Multiple Connections on Endpoints (Lines)
The Mediatrix 4100 supports multiple connections on one endpoint. Under MGCP, it is now possible to create
multiple connections on a single endpoint, as long as there is only one active connection at a time.
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 4100 allows you to set the minimum and maximum time within which pressing and releasing the
plunger is actually considered a flash hook.
 To set flash hook parameters:
1. In the fxsMIB, set the following variables:
2. Restart the Mediatrix 4100 so that the changes may take effect.
