Callback Feature; Table 78: Callback Configuration Parameters - Grandstream Networks UCM6206 User Manual

Callback is mainly designed for users who often use their mobile phones to make long distance or international
calls which may have high service charges. The callback feature provides an economic solution for reduce the
cost from this.
The callback feature works as follows:
1. Configure a new callback on the UCM6200.
2. On the UCM6200, configure destination of the inbound route for analog trunk to callback.
3. Save and apply the settings.
4. The user calls the PSTN number of the UCM6200 using the mobile phone, which goes to callback destination
as specified in the inbound route.
5. Once the user hears the ringback tone from the mobile phone, hang up the call on the mobile phone.
6. The UCM6200 will call back the user.
7. The user answers the call.
8. The call will be sent to DISA or IVR which directs the user to dial the destination number.
9. The user will be connected to the destination number.
In this way, the calls are placed and connected through trunks on the UCM6200 instead of to the mobile phone
directly. Therefore, the user will not be charged on mobile phone services for long distance or international calls.
To configure callback on the UCM6200, go to web GUI->PBX->Call Features->Callback page and click on
. Configuration parameters are listed in the following table.
