Voice Technology Basics
Voice - Capable Route
A voice-capable router can replace a Private
Line, Automatic Ringdown (PLAR) service from a telephone service
provider.
In the example, a user takes the phone off-hook,
causing another telephone extension to ring. The voice-capable
router recognizes that the phone is off-hook, and routes the
call over an ATM, Frame Relay, or HDLC network to the remote
router. The remote router then routes the call to the PBX,
which rings the appropriate extension. This solution eliminates
the need for dedicated PLAR lines.
Tie Trunk Replacement PBX to PBX
Voice-capable routers on a WAN can replace
tie trunks between remote locations, thereby saving the cost
of tie trunks. In essence, the voice-capable router on either
side of the ATM, Frame Relay, or HDLC WAN connection is configured
as a tie trunk. The router then routes incoming and outgoing
calls through the PBX.
