Im attempting to find a way to determine an upstream devices signaling
IP from sip messaging.  Let me describe the flow

customer -> switch -> routing server

(all terms used below are in the context of the call flow above)

I want to find the signaling IP of the customer.  I have found that if
the switch sends SDP with the INVITE, and the switch is not set to route
media, I can get the customer signaling out of the SDP connection
information.  This however is not a viable solution because it is likely
some customer will be sending media through the switch.

Does any one know of a way to possibly determine the upstream customer
signaling ip from the routing server?
