[OpenSIPS-Users] Some Guidance

[Douglas Lane]

Hi Richard,

Big thanks, been playing around with the dialplan module - really rocks.

Just a question though, I'm using $fn to check the CLID, however, $fn 
has double-quotes encasing it. Is there a way that I can strip the 
double quotes from $fn (I'll copy it to an AVP first obviously) before 
passing it to dp_translate, otherwise, it doesn't match my regexes.

Thanks
Doug
