A Chairde, I am looking to test my Asterisk server with PROTOS, but having some problems. I am trying commands.The PROTOS tool definitively works, I think I am putting wrong TOURI in ( user@asterisk-server ) , 123456 is number of softphone hanging off switch, not the Asterisk server. Would appreciate some help , and other test advice.
