This option is new for IP Office Basic Edition 6.1 and higher+. This settings can be used to change the destination for an extension's transfer return calls.
•The existing extension setting Transfer Return Rings sets whether and when calls transferred by an extension return to it. The Transfer Return Extension setting allows such calls to be redirected.
•Note that if a door phone or paging extension is selected, the call will continue ringing at the transfer destination rather than returning.
•When a call is routed to an extension by transfer return, it alerts with the Transfer Return ringing pattern. The display indicates both the transferred caller's details and the original transfer destination.
•If a phantom extension, door extension or paging extension is set as the transfer return destination, transferred calls will not follow transfer return and instead will continue ringing at the transfer destination.
•Calls transferred by an auto attendant are not subject to transfer return.
•When the transfer return extension has no available intercom buttons, the call will continue to alert at the original transfer destination until the transfer return extension becomes available at which time the transfer return will occur. This also applies for a busy analog extension or an extension in programming mode.
•When an external call follows transfer return and there is a line appearance for the call, it alerts on the line appearance. If there is no line appearance the call shall alert on an intercom button.
•When an internal call follows transfer return, it alerts on an intercom button.
•If a call is transferred to an extension which is the transfer return destination for the transferring extension, the call remains ringing at the transfer destination.
•Transfer return calls ignore Do Not Disturb, call forwarding, call coverage and coverage to voicemail.
•Transfer return calls that are answered at the return extension are not logged even if the Called ID log answered calls is set to Active.
