IP Telephony FAQ's:
What are the leading VoIP
protocols?
The most popular are H.323, the original protocol established
by the International Telecommunications Union, and SIP or Session
Initiation Protocol, a text base protocol that is greatly simplified
by the more multimedia capable H.323.
How is latency dealt with
in VoIP?
Latency means the time delay between transmission and reception
of a signal. Network traffic variations often result in latency
variations from packet to packet known as jitter. Jitter buffers
on the receiving end smooth out the variations to deliver a cleaner
voice signal.
