That has NOTHING to do with rport. XMPP is a whole lot simpler than SIP. Try doing call transfer, redundancy, fail over, load balancing etc with xmpp. XMPP is good for IM and simple point to point voice calls (jingle). SIP is simply over engineered for point to point instant messaging and presence - like shooting a fly with a cannon. The only reason to use SIP for such things as presence is if you are already using it for multimedia. > > Let's explain to a new SIP developer that in case of SIP TCP the reply > must go to the real source ip:port, in case of UDP is depends on if > "rport" is present or not, then take a look to Via header, take the > host but not the port... and all that stuf, and there will become a > new XMPP developer. > > Anyway I understand what you say, but AFAIK aysimmetrical SIP devices > are not common today, are they? > > Best regards. > > -- > Iñaki Baz Castillo > <[EMAIL PROTECTED]> > > _______________________________________________ > Sip-implementors mailing list > [email protected] > https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors -- M.
