Well, you have to learn how Asterisk matches incoming calls for peers.  
The peer matching is done on ip/port and will match the first one in  
the internal list, which is the last one in the configuration. All  
incoming calls will come to e911-dp2 in your configuration, since both  
peers has the same ip address and port.
