[Serusers] ACK

[Klaus Darilion]

Waht is "my-IP"? IP of caller or callee or SIP proxy?

The URI in the ACK is typically the URI in the Contact header of the 200 
Ok message. Thus, the URI in ACK depends on call direction, and wheter 
the caller is a strict router (old SIP RFC) or loose router (RFC3261).
