Hi all
I need to extract a part of the INVITE msg:
INVITE sip:+41796159999@82.197.185.185;user=CSC10824 SIP/2.0
I need
10824
in a avp variable.
Hi Oli,
The string you are operating on is called the Request URI, which is exposed by the $ru pseudovariable. The best way to extract it is to use the transformations[1] specifically for extracting URI parameters, which is what 'phone' is:
$avp(user_id) = $(ru{uri.param,user});
If you want '10824' rather than CSC, you can extract a substring:
$avp(user_id) = $(ru{uri.param,user}{s.substr,3,0});
