Using rules, it is possible to limit the bandwidth available for incoming ISDN calls. This is useful where you want to limit

the network resources available to individual calls. In this way, you can prevent any one calls using the resources to the

extent that other incoming calls are prevented.

Forwarding ISDN Calls to an Operator or a Conference

The dial plan below forwards any calls from the ISDN network ending in 0000 to an operator and forwards any other

dialed number of four digits or more to the MCU to join a conference where the conference identifier is the last four

digits of the original dialed number.

The dial plan shown below is an ISDN to IP dial plan:

# Condition Action Call type Bandwidth Description

0 Called number

matches "D

+ 0000"

Call this

number

"10.2.1.10"

BONDING

384Kbps This rule catches any number

ending in 0000 and forwards it

to, for example an operator, at

10.2.1.10

1 Called number

matches "D

+(DDDD)"

Call this

number

"10.2.1.20 :

$1"

BONDING

384Kbps This rule catches any number of

four digits or more and tries to

join a conference on the MCU at

10.2.1.20 with the numeric

identifier that matches the last

four digits.

Specifying Voice-only IP Telephone Calls

Use the dial plan to specify how IP telephone calls (that is voice-only calls) will be forwarded to the ISDN network.

IP endpoints sometimes do not allow users to specify the type of call being made. The following dial plan shows that

users can be told the prefix to dial, should their call be a telephone call rather than a video and voice call.

The dial plan shown below is an IP to ISDN dial plan:

# Condition Action Call type Bandwidth Description

0 Called number

matches

"550 (D+)"

Call this

number "$1"

Telephone None This rule specifies a voice-only

call to any call with prefix 550.

The specified action means that

the dial plan removes the prefix

and dials the group of numbers

that match the digits

represented by "(D+)" in the

condition. For example, an

incoming call to "5504321" will

cause an outgoing voice-only

call to be placed to "4321".
