Harry, Yes, you are right. And the RFC says the same "... fields ... are mandatory in all SIP *requests*.". Nevertheless, the max_fwd header is not in the requests. I'm not feeling myself capable of continuing the investigation. Could you please try to reproduce the problem as described in my first email or in the asterisk issue tracker and confirm if you observe the described incorrect behavior (asterisk with pjsip not sending max_fwd header in INVITE, ACK, BYE, etc. messages)? I guess you don't even need softphones, nor special configurations, just check with pjsip logger or a packet sniffer what headers your current asterisk with pjsip is sending. If I'm right, this incorrect behavior is there from the beginning of asterisk/pjsip integration and should be observable in any version of asterisk with pjsip.

ACK and BYE both are requests, not response messages.
