I think the issue is that there is a proxy inserting an RR header with the 'lr' parameter in the middle of the flow. I'm sure if this were a straight UAC->UAS call, they'd interoperate fine. But the proxy is not forwarding this ACK to UAS B. -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/ _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
