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.
Which CODECs support FAX?
G.711, the most universally installed CODEC, supports FAX because
it has no compression of the signal. A newer T.38 CODEC was designed
to transport FAX by coding the picture signal for transmission
as an image file, not digitizing the analog FAX machine signal.
T./38 is not as commonly available as G.711.
