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.
What is the advantage of
the G.729 CODEC?
G.729 is a CODEC that compress the digitized voice signal to transmit
phone calls using much lower bandwidth than the standard G.711
CODEC. The tradeoff is a reduction in voice quality compared to
uncompressed voice, but quite acceptable to many users.
