Do you mean that you are interested in a re-INVITE to happen even if it's not required according to ICE specification? > Also, why not send a > re-INVITE allways, so that the middleboxes now the state in any case, > instead of guessing by the absence of the re-INVITE? Because SIP is end-to-end by design, so theorically there are no middleboxes handling the media. If you want such re-INVITE to occur, then the SIP proxy should rewrite the entire SDP (also the ICE part) to force such re-INVITE, but this is obviously a hack. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
