An address prefix could be any of the following, or combinations of the following:
■ The same numbers as the country code and area code (for example,
1 303
within the United States, or
011 44 71
to reach London, United
Kingdom).
■ The same numbers as the area code (NPA) and office code (for example,
614 555
).
■ The office code (NNX or NXX) if the remote system shares the same area
code (for example,
555
).
■ An alphanumeric code used as a mnemonic of a location or system (for
example,
CB
for Columbus).
■ An RNX code if the remote system is in a private network (for example,
8
).
■ The AMIS prefix for AMIS address ranges only (for example,
7
). If an AMIS
prefix is defined, it must precede any other characters subscribers must
dial in any other address prefixes defined for the AMIS address ranges.
■ A Message Delivery prefix to help subscribers distinguish between
Message Delivery messages and AMIS messages (for example,
6
). A
Message Delivery address prefix and AMIS prefix could be the same, or
two different prefixes could be used.
In addition to the address ranges that specify the digits that
subscribers
must
enter (those that begin with an AMIS prefix, if defined), the local system also
requires an address range that uniquely identifies the hunt group (callback
number) of the remote machine (this is the voice mail system number sent to the
local machine from the remote system when incoming AMIS messages arrive).
This address range is needed to identify this specific remote system to the local
system. If the remote machine has a different country code, this address range
must contain the complete callback number (country code, area/trunk code, and
hunt group). If the remote machine has a different area or trunk code, only the
area/trunk code and hunt group are needed (the country code should be
omitted). If the remote system is local, only the hunt group number should appear
for that machine. If the remote machine can be accessed through a private
network, the network-access code and hunt group for the remote machine
should appear in the address prefix list.
