[Asterisk-Users] Detect alternate line in Broadvoice inbound context

[Mark Hulber]

I have a single Broadvoice account with more than one number.  I am 
trying to distinguish between the numbers on an inbound call.  I have 
already tried using different incoming extensions that match each number 
but it always defaults to the primary.  Someone earlier mentioned 
SIPGetHeader as a possible solution but I'm not sure how that would 
work.  The only field that might possibly contain the distinctive number 
that I can tell is "list_route" but I have never used SIPGetHeader and 
don't know if it even makes sense in this case.

Does anyone have a solution for this?  I also tried DNID with no luck.
