[reSIProcate] transport help



Can someone explain what is the registra port? For teststack,
 
sipstack sender;
sipstack receiver;
 
Both send and receiver has three ports: senderport, registraport and target ports
 
sender. addtransport(udp, senderport, version);
receiver.addtransport(udp, registraport, version);
 
I figured when sender's targetport pointing to the receiver's registraport, sender could send out packets to receiver.
 
But, what is the theory about these port definition? should sender also add registraport, say,
sender.addtransport(udp, registraport, version)? I don't quite get the meaning of this.
 
Anyhelp? Thanks a lot
