[SR-Users] Kamailio Transformation Assignment to an AVP

[Daniel-Constantin Mierla]

Hello,

I tested with:

     xlog("===============================+++: [$rb]\n");
     $var(b) = $rb;
     $var(c) = $(rb{re.subst,|.*m=audio [0-9]+ RTP/AVP ([0-9 ]+).+|\1|s});
     # $var(c) = $(var(b){re.subst,|.*m=audio [0-9]+ RTP/AVP ([0-9 
]+).+|\1|s});
     xlog("===============================+++: [$rb]\n");
     xlog("==================================: [$var(c)]\n");

and everything looked fine. Could be something specific for your config 
or environment, what is content-length of your invite?

Cheers,
Daniel
