I agree. Hopefully the implementers know to leave some room for resubmits with higher cseqs. http://www1.ietf.org/mail-archive/web/sip/current/msg10905.html > Requests *within* a dialog may take values up to 2^32-1. > If the CSeq in a dialog establishing request happens to > be close to 2^31 then requests within the dialog will be > forced into the range above 2^31, so that must > be supported. I agree. Unfortunately some commonly deployed SIP phones didn't support it late 2004; maybe they support it now. http://www1.ietf.org/mail-archive/web/sip/current/msg10895.html _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
