RE: [Sip] about H.323 and SIP

Henry,

Hey, what is this, guilt by association? :-) Yes, _they_ are circuit
switched, but H.323 and SIP are 100% packet switched, so I don't understand
what your point is here. Moreover, both H.323 and SIP are based on
technology from the same era--right about 1990--including the WWW, HTML,
ISDN, and H.320, so they are equally "old style."

BTW, I apologize for the "propaganda" remark. Those three cups of coffee
this morning kinda jazzed me up a bit. 8-}

H.323 is part of the H.3xx suite and was developed to be compatible with
H.321, H.322, H324 - ISDN, ATM and POTS - all are circuit switched,
propaganda or not.

Its architecture has certainly started with ISDN multimedia.
