@ -246,6 +247,9 @@ Call completion on subscriber busy (CCBS):
|
|||
If the remote party becomes 'non-busy', the network initiates the callback which will be
|
||||
sent to the provided context/exten/priority. Of course, this only happens if your local
|
||||
phone is set to 'free' with capicommand(ccpartybusy), which is the default.
|
||||
In this context/exten/priority you should just setup a callfile to initiate an outgoing
|

call from your extension to

exten => s,1,Dial(CAPI/ccbs/${CCLINKAGEID}/)

To deactivate a previously activated CCBS, use following command:
