In looking at the trace, the ACK is going back to the original call destination (205, at IP 10.7.6.214). Does this happen only when the call is forwarded?
I'm confused by this (message 6 in sub2.xml): SIP/2.0 100 Trying From: <sip:[email protected] <sip%[email protected]>>;tag=b6231ca6 To: <sip:[email protected] <sip%[email protected]>> Call-Id: MDI4MTQ0MTE1MzJkNjE0Zjk1ZjlkY2Q4NWJkZjkzMGI.
