Hi Andrea ACK is only sent in response to response of INVITE request.
Same can be referred from section 4 of RFC 3261 which mentions "Alice confirms receipt of the BYE with a 200 (OK) response, which terminates the session and the BYE transaction. No ACK is sent - an ACK is only sent in response to a response to an INVITE request." regards Abhishek Dhammawat Aricent ________________________________________ From: sip-implementors-boun...@lists.cs.columbia.edu [sip-implementors-boun...@lists.cs.columbia.edu] On Behalf Of Andrea [fuffa...@gmail.com] Sent: Friday, October 09, 2009 11:05 PM To: sip-implementors@lists.cs.columbia.edu Subject: [Sip-implementors] ACK to a 500 internal server error (info) Hello list, I would like to know if the response 500 Internal Server Error to a INFO msg need to be ACKnoledge.
