[asterisk-users] Weird SIP stuff

[Eric Wieling]

We are seeing something weird we haven't come across before. It seems they are sending us a different IP in the SIP from URI, than the IP they are actually sending us the traffic from.

Basically, the traffic is coming from 65.211.180.237 but the header is:

f: <sip:+1347545xxx at 199.173.94.80:5060;user=phone>;tag=4-45026-159e4a6-995949f-159e4a6


Does anyone know if this is normal and how I might make it work with Asterisk.   Incoming calls are not matching the we auth on IP only
