Remote Line Extension
The Remote Line Extension feature makes it possible to connect remote small offices with similar capabilities
as if they were located in the main or head office. Essential features such as integrated voicemail, unified
messaging, line extension dialing plans and many others can be offered to remote sites.
Mediatrix FXS access devices and Mediatrix 1204 FXO gateways extend PBX extensions to remote workers
located at SOHOs (Small Offices/Home Offices), using VoIP. PBX extensions are connected via Mediatrix
1204 FXO ports to the IP network, instead of being connected to individual stations. At the SOHO locations,
Mediatrix FXS units connect analog phones to the same IP network.

To configure Remote Line Extensions:
1. Set the Mediatrix 1204 lines to perform automatic calls to a pre-defined number as defined in
“Automatic Call” on page 255 .
This allows you to define a telephone number that is automatically dialed when seizing an FXO line.
You can thus redirect SCN calls to a specific IP number such as a telephone connected to a FXS
port of a Mediatrix FXS device.
2. If applicable, you can instruct the Mediatrix 1204 to wait until the called party answers the phone
before it picks up the SCN line. You can do so in the
fxoMIB by setting the
fxoWaitForCalleeToAnswerEnable variable to enable .
3. If applicable, define how the Mediatrix 1204 behaves when it receives an IP call in the
analogScnGwDialEnable variable.

Parameter Description
disable The Mediatrix 1204 picks up the SCN line and opens the audio channel
with the peer. This way, the user of a dedicated FXS/FXO combinaison will
feel “closer” to the SCN: as soon as the user takes the receiver off-hook,
he/she interacts with the SCN because the actions are not relayed via IP to
the FXO unit.
enable The Mediatrix 1204 picks up the SCN line and dials the telephone number
associated with the destination of the call before opening the audio channel
with the peer. This is the default value.
