I thought transaction identifier is via:branch. is it dialog id you are referring to? Stateless is ok because for Dirty Invite you would receive ACK after you send a 4xx. And you can safely drop it.
From: Chrisil Joseph Arackaparambil<[EMAIL PROTECTED]> To: [email protected] Subject: [Sip-implementors] Malformed transaction identifiers Date: Wed, 21 Jun 2006 17:41:12 +0530 Hi, The Call-ID, To, From alongwith the CSeq headers are used as transaction identifiers. Now, if a request arrives with one of these headers as malformed or missing, what is the best way to handle and respond to the request? Even if we are able to manage to send a 400 Bad Request response, it will be difficult to maintain the transaction state. Should we handle the request statelessly in this case? Then it might not be possible to respond correctly to retransmissions of the request.
