Call Back
When the user is in National / International roaming, it is expensive to make outgoing calls. In such cases a
Callback request can be made by the user on the Mobile port of the system. The system will automatically initiate
the call to the user. This helps the organisation to reduce roaming cost.
How it works?
User A wants to call User B using Callback.
• You need to enable ‘Callback’ and program the Callback Table. The Callback table has two parameters,
namely:
• Calling Number: It is the number of the caller who makes a Callback request. In this case, User A.
• Destination Number: It is the final called party number. In this case, User B.
• User A initiates a Callback call on the Mobile Port.
• The system checks the CLI of User A with the Calling Numbers programmed in the Callback Table.
• A match is found, the system rejects the call.
• The system calls back User A.
• User A answers the call. The system checks for a corresponmding Destination Number (User B) in the
Callback Table.
• A match is found, system dials out User B’s number.
• User B asnwers the call.
• Speech between User A and User B.
• If User B’s number is not programmed as the Destination Number, the system provides dial tone to User A,
when User A answers the call.
• This feature functions only:
•
When the set system mode is set to ‘Mobile-FXO’;
• When CLI is received for the incoming call.
• If the system dials out the callback number and the call is not matured due to any reason, the system
treats the callback request as served. It will not retry callback.
• Callback request will be served only when Mobile Port is idle.
How to Program?
• Use following command to disable/enable ‘Callback’ feature:
