Syntax for actions (Call this number)
When you configure the
Action
for a dial plan rule, you may want to specify a pattern for the number to
call, rather than specifying any of: call original called number, reject the call, or the exact number to call.
The table below describes the syntax you can use to express a pattern for the
Call this number
field in the
action of a rule:
Syntax
Field description
Example
Letters and
numbers for
address
To call a specific number (or for ISDN to
IP calls, you can also specify an IP
address, hostname, or H.323 URI), type
that number (or IP address, hostname, or
H.323 URI).
Example: to specify that when this rule is
invoked, the MCU with hostname my_mcu
is called, type
my_mcu.
Example: Suppose the domain “
cisco.com” has a H.323 service (SRV)
record set up. To call a H.323 video
endpoint residing in that domain, e.g. with
URI [email protected], set an
action to call
. For
information about domain (DNS) SRV
records, see RFC 2782.
:
To call a specific extension, separate the
number/address from the extension by
typing a colon (
:
).
Example: to call the Cisco TelePresence
MCU with IP "10.2.1.33", and try to join a
conference with numeric identifier "00000",
type
10.2.1.33 : 00000.
!
To call a specific extension, separate the
number/address from the extension by
typing an exclamation mark
(!)
.
Example: to call the Cisco TelePresence
MCU with IP "10.2.1.33", and try to join a
conference with numeric identifier "00000",
type
10.2.1.33 ! 00000.
$
To include any of the digits from the
incoming called number in the outgoing
number, specify a substitution, by typing
the dollar sign ($), followed by a index.
Valid indices are:
A
: substitute the entire incoming called
number.
1 to 9
: substitute the digits enclosed in
the nth set of parentheses of the
condition.
Example: for all calls matching the
condition of "55 (DDDD)", set an action to
call the MCU with name "my_mcu" and join
the call to the conference with identifier that
matches "(DDDD)". For this example, type
the action of
my_mcu ! 00 $1
. In this case,
an incoming call to "551234" will attempt to
join conference with numeric identifier
"001234" on the Cisco TelePresence MCU
with the name "my_mcu".
Note that if the substitution creates an
empty number, the call will be rejected; in
the above example, an incoming call to 55
would result in an empty substitution.
