Currently, uri.* transformations only operate on perfect URIs similar to "sip:user@host;param=value". Unfortunately, most headers encapsulate the URI inside <>, which makes using the transformations on them tedious at best and involving string manipulation for the script. This patch enhances the uri.* transformations to handle URIs encapsulated with <> like "<sip:126.96.36.199;lr>" or full headers beginning with uri like "<sip:email@example.com;transport=udp>;edge=188.8.131.52" . Please apply this patch to allow script writers to more easily extract URI parts from headers or custom headers without the use of in-config string manipulation.
