Javier,
I guess the RFC3261 or google (SIP + reINVITE) are the best source for looking into.

Within the dialog, the cseq must increase from message to message - if you send a re-invite to point A with cseq n+1, after a while point B may sent a request with the same cseq since it was not aware that some party in the middle changed the number. the best way to do it is if you have a end2end keepalive mechanism as Session-Timer. regards, bogdan Javier Ramirez wrote: > Hi ! > I looking for a mechanism to keep alive, and I see that is used the > RE-INVITE, but > How to use the Re-INVITE to a keep alive mechanism ? > exist another way to implement another keep alive mechanism ? > > best regards > Javier ramirez > >------------------------------------------------------------------------ > >_______________________________________________ >Users mailing list >Users@openser.org >http://openser.org/cgi-bin/mailman/listinfo/users > > __________ NOD32 1.1586 (20060608) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com

Javier,
reInvites would have to be generated by some dialog stateful component of the call.
Depending on your network setup, this could be either endpoints or some B2BUA in the middle.
openSER is not dialog stateful (openSER is transaction stateful ) and thusly cannot generate reInvites.
Hope this helps
T.R.

Tan simple como poner un timer en cada llamada para que a los 30 segundos mande un INVITE igual al primero. Hubiera preferido una respuesta de: "no se como hacerlo" yo solo queria saber si se podia hacer con el openser, es decir, si el openser ya lo tenia ! no era tan dificil la pregunta saludos Javier
