  Hi, I receive INVITE like this:

  INVITE sip:client_xxx2004@domain.org SIP/2.0

 and I get from an $avp(CLIENT) the value "client_xxx".

 I need to strip from $rU the lenght of $avp(CLIENT), this is:

  # Original $rU => client_xxx2004
  strip($avp(CLIENT));
  # New $rU      => 2004

 Unfortunatelly "strip()" doesn't accept a PV as parameter, but a static
integer. 
Great, s.substr does allow pv as parameters:

   $(var(x){s.substr,$var(num),0})
