[Asterisk-Users] Changing caller id on transfer

[Mojo with Horan & Company, LLC]

We just had to bite the bullet and recognize the number following the 
prepended string as being internal or external.  We prepend the string 
"INT:" so if I call my coworker, he sees "INT:Mojo" as the caller id, or 
"INT:112" if I have it set to do extensions instead of names.  if an 
example incoming call came to me and I transferred it to my coworker, he 
might see "INT:DIR ASST" or "INT:18005551212", respectively as 
configured.  pretty much, if the callerid number is just three digits 
long, we know it's an internal extension calling us directly and not 
transferring somebody to us.  If there's no INT: prepended, we're seeing 
the first incarnation of the call.  The only problem I've had is when it 
gets transferred again, another INT gets on there: "INT:INT:Mojo".

You probably have separate contexts for when you dial another internal 
extension and when an incoming line comes in. To try this you would add 
the prepended strong to the internal context.
