Limitations when a Recording is Started by an Outbound Route
Important Warning! When a call recording is started by an outbound route, it is not possible for the recording service to bind to the call, and can only bind to the extension that started the recording (This is a limitation of Asterisk, and is resolved in Asterisk 13). This means that if you transfer the call, the recording will stop. Make sure that you transfer the call to a destination that has call recording set to Yes or Force, to re-establish the recording.
