IP Telephony FAQ's:
What is the function of
a voice gateway?
Voice gateways are network hardware devices that provide the interface
between the enterprise LAN and the public switched telephone network.
This involved converting between packet based VoIP telephony and
circuit switched based TDM telephone trunks or analog telephone
lines.
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.
