Asterisk Asterisk Support

Hi Everyone,

I am trying to do stress testing via SIPp

this is my sip.conf
[asterisk02]
type=friend
context=testing
host=10.168.1.107(my test server)
user=sipp
canreinvite=no
allow=all

this is my extensions.ael
context testing {
1 => {
Answer();
//Background(6604);
//Wait(2);
//&queue_helpdesk(0);
Hangup();
};
};

I am getting following error in asterisk console
