[OpenSIPS-Users] How to get the name-addr within a From header?

[Răzvan Crainea]

Hi, Gordon!

name-addr is basically the entire header, and you can access it using 
$hdr(From).
However, it looks like you are looking to get the From header username, 
that, as Grant pointed out, is returned by the $fU variable. Does this 
solve your problem?
