Great examples Matthew, really appreciate it. This is exactly what I've been
searching for!

Mike,
I have a similar setup (I even use Vitel) and the easiest and
cleanest method that I have found to accomplish this is with the
AstDB. You can simply create a cross-reference of DIDs and Internal
extensions similar to extdid/200 => 5551112222 ... extdid/250 =>
5551112272 in the AstDB. Then you can change your outgoing dialplan
to change the caller id based upon this cross reference. Example:
exten => NXXNXXXXXX,n,Set(outgoingCID=<MAINNUMBER>)
exten => NXXNXXXXXX,n,
GotoIf($[ ${DB_EXISTS(extdid/${CALLERID(num)})} = 0 ]?makecall)
exten => NXXNXXXXXX,n,
Set(outgoingCID=${DB(extdid/${CALLERID(num)})})
exten => NXXNXXXXXX,n(makecall),Set(CALLERID(num)=${outgoingCID})
...
You could even simplify your incoming context by cross-referencing
in the other direction. That is didext/5551112222 => 200 ...
didext/5551112272 => 250.
exten => NXXNXXXXXX,n,
Goto(internal-extensions,${DB(didext/${EXTEN})},1)
OR you could do something similar with LOCAL channels or with a Dial
command.
