Creates a set rules for rerouting calls to sets of phones that
are unavailable during Cisco Unified CM fallback.
•
tag
: Identifier for alias rule range. The range is from 1
to 50.
•
number-pattern
: Pattern to match the incoming
telephone number. This pattern may include wildcards.
•
to
: Connects the tag number pattern to the alternate
number.
•
alternate-number
: Alternate telephone number to
route incoming calls to match the number pattern. The
alternate number has to be a specific extension that
belongs to an IP phone that is actively registered on the
Cisco Unified SRST router. The alternate telephone
number can be used in multiple
alias
commands.
•
preference
preference-value
(Optional). Assigns a
dial-peer preference value to the alias. The preference
value of the associated dial peer is from 0 to 10. Use
with the
max-dn
command.
•
cfw
number
(Optional). The
cfw
keyword allows users
to set call forward busy and call forward no answer to
a set string and override globally configured call
forward settings.
•
timeout
timeout-value
(Optional). Sets the ring
no-answer timeout duration for call forwarding, in
seconds. Range is from 3 to 60000.
•
huntstop
(Optional). Stops call hunting after trying
the alternate number.
