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
