Dear All, 

     I installed an Asterisk on a linux PC, and X-Lite on two Windows
PCs, all in a LAN.

     But, when I make phone call from one X-Lite to another, I always get 
            
                   Call Failed: 404 not found. 


      Here is my sip.conf:
 
                  [Phone1]
                  type=friend
                  host=dynamic
                  ;defaultip=192.168.1.103
                  dtmfmode=rfc2833
                  context=SIP
                  callerid = "Me" <2124>

                  [Phone2]
                  type=friend
                  host=dynamic
                  ;defaultip=192.168.1.101
                  dtmfmode=rfc2833
                  context=SIP
                  callerid = "Mini Me" <2123>

             Following is my extensions.conf:
                  exten => 2124,1,Dial(SIP/Phone1,20,tr)
                  exten => 2123,1,Dial(SIP/Phone2,20,tr)

             Here is the Asterisk Sip debug info:
