you have to use perl like regular expression, something like
"/(\+)(.+)/\2/" -- I am not a perl master, if does not work, pleas check
perl manual, you should find a lot online.

Will take more to manipulate that variable, because it is a reference
into a buffer -- changing directly there will require to
shift/alloc/free some memory and will break other pseudo-variables which
must be re-referenced again, which costs a lot of time. Anyhow, this is
not possible now in OpenSER and I do not think it will change soon, if
ever, since will introduce big performance and architectural penalty to
server's design.
