Considerations
The MERLIN MAIL Voice Messaging System cannot be
connected to a system in the Behind Switch mode.
The MERLIN MAIL Voice Messaging System is available in
2-port and 4-port configurations. Both models have four hours
of message storage capacity.
Only four ports on the same 012 basic telephone module can
be used simultaneously with the MERLIN MAIL Voice
Messaging System. When four ports are used for the MERLIN
MAIL Voice Messaging System, only one other port can be
connected to a telephone.
The size of a user's mailbox—that is, the number of minutes
of messages that a mailbox can hold—can be matched to
individual needs. A mailbox can be set up to hold a maximum
of 15 minutes of messages.
When users receive voice-mail messages, the message LEDs
on their telephones turn on, provided that a mailbox has been
assigned to each of those telephones.
All VMI loop-start ports should be programmed for "reliable"
far-end disconnect.
Callers who dial from rotary telephones cannot use the
features of the MERLIN MAIL Voice Messaging System and
should be directed to the system operator during business
hours.
Automated Attendant can answer calls immediately (Primary
Call Handling) or after a delay (Secondary Call Handling), for
example, when a call remains unanswered by the system
operator after a certain number of rings.
The system may need more touch-tone receivers if
Single-line telephone users do not get dial tone.
AVP or IVP AA fails to transfer calls.
Calls fail to ring or calls go to coverage prematurely.
