[OpenSIPS-Users] need help on dialplan module

[Bogdan-Andrei Iancu]

Hi Ha,

The "match_exp" regexp is used only for matching the rule (against the 
input), to see if this rule is to be used - the output has nothing to do 
with this regexp.

The regexp is generated based on "subst_exp" and "repl_exp" - these two 
fields acts as a perl / sed substitution ops like "s/subst_exp/repl_exp"

Regards,
Bogdan
