[OpenSIPS-Users] regular expression matching question

[Faheem Muhammad]

Hi Machel,

Appreciate the correction; it was a typo when I posted the question.
However, as Callum mentioned earlier, the "IF" condition with the "=~"
operator doesn't fully support PCRE. It seems that any regular expression
with parentheses isn't matched using the "=~" operator.
Using "pcre_match" or an alternative regular expression would be more
suitable in this case.

Thank you
M. Faheem
