Bandwidth

The maximum ISDN bandwidth that will be

used for the call if this rule is invoked.

The value will be one of:

● Telephone: meaning that the call

will be restricted to voice-only.

● Number of Kbps: the maximum

bandwidth allowed for calls

matching this rule.

● <default>: meaning that the

default maximum bandwidth

setting is used. To configure the

default bandwidth go to Home >

Settings > ISDN

● N x 64kbps: meaning that the call

is a video call using N x 64 kbps

(for legacy ISDN endpoints only).

Port

For IP to ISDN only: The ISDN port on which

the call will be placed.

This is an optional setting. The default value

is <any>. However, you may set a port if

required. For example, you may decide to

have all incoming ISDN calls on one port and

all outgoing ISDN calls on another port.

* (asterisk)

Identifies the rule you have just added. If you have just added or moved a rule in

the list, it will be marked with an asterisk

(*). This is to help you see the chnages you

have made.

Move

Use "Up" and "Down" to re-order the rules

within the list.

Remember that the ISDN gateway checks

calls against the dial plan starting at the top

of the list of rules. The first rule to match the

condition of the call will be invoked. Place

rules with specific conditions at the top of

the list. Place rules with general conditions

(for example, Match any called number)

at the bottom of the list.

Modifying the Rules List

To change the order of rules, use the up and down links.

To add a rule, click Add rule (see

Adding and Updating Dial Plan Rules).

To remove a rule, select one (or more) and click Delete selected rules.

Testing the Dial Plan

It may take some experimentation to create the dial plan that you require. The ISDN gateway provides a facility so that

you can test the dial plan to see how your set of rules acts on a particular number.

To test the dial plan:

1. Go to Home > Dial plan.

2. If you want to test how the dial plan acts

❍ on a particular number or address for an ISDN to IP connection, ensure you are on the ISDN to IP

dial plan tab.

❍ on a particular number for an IP to ISDN connection, ensure you are on the IP to ISDN dial plan

tab.

3. In the Test dial plan section, enter the number to test and click Test number.

The ISDN gateway displays the number that you have tested, the rule that the condition matched, the outcome (that is,

whether the call was rejected or the number that has been dialed in response), and the bandwidth used.
