RE-INVITE<BR>><BR>> Hi
Javier,<BR>><BR>> this is quite impossible to do
- by sending re-INVITEs from a middle<BR>> point,
you will break the CSEQ consistency between the end
points.<BR>> Within the dialog, the cseq must
increase from message to message<BR>> -
if<BR>> you send a re-invite to point A with cseq
n+1, after a while point<BR>> B
may<BR>> sent a request with the same cseq since it
was not aware that some<BR>>
party<BR>> in the middle changed the
number.<BR>><BR>> the best way to do it is if
you have a end2end keepalive mechanism as<BR>>
Session-Timer.<BR>><BR>>
regards,<BR>>
