PBX Remote Line Extension
This configuration note explains how to configure Mediatrix units in a PBX Remote Line Extension scenario.
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.
- 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.
The routes are configured on the FXO unit, and the FXS port, corresponding to a phone extension, are configured on the FXS units.
