This configuration note explains how to configure Mediatrix units in a PBX Remote Line
With VoIP, the distance limitation of extending copper wire from a PBX to a remote location is
no longer an issue. Small remote branch offices (SOHOs) can now have existing analog phones
installed at the remote site as analog extensions of the PBX system at the Main Office.
In this scenario, we consider that 4 extensions of the PBX need to be relocated to a remote
- when a PBX user/extension initiates a call to one of the four (4) extensions, the extensions
will ring on the remote site and vice versa:
- when one of the four (4) extensions on the remote site initiates a call, that call will be
routed to the PBX, as if it was a local extension.
Additionally, the remote site has their analog telephone devices connected to two FXS
The routes are configured on the FXO unit, and the FXS port, corresponding to a phone
extension, are configured on the FXS units.
