Permanent Administrative State
The permanent administrative state is applied every time the Mediatrix 4104 restarts.

To set a permanent administrative state:
1. In the ifAdminMIB , locate the ifAdminInitialAdminState variable.
This variable indicates the administrative state the current analog line will have after the Mediatrix
4104 restarts. It offers the following settings:
Unregistered Line Behaviour
You can specify whether a line should remain enabled or not when not registered. This is useful if you want
your users to be able to make calls even if the line is not registered with the SIP server.
This feature is currently located under the mediatrixExperimental branch of the MIB structure. See “MIB
Structure” on page 133 for more details.

To specify unregistered line behaviour:
1. In the sipExperimentalMIB , locate the sipUnregisteredPortBehavior variable.
The following values are available:
Flash Hook Detection
The flash hook can be described as quickly depressing and releasing the plunger in or the actual handset-
cradle to create a signal indicating a change in the current telephone session. Services such as picking up a
call waiting, second call, call on hold, and conference are triggered by the use of the flash hook.
A flash hook is detected when the hook switch is pressed for a shorter time than would be required to be
interpreted as a hang-up.
Using the “flash” button that is present on many standard telephone handsets can also trigger a flash hook.
The Mediatrix 4104 allows you to set the minimum and maximum time within which pressing and releasing the
plunger is actually considered a flash hook.

Setting Description
unlocked Registers the line to the SIP server.
locked The analog line is unavailable for normal operation. It cannot be used to
make and/or receive calls.
Table 137: Unregistered Line Behaviour
Value Description
disablePort When the line is not registered, it is disabled. The user cannot make or
receive calls. Picking up the handset yields a fast busy tone, and incoming
INVITEs receive a “403 Forbidden” response.
enablePort When the line is not registered, it is still enabled. The user can receive and
initiate outgoing calls. Note that because the line is not registered to a
registrar, its public address is not available to the outside world; the line will
most likely be unreachable except through direct IP calling.
