Hi, thanks for reply my email. I made the following test: I sent five different messages: one two three four five and I traced the SIP traffic passing through the server. They were stored in the DB in the correct sequence. So far so good. Now comes the problem, I saw the IM going out from my SIP Server and the sequence was wrong: three five two four one And exactly in that way appeared the IM in my client when the user went online. In my opinion the IM were not properly sent when they went out from OpenSER Cheers, Cesar -----Ursprüngliche Nachricht----- Von: Daniel-Constantin Mierla [mailto:daniel@voice-system.ro] Gesendet: Donnerstag, 04.

Because they are sent in a very short time frame, maybe the get in a different order to the user, because of network transmission. Can you watch the sip traffic sent by proxy?
