That worked perfectly, thanks!

For the other beginners out there, here are two snippets for posterity:

== TO LOG ==

xlog("L_INFO", "contact.uri.host = $sel(@contact.uri.host)\n”);
xlog("L_INFO", "contact.uri.port = $sel(@contact.uri.port)\n”);


== TO COMPARE ==

#!define PORT_SERVICE_A 5062

if ( @contact.uri.port == PORT_SERVICE_A ) {
  xlog(“L_INFO", “Service A: sent $rm\n");
}



Regards,
-Michael
