Voice Translation Rule is a key part in the Voice Gateways which helps you to translate the Calling Number, Called Number and the

Plan type customized for your customers / partners while sending or recieving calls in the gateway.

This document helps you to create the Voice Translation Rules for configuring the Calling and Called Dial patterns and plans specific for

National and International dialing plans. There are examples given for changing the Number type and plan and Rejecting calls.

Example 1

This example replaces the first occurrence of the number "123" with "456".

voice translation−rule 1

rule 1 /123/ /456/

These are test voice translation−rule examples:

router#test voice translation−rule 1 123

Matched with rule 1

Original number: 123 Translated number: 456

router#test voice translation−rule 1 1234

Matched with rule 1

Original number: 1234 Translated number: 4564

router#test voice translation−rule 1 6123

Matched with rule 1

Original number: 6123 Translated number: 6456

router#test voice translation−rule 1 6123123

Matched with rule 1

Original number: 6123123 Translated number: 6456123

Original number type: none Translated number type: none

Original number plan: none Translated number plan: none

In this example, the rule matches the first occurrence of the number that contains the pattern "123" anywhere

in the number. Specifically, you can use the start and end of number indicators. The Example 2 and Example

3 sections show this.

Example 2

This example shows how to replace any occurrence of "123" at the start of a number with "456".

voice translation−rule 1

rule 1 /^123/ /456/

These are test voice translation−rule examples.

router#test voice translation−rule 1 123

Matched with rule 1

Original number: 123 Translated number: 456

router#test voice translation−rule 1 1234

Matched with rule 1

Original number: 1234 Translated number: 4564

router#test voice translation−rule 1 6123

6123 Didn't match with any of rules

Example 3

If you want only the match of an exact number, specify both the start and end number indicators:

voice translation−rule 1

rule 1 /^123$/ /456/

router#test voice translation−rule 1 123

Matched with rule 1

Original number: 123 Translated number: 456

router#test voice translation−rule 1 1234

1234 Didn't match with any of rules

router#test voice translation−rule 1 6123

6123 Didn't match with any of rules

Example 4

This example replaces all numbers with "5554000".

voice translation−rule 2

rule 1 /.*/ /5554000/

router#test voice translation−rule 2 123

Matched with rule 1

Original number: 123 Translated number: 5554000

router#test voice translation−rule 2 86573

Matched with rule 1

Original number: 86573 Translated number: 5554000

router#test voice translation−rule 2 ""

Matched with rule 1

Original number: Translated number: 5554000

Example 5

This example replaces any number that starts with a combination of zeros (0, 00, and so forth) with "909".

voice translation−rule 5

rule 1 /^0+/ /909/

router#test voice translation−rule 5 0123456

Matched with rule 1

Original number: 0123456 Translated number: 909123456

router#test voice translation−rule 5 00123456

Matched with rule 1

Original number: 00123456 Translated number: 909123456

NUMBER TYPE AND PLAN TRANSLATION

Example 1

In this example, if a number starts with "4" and the type is "national", the rule adds "90" as a prefix. If the

type is "international", the rule adds "900" as the prefix.

voice translation−rule 7

rule 1 /^4/ /904/ type national national

rule 2 /^4/ /9004/ type international international

router#test voice translation−rule 7 493456567 type national

Matched with rule 1

Original number: 493456567 Translated number: 90493456567

Original number type: national Translated number type: national

Original number plan: none Translated number plan: none

router#test voice translation−rule 7 493456567 type international

Matched with rule 2

Original number: 493456567 Translated number: 900493456567

Original number type: international Translated number type: international

Original number plan: none Translated number plan: none

This is useful when telephone companies (Telcos) remove access codes on national and international

numbers. You can add the correct prefix with the number type as a basis.

Example 2

This example changes the number type and plan.

voice translation−rule 8

rule 1 /^2\(...$\)/ /01779345\1/ type unknown national plan unknown isdn

This rule matches any four−digit number that starts with "2". The rule removes the "2", adds the number

"01779345" as a prefix, and sets the plan to "isdn" and the type to "national".

router#test voice translation−rule 8 2001 type unknown plan unknown

Matched with rule 1

Original number: 2001 Translated number: 01779345001

Original number type: unknown Translated number type: national

Original number plan: unknown Translated number plan: isdn

Reject Calls

Use the reject keyword to reject calls that match. This example rejects all calls that start with "234".

rule 1 reject /^234/

router#test voice translation−rule 10 1234

1234 Didn't match with any of rules

router#test voice translation−rule 10 2345

blocked on rule 1

Thanks.
