configure voice-port connection plar

Private line automatic ringdown (PLAR) is an autodialing mechanism that permanently
associates a local voice interface with a far-end voice interface, allowing call completion to a
specific telephone number or PBX without dialing. When the calling telephone goes off-hook,
a predefined network dial peer is automatically matched, which sets up a call to the destination
telephone or PBX.
By using the connection plar command you can enhance your voice network to offer a
number of useful features including the following:
• Providing an off-premises extension (OPX) from a PBX, thus simulating direct
connections between FXS port users on a voice gateway and the PBX.
• Providing dial-tone from a remote PBX in order to offer toll-bypass functionality. Instead
of relying on the gateways in your voice network to provide dial-tone, you can employ
PLAR behavior to enable remote sites to behave as though they have a direct connection
to a PBX.
• Eliminating the need for user dialing, because both of the endpoints for the VoIP call are
statically configured.
• Connection PLAR behavior eliminates the need for user dialing, because both of the
endpoints for the VoIP call are statically configured.
In addition, connection PLAR behavior does not dedicate bandwidth to a call unless one or the
other of the privately associated endpoints goes off-hook.
Take the following items into consideration when planning to configure Connection PLAR
behavior on your VoIP network:
• Because Connection PLAR is a switched VoIP call (similar to a switched virtual circuit),
calls are set up and torn down as needed—bandwidth is taken up only when a call is
initiated.
• Connection PLAR will operate between any types of signaling endpoints—FXO, and FXS
— and between any combination of analog and digital interfaces.
