Hi,

The ACK gets to our opensips because of the Route hdr (Route: <sip:10.61.20.146;lr=on>); opensips will further route the ACK based on RURI which is "sip:[email protected]"...is this domain resolvable by DNS and pointing to callee (10.61.20.200:5060) ? Callee has to place in 200 OK its contact address that can be used to route back to it...so if its contact "sip:[email protected]" does not point back to callee, it is a callee issue.

Regards,
Bogdan
