Description

changing dp_replace_helper() to pass a NULL value indicating no output is needed ( no need to do subst ) to dp_translate_helper()

[linuxmaniac]

is that the correct behavior for dp_match()? That is what I understand from the description

6.2.  dp_match(dpid, inval)

   The function matches the input value 'inval' using the rules with
   dialplan id 'dpid'. If the rule that was applied has attributes, they
   are stored in the variable provided via the module parameter
   'attrs_pvar'.
