[asterisk-users] Weird SIP stuff

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 but the header is:

f: <sip:+1347545xxx at;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
