Mobile Extension - Callback to Cell Phone
Description
Callback to Cell Phone allows the user to make an incoming call to a system then hang up before the
system answers (like a one ring call), then the system calls back to the calling Cell Phone using a
pre-programmed number. The advantage is to reduce Cell Phone charges for calls on a mobile
extension system.
After receiving a call back on a Cell Phone, the user can call another extension or make an outgoing call
via the system using the mobile extension function.
Example
– Callback to Cell Phone
Conditions
Mobile Extension must be programmed for this feature to work.
In the Callback to Cell Phone feature set Program 15-22-04 to 1. If the Cell Phone user
continues to ring over the time set in Program 22-01-12, the system answers the call as a
normal Mobile Extension call.
Callback to Cell Phone will not proceed and no retry is made if all trunks are busy when
trying to callback.
Callback trunk routing follows Program 15-22-03 setting. When set 0 (Normal trunk access
code), ARS also can be used.
If Mobile Extension does not answer the Callback within time set in Program 20-01-16,
Callback will stop. If answered the within the Callback time, the user hears an extension
dial tone. A splash tone is not heard.
If the system receives a
“Disconnect” from the far end after a Callback is made, Callback
will stop.
When Calling party number is used, Callback follows the Program 21-19-01 outgoing call
setting of the Mobile Extension which made the outgoing call.
The Callback to Cell Phone feature is not supported when using an analog trunk.
