Asterisk IAX trunk

Hi All

     I am trying to connect two asterisk servers using Voip trunk ( IAX) , i am using Asterisk GUI 2.0 . 

Server 1

IP addrress = 192.168.5.117
Local number = 6000 - 6800
COntext = DLPN_DialPlan1
extension used for trunk = 6050

server 2

ip address = 192.168.5.118
local number = 7000 - 7900
COntext = DLPN_DialPlan1
extension used for trunk = 7050

On both the servers i can see that the servers are registered . however when i make a call this is what i get .
