extension B finishes the call, IP PBX will ring extension B within a minute. When extension B is picked
up, IP PBX will ring extension A to connect the call. Extension A call also press * to cancel, and will
connect to voice mail.
Note:
The IP Phone should disable call waiting (multi-line) function in order to activate the line-in-use
call back function. If the extension B does not disable the call waiting function on IP Phone,
when extension A calls to extension, and extension B is in use, the second line of extension B’s
IP Phone will ring.
For transfer-call-back function, extension A calls to extension B, extension B (transferer) tries to
transfer the call to extension C (transferee). After the transferee’s unavailable timeout reached,
extension B gets re-ringback tone from IP PBX.
Note:
To trigger the transfer-call-back-to function, all of the following conditions must be true:
1. It is phone-based ring-transfer.
2. The transferee is a local extension.
3. The transferee does not answer until the unavailable timeout is reached.
4. No forwarding settings to voicemail/extension for the transferee.
