Greetings, Scenario: Call reaches extension A. A blind transfers the call to extension B. B is busy (on another call). Call needs to transfer back to extension A. Currently, calls go to voicemail when transferred to a busy extension. We are using v15.5. Under Settings>PBX>Transfer Back on Busy, we have DialCode: *3* (default, not being used for any other dial codes), and under Timeout I have set 10. I cant seem to get this working though. Any thoughts?
