VOIP Protocols and Standards.pdf

sztt400

This paper first discusses the key issues that inhibit Voice over IP (VOIP) to be popular with the users. Then I discuss the
protocols and standards that exist today and are required to make the VOIP products from different vendors to
interoperate. The main focus is on H.323 and SIP (Session Initiation Protocol), which are the signaling protocols. We also
discuss some hardware standards for internet telephony.
