But in the given case the UAS sends a new reliable response with RSeq + 1 after the first one (RSeq=1) is acknowledged, so the UAC should send a PRACK, am I right? -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
