IP Telephony FAQ's:
When do you need an ATA?
An ATA, or Analog Telephone Adapter, is an interface device installed
between a regular analog telephone and a IP network. It contains
the CODECS that digitize and decode voice, a network interface
card, and circuitry to handle signaling. ATAs are also used to
provide VOIP phone service to single line telephones.
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.
