Configuring a Call Routing Rule
A Call Routing Rule is a special dial plan that specifies the lines that can be used to
transmit a dialed number. The same number pattern can apply to more than one
line.
SYNTAX:
( <:Lw,x,y,z>number-pattern |
<:Lw,x,y,z>number-pattern |
<:Lw,x,y,z>number-pattern |
<:Lw,x,y,z>number-pattern )
• L: A signifier for “Line”
• w, x, y, z: The number of the line interface (L1 for Line 1, L2 for Line 2, and so on)
• port: The port number
NOTE This parameter applies only if the line interface is configured for a SPA400.
• number-pattern: The dialed sequence that can use the specified lines
• Other elements:
• Enclose the entire call routing rule in parentheses.
• Use a comma to separate each digit sequence within a number-pattern.
• Use a pipe character (|) to separate each call routing rule.
NOTE The Call Routing rules use the same digit sequences as the Dial Plan rules. See
“Digit Sequences,” on page 66.
• Allowing any line interface to be used
EXAMPLE: (<:L1,2,3,4>9xx.)
Any line interface can be used for any dialed sequence that begins with 9 and
includes at least two additional numbers. The SPA9000 chooses an available
line from the list, proceeding in the listed order. See “Line Availability,” on
page 78.
