Setting up echo test

how could I setup an echo test on asterisk?


Shouldn’t this be one of the default dial-plan contexts found on extensions.conf file. Anyway, here is what mine looks like from extensions.conf file:

exten=>500,1,Noop(UnixTime) exten=>500,n,SayUnixTime(,EST5EDT) exten=>500,n,NoOp(demo-echotest) exten=>500,n,Playback(demo-echotest) exten=>500,n(echo),Echo() exten=>500,n,Playback(demo-echodone) exten=>500,n,Hangup()
It uses extension 500 and goes to announce a local date/time before annoucing the echo test.
