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: substitute the digits enclosed in the first set of parentheses of the condition.

2: substitute the digits enclosed in the second set of parentheses of the condition.

3: substitute the digits enclosed in the third set of parentheses of the condition.

4: substitute the digits enclosed in the fourth set of parentheses.

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 Codian MCU with the name "my_mcu".

❍ Call these numbers: this option only becomes available if you select Video using n x 64kbps

(legacy) as the call type (for IP to ISDN calls) in the Additional parameters section. Only use

Video using n x 64kbps (legacy) if you are supporting legacy ISDN endpoints that need this feature.

You must ensure you enter the correct number of telephone numbers. For example, if you select 3 x

64kbps as the call bandwidth, you must enter three telephone numbers here. Note that you must

enter the actual numbers, rather than using any substitutions.

5. Configure additional parameters, if required:

❍ Call type: Specify the type of outgoing call from:

■ Telephone: if the call is a voice-only telephone call.

■ Video using BONDING (default): a "typical" video call.

■ Video using N x 64kbps (legacy): only select this if you need to support legacy ISDN

endpoints that require n x 64kbps channels. This option is only available for IP to ISDN

calls

❍ Call bandwidth: optionally, select a maximum bandwidth for the ISDN part of the call, which will

otherwise be set to the default value. To view or edit the default value, go to Home > Settings >

ISDN. The maximum bandwidth settings on the Home > Settings > ISDN page are global

settings. Therefore, if you choose a greater setting in the dial plan than you have as a global

setting, the global setting will be used as the maximum value. For example, if in the dial plan you

choose to set 320kbps (5 x B channels) as the maximum bandwidth and the global setting for

maximum bandwidth for outgoing ISDN calls is 256kbps (4 x B channels), the maximum

bandwidth available to the call will never be more than 256kbps.

Note that if you have selected Telephone as the call type, this option is unavailable.

Note that if you have selected Video using n x 64kbps (legacy) as the call type, you must ensure

you select a bandwidth that matches the number of telephone numbers that you have entered.

❍ Place call on: optionally, select the ISDN port on which the call will be placed. For example, you

may decide to have all incoming ISDN calls on one port and all outgoing ISDN calls on another port.

6. Click Add rule.

Updating Dial Plan Rules

To update an existing dial plan rule:

1. Go to Home > Dial Plan and find the rule you want to modify (either in the IP to ISDN dial plan or in the

ISDN to IP dial plan, depending on to which dial plan the rule belongs).

2. Click on the number of the rule to view and modify rule details.

3. Use the information listed above in

Adding Dial Plan Rules to help you update the rule.
