CALLBACKFEATURE
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. 
Table 73: Callback Configuration Parameters 
Name  Configure a name to identify the Callback. 
CallerID Pattern 
Configure the pattern of the callers allowed to use this callback. The caller 
who places the inbound call needs to have the callerID match this pattern 
so that the caller can get callback after hanging up the call. 
Note: 
If leaving as blank, all numbers are allowed to use this callback. 
Outbound Prepend 
Configure the prepend digits to be added at before dialing the outside 
number. The number with prepended digits will be used to match the 
outbound route. ‘-’ is the connection character which will be ignored.
