Review Questions
Define digit manipulation.
Of the digit manipulation techniques digit stripping, digit forwarding, digit prefixing, number expansion, and CLID, which are executed after the outbound dial peer is matched but before the numbers are transmitted?
By default, POTS dial peers strip any outbound digits that explicitly match their destination pattern. What are two simple ways to prevent the router from stripping all the digits?
When is a number expansion executed, and how can you test its action?
Given the following voice translation rule, how would a dialed string of 913012345678 be translated?
/^\(91\)301\(.......\)/ /1\2/
