Translation Rules Explained

[GRANT3779]

Hi There,

I'm seeing the config below and not exactly sure what it is actually doing in "easy to understand" terms.  Could someone please help in understanding the rules / profiles below?

Thanks

voice translation-rule 10
 rule 1 /\(2..\)/ /5\1/
!
voice translation-rule 20
 rule 1 // /9/
!
voice translation-rule 30
 rule 1 /^9\(.*\)$/ /\1/
!
!
voice translation-profile incoming-voice
 translate calling 20
 translate called 10
!
voice translation-profile outgoing-voice
 translate called 30

In additon to Suresh words, you can always use "test voice translation-rule..." to see what exactly each of these examples do with your digits...

Hi Grant,

voice translation-rule 10
 rule 1 /\(2..\)/ /5\1/

This rule will be matched for the numbers beginning with 2. This will add 5 to the number.

For eg if the number is 2000, it will make it 52000

voice translation-rule 20
 rule 1 // /9/

This rule will add 9 in front of any number.

Eg : If the number is 55, it will translate the same to 955

voice translation-rule 30
 rule 1 /^9\(.*\)$/ /\1/

This rule will be applicable for numbers beginning with 9. This rule will strip 9 and the rest will be taken ahead.

Eg : If the number is 9555 the number after translation will be 555.

voice translation-profile incoming-voice
 translate calling 20
 translate called 10

This profile will translate the calling number as per translation-rule 20 and the called number as per translation-rule 10.

The rules have been explained above.

voice translation-profile outgoing-voice
 translate called 30

This profile will translate the called number as per translation-rule 30.

Post the same these profiles have to be applied in incoming or outgoing directions on the port/dial-peer.

According to the directions the calls will be taken care by the rules.

Just as a Tip, remember that each translation is delimited by a forward slash (/) and the backward slash (\) indicates a character.

/\(2..\)/ /5\1/
