That should work
Does this affect the call flow? I mean Ive read that responses to ACK requests are not that important.
per standard: there is NEVER a response to an ACK
Im a newbie in SER and sip so please bare with me. :-)
please always cc: to the list.

Sorry Klaus, I pressed reply instead of reply to all so the mailist was not CCed, :-)
I used the example configs v5 from Onsip.org and it didnt include an ACK handler. I added the extra code and no more warnings now.
Also another thing i had to do when i was setting up the example config file for NAT and Media proxy was to add a check for NATed caller before the part of the below code in Invite handler:
if (!proxy_authorize("","subscriber")) { proxy_challenge("","1"); break; } else if (!check_from()) { log (1,"route[3]: 403 error \n"); sl_send_reply("403", "Use From=ID"); break; };
Without the check and the fixed contact , no UA behind NAT could make a call except from the UA that took port 5060 on NAT.
I also found that in my config file when a caller was behind nat and was trying to make a pstn call , i called use_media_proxy twice. When i fixed that , the calls would go through ok and not get a 503 response. Can someone explain what exactly happened when i called the use_media_proxy twice and the calls were getting rejected?
Many thanks, Kyriakos
