VOICE STORE AND FORWARD IN MOBILE RADIOS

by Motty Shor

  The ability to place or receive phone calls on a radio unit is offered on all Motorola Trunked radio systems. Three types of phone calls can be implemented on a trunked radio system:

* Individual mobile to landline.

* Landline to individual mobile.

+ Landline to talkgroup.

  When a phone call is initiated from landliie to a mobile, there are cases that the driver can't answer the phone call because he is busy driving the vehicle, or it is not safe to answer the call, or simply the driver is not in

to lose the phone call.

  In order to overcome this problem, a voice storage and forward capability can be added to the mobile radio. To implement this feature, an automatic answering machine is connected to the mobile radio via a special adapter. See FIG. 1.

  If the driver doesn't answer the incoming phone rings within a specitied time, the automatic answering machine will "answer" the call and record the message. The record- ing is stopped automatically when the phone call is ter- minated by the landliie (VOX activated).

Now the driver does not lose any phone calls and the vehicle at that time. All these cases cause the driver can respond to them when possible.
