Voice translation vs num-exp cpu efficiency

[mahdihabashi]

so guys I have a scenario that when incoming calls come from PSTN to my Gateway they must be manipulated.

1) 41585290 ----> 860

2) 41585000 ----> 290

3) 41585... ------> ...

as u know i can do these digit manipulations with voice translation rules and with num-exp but i wanna know which one is better and more efficient as router resource aspect.

Voice translation rules:

voice translation-rule 3

 rule 1 /^41585290$/ /860/

 rule 2 /^41585000$/ /290/

 rule 3 /^41585\(...$\) /\1/

num-exp :

num-exp: 41585290 860

num-exp: 41585000 290

num-exp : 41585... ...

Num-exp is a old, outdated functionality. You’re better of to use voice translation rules.
