\nThe class implements “ManagerEventListener” to be able to be notified of asterisk events. In the constructor, by means of a “factory” we instantiate a “ManagerConnection”(line 11) that we’ll use to connect to our asterisk server.“<\/span>asterisk_server_url<\/span>“<\/span>, “<\/span>user<\/span>” and<\/span> “<\/span>password<\/span>” have obviously to be your real asterisk server url,\u00a0 manager user and password defined on asterisk.<\/span><\/span><\/span> The “run” method, called by “main” when the class gets launched, adds the class itself as a listener for the “managerConnection”(line 16), meaning that the current class will receive asterisk fired events. On line 17 we login to the “ManagerConnection”,
\nand on line 19 we enter an endless loop that just waits. Line 21 is commented out because isn’t reachable, but remember we can also logout from the connection if required.
\nMethod\u00a0 “onManagerEvent” is the one required to receive events from asterisk. We get the name of the event (line 25) to make sure it is a “Dial” event and if so we just print out the caller id. You are not guaranteed the caller id is the telephone number of the caller because of all the new available caller id services , but most of the time it is.<\/span><\/p>\n <\/p>\n
