Description

With this service, a caller attempting to reach a busy extension can instruct the PBX to call them back once the other party is available. This service is exclusive to extensions calling other extensions.

If a user wishes to use this service, they must dial the CCBS code (disabled by default) within 20 seconds of the end of the call. KalliopePBX will confirm by playing the "Saved" audio file. When the busy user is free, the PBX will call the user who activated the service (their phone display will show the label c2c followed by the number of the extension they originally called), and once they answer, they will make the call to the other user.

If the user wishes to cancel the service, they must dial the CCBS cancel code (disabled by default). KalliopePBX will confirm by playing the "Saved" audio file.

This service is valid for one hour. If the service is activated again before the previous activation expires, the old one will be automatically canceled (only one instance can be active per extension).

Configuration

The service can be enabled/disabled in the PBX -> Numbering plan page.

The service code can be changed in the PBX -> Numbering plan page.

Interoperability

When using the CCBS service, it may be useful to set a function key to activate a subscription and one to cancel it. This can be done by setting a Speed Dial key with the respective service codes as values.
