Re: [SR-Users] Find Values in User part of Diversion URI

Hello, for the first question, you could use textops https://www.kamailio.org/docs/modules/devel/modules/textops.html#textops.f.… or just cfg regular expression match on the PV together with a transformation if ($(hdr(Diversion){uri.user}) ~= "...") to see if the header field contains the value. For the second question, there is not function right now that is the opposite of the is.numeric. You could use some regular expression replace transformation for example to achieve a similar result, I think.

In Kamailio Native 5.5.2 I want to be able to look into this field $(di{uri.user}) and "find" or see if it "contains" a value i.e Diversion: "TEST" sip:112233445566@xxx.xxx.xxx.xxx;user=phone; find 234 or contains 234 I know how to do this in in KEMI Python but for the life of me cant get my head around it in Native. 2ndly is there an opposite to {s.numeric} Removes all non-numeric parts of string. I want the ability to strip all numeric parts. Keep us the good work. Lewis
