Reply To: SIP&H.323

Saul Bejarano

That question is like going to a football game and ask what is the purpose of the ball in the middle of the field.
OK: H323 in one protocol
SIP is another protocol

SIP is a more stable protocol and newer, H323 is older and mostly accepted by any wholesale VOIP carrier, SIP mostly retail applications users that need to run behind NAT and things like that.
