Hi Javier,
this is quite impossible to do - by sending re-INVITEs from a middle
point, you will break the CSEQ consistency between the end points.
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
