I don't understant what you mean. When user A sends a MESSAGE to user B, the MESSAGE arrives to user B SIP phone. If the phone allows MESSAGE it will display it to the user and reply with: SIP/2.0 200 OK There is absolutelly no way of knowing if the user is in fact in front of the PC or if he has read the MESSAGE (maybe he's sleeping XDD). Maybe you answer about MESSAGE storaging, this occurs when user A sens a MESSAGE to user B, and proxy of user B know the user is not registered so it accepts the MESSAGE and stores it, but in this case proxy should reply with: SIP/2.0 202 Accepted This 202 should warn user A about him MESSAGE has been stored and will be delivered to user B later.
