CCME Digit manipulation

 

CCME have several method to perform digit manipulation. It depends on the actual requirement you wish to accomplish to choose the appropriate method.

Here is the list:

1. exp-num (Global)
2. digit-strip (POTS)
3. translation-profile (VoIP & POTS)
4. prefix (POTS)
5. forward-digit (POTS)

If multiple of digit manipulation methods is applied, they are executed as the order shown above. So be careful when you mix them together.

 

Translation profile configuration example:

Configuration of voice translation profile is divided into 2 parts.

1. create voice translation-rules and associate them to voice translation-profile with appropriated target (calling or called number)

Router(config)# voice translation-rule rule number
Router(cfg-translation-rule)# rule 1 /match/ /set/
Router(cfg-translation-rule)# rule 2 /match/ /set/
Router(cfg-translation-rule)# rule 3 /match/ /set/ ...and so on

Router(config)# voice translation-profile CHANGE_DID
Router(cfg-translation-profile)# translate ?
called           Translation rule for the called-number
calling          Translation rule for the calling-number
redirect-called  Translation rule for the redirect-number
redirect-target  Translation rule for the redirect-target
Router(cfg-translation-profile)# translate called ?
<1-2147483647>  Translation rule tag
Router(cfg-translation-profile)# translate called 1

2. apply the voice translation-profile on the appropriate dial-peer with appropriate direction (incoming or outgoing).

Router(config)# dial-peer voice 100 pots
Router(config-dial-peer)# translation-profile incoming CHANGE_DID
