Example dial plan

This page shows an example dial plan and explains how individual calls will match rules in the dial plan.

In the example, the IP gateway has registered a prefix of 98 with the gatekeeper. The IP gateway has been configured to apply the dial plan to numbers dialed in the auto attendant.

# Condition Action Description

0

Called number matches "980"

Call the operator

This rule forwards all calls to 980 to the operator.

1

Called number matches
"981 (D+) S (D+) S (D+) S (D+) S (D+)"

Call this number "$1 . $2 . $3 . $4 : $5"

This rule takes an IP address (with stars used to replace dots) combined with an extension number. For example, if a caller wants to dial extension 1234 on an unit with IP address 10.12.12.12, that caller will dial:
98110*12*12*12*1234

2

Called number matches
 "981 (D+) S (D+) S (D+) S (D+)"

Call this number "$1.$2.$3.$4"

This rule takes an IP address with stars (asterisks) used to replace dots, and converts it into a dot-separated IP address and calls that IP address.

3

Called number matches
"980 (D+)"

Call this number: 192.168.12.10:$1

This rule connects a caller to a service on and H.323 gateway. For example, where 192.168.12.10 is the IP address of an MCU, the caller can connect to a conference by dialing the conference ID.

In this rule, the caller dials 980 followed by the numeric ID of the conference they require on the MCU with the given IP address. In this example, the MCU has IP address 192.168.12.10.

4

Called number matches "982(D+)"

Call this number: $1

In this rule, the IP gateway dials the gatekeeper-registered E.164 number dialed by the caller. For example, a caller wanting to dial extension 1234 dials:
9821234

5

No called number

Enter the auto attendant "<menu name>"

Use of this rule in the dial plan controls the action for a call to the IP address or hostname of the IP gateway: With the action set to Enter the auto attendant <menu name> , all calls to the IP address/hostname will be connected to the named menu of the auto attendant.

6

Match any called number

Reject the call

This is a catch-all rule that will reject any call that does not match any of the above rules. In this example, it will prevent callers from dialing E.164 numbers in the auto attendant.

 

How the dial plan is applied to incoming calls

The following table shows which rule is matched when callers dial particular numbers. Note that the IP gateway will apply the dial plan that corresponds to the port on which the call arrived (dial plan A for calls arriving on Port A, dial plan B for calls arriving on Port B). The order of the rules is important. The IP gateway attempts to match an incoming call to a rule starting at the top of the list and works down until it finds a match. You can change the order of the rules by dragging and dropping or by using the up and down links on the right of the dial plan list.

5

Enter the auto attendant.

4

Call extension "7654"

7890

6

Call rejected.

9804444

3

Call "192.168.12.10!4444"
In this example, this connects the caller to conference 4444 on MCU with IP address 192.168.12.12
