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 Does VAD Work?
VAD, or Voice Activity Detection, is a technique that reduces
bandwidth in VoIP telephone systems by listening for the silence
in normal conversations and not transmitting any packets during
these periods.
