Programming Extensions
You must assign a specific extension type to each extension in the MERLIN Messaging System
to assure the enforcement of transfer restrictions and to designate transfer destinations (that is, to
a mailbox, Automated Attendant, fax or system extension).
There are four possible extension types:
●   Mailbox
●   Transfer-Only
●   Automated Attendant
●   Fax
Programming an extension also requires you to identify the phone status for the extension. The
phone status for an extension affects the way that a call is routed within the MERLIN Messaging
System when the caller requests to be transfered to that extension, as illustrated below:
Telephone? Call Handling Outcome
Yes
Incoming calls are transferred by the
MERLIN Messaging System to the
applicable extension
Calls are transferred to the extension
No
Incoming calls transferred by the
MERLIN Messaging System stay in
the MERLIN Messaging System
Calls are routed directly to Call Answer
Service or Automated Attendant Service
for the extension
Note: Transfer-Only and Fax extensions always have a telephone associated with the extension.
Refer to MERLIN Messaging System Planning Form 2 – Extension Administration for
information that applies to your system.
