I'm trying to find a way to route inbound SIP calls, based on their source. For example:
SIPCarrier1 is coming from 22.214.171.124
SIPCarrier2 is coming from 126.96.36.199
If calls originate from SIPCarrier1, I want them to be passed to my UCM Cluster.
If call originate from SIPCarrier2, I want them to be passed to my Asterisk box.
I've played around with incoming called-number, trying to make it work with IP addresses, rather than phone numbers, but no luck.
Any ideas of where to start?
