[OpenSIPS-Users] Problem using xlog with variables

[Bogdan-Andrei Iancu]

Hi Jan,

You can print via variables strings containing again references to other 
variables - there is only one level of variable evaluation.

You should do it:
     $var(msg) = $rm + "received on " + $var(hostname);
     xlog("L_INFO", "$var(msg)");
