[SIPForum-discussion] Stateless Proxy and TCP transport

[Victor Tsoukanov]

When stateless proxy forwards request with TCP it should open new client connection and send message. In accordance with RFC 3261 "....For reliable transports, the response is normally sent on the connection on which the request was received. Therefore, the client transport MUST be prepared to receive the response on the same connection used to send the request."  As I understand it means that request and following resnpose/resnposes can be send on the same connection. Again from RFC 3261 ".... a SIP transaction consists of a single request and any responses to that request, which include zero or more provisional responses and one or more final responses." From this point I am able to conclude that the client connection should be opend during SIP transaction. If "... A stateless proxy does not have any notion of a transaction" how can I provide such behavior ?
