Sure thing. The main issue you were having is access to the information you want in the part of the message body where you want it. Assuming you can get that and that it's formatted in a way that the transformation functions in Kamailio can operate on it, i.e. split by delimiter versus regex extraction, you can pass around anything any way you like. :-) -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906

I think my keyboard battery is failing, it keeps dropping characters… Here’s a better example. $var(data) = $(rb{re.subst,/^rate is ([0-9]+).*$/\1/}); Regards, Hugh From: sr-users-bounces(a)lists.sip-router.org [mailto:sr-users-bounces@lists.sip-router.org] On Behalf Of Waite, Hugh Sent: 15 August 2014 10:43 To: Kamailio (SER) - Users Mailing List Subject: Re: [SR-Users] Text Operations on a Message Hi, The re.subst transformation can be used on variables to extract data. http://www.kamailio.org/wiki/cookbooks/devel/transformations#resubst_expres… $rb is the variable that contains the request body, but you can use $var or $avp variables if doing multiple operations. $var(data) = (int)$(rb{re.subst,/^rate is ([0-9+).*$/\1}); Regards, Hugh From: sr-users-bounces@lists.sip-router.org<mailto:sr-users-bounces@lists.sip-router.org> [mailto:sr-users-bounces@lists.sip-router.org] On Behalf Of AliReza Khoshgoftar Monfared Sent: 14 August 2014 20:00 To: Kamailio (SER) - Users Mailing List Subject: [SR-Users] Text Operations on a Message Hi list, How can I extract a specific part of my message body? I know that "textops" has the function "search_body(re)" but it returns True/False upon finding "re" in the body of the text, how can I return the actual text that regular expression matches? As an example, my message body is rate is 172#012 I want to extract the number "172" out of this.
