The following expression calls t_relay() to forward a SIP message. If the forwarding fails (for example unresolvable DNS destination) then SER will send back an error message using sl_reply_error()

Hi,

My programming skills are limited but I do have some experience and am able to use SER scripts and change them with success. However I sometimes need to ask some questuions to further my trip into the SER world.

1. I'd like to know what the following expression means?

      if (!t_relay()) {
            sl_reply_error();
     };
   
   

2. What is a Realm?

Thanks
