Getting Ready for VOIP - Don\'t Get Caught in the Asynchronous Transcoding Chasm

There is critical need to understand all the new terms related to VoIP as well as international standards, CODECs, SIP-RTP emerging technologies and new VOIP services.

    / - February 21, 2005 - VOIP-Voice Over Internet Protocol is the next "killer application." By integrating different "box" platforms, protocols, applications and wiring, the promise of unified messaging may finally emerge. However, aside from the issues of incompatible telephone sets, LAN switches upgrades, CAT3 to CAT5 wiring upgrades, media gateways from IP networks to the PSTN for off-net calls, there is critical need to understand all the new terms, international standards, CODECs, SIP-RTP and other protocols, emerging technologies and new VOIP services.

As Matt Jolly of Revnets warned, "is it really worth putting mission-critical services on one wire in one pipe on one network just to save a few dollars. Adding voice to data networks is even more complex than adding email to the network and who foresaw the billions of unanticipated spam and viruses we now get?
