
I want to set the CallerID to a local number in each market.  So, of
someone in Dallas, TX calls out it shows our Dallas number.  If
someone in Arizona calls out, I want it to show our Arizona number.  I
figured the best way to do this would be based on the extension, but
if someone else has a better idea, please let me know.

So, if we are going to set the caller id based on the extension, then
this is what I need to know how to do.

Right now, outbound is configured as below, in the extensions.conf file.

exten => _1NXXXXXXXXX,1,Dial(SIP/9725432876/${EXTEN})
exten => _1NXXXXXXXXX,2,Hangup


Please let me know how I can create this same process but change the
CallerID to 2134531762 instead of 9725432876 when someone calls from
extension 112 and to 9725432876 for extension 317.

Thanks!
