Mobile Extension - Callback to Mobile Phone
Description
Callback to Mobile 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 Mobile Phone using
a pre-programmed number. The advantage is to reduce Mobile Phone charges for calls on a mobile
extension system.
After receiving a call back on a Mobile Phone, the user can call another extension or make an outgoing
call via the system using the mobile extension function.
Conditions
•
Mobile Extension must be programmed for this feature to work.
•
In the Callback to Mobile Phone feature set Program 15-22-04 to 1. If the Mobile Phone user contin-
ues to ring over the time set in Program 22-01-12, the system answers the call as a normal Mobile
Extension call.
•
Callback to Mobile 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 Mobile Phone feature is not supported when using an analog trunk.
•
If Flexible ringing is set, the Callback to Mobile Phone feature works in any type of Program 22-02-01
trunk setting. If Flexible ringing is not set, the Callback to Mobile Phone feature does not work if the
incoming call type is “DID/DISA”.
•
After answering Callback, if the system does not receive a DTMF signal from the Mobile Extension
using Program 20-18-01 (Default; 30 seconds), the system disconnects the call.
•
The trunk user for SMDR for Callback is tied to the extension number of Mobile Extension.
•
If the user calls a Mobile Extension port during while using the Callback to Mobile Phone feature, the
caller hears a busy tone.
