RFC 3261 gives (by way of example) an ACK that is sent directly to a remote phone via its Contact: header address. Is this the _only_ way of doing this, or may ACK also be passed through a SIP proxy?
If your Kamailio adds Route header to INVITE, ACK will be routed based on that instead of Contact URI.
