Question

您好我使用Python Asterisk来处理我的星号服务器。我已经能够使用以下代码收听当前的呼叫。

     def handle_event(event, manager):
     with ctx:

        if event.name == 'CoreShowChannel':
            user_id = event.message['AccountCode']
            user_id = int(user_id)
            data = {
            "channel":event.message['Channel'],
            "channel_state":event.message['ChannelStateDesc'],
            "duration":event.message['Duration'],
            'extension': event.message['Exten'],
            'line': event.message['ConnectedLineNum'],
            'user_id': user_id,
            'context': event.message['Context'],
            'caller_id': event.message['CallerIDNum']
            }

            system = System()
            user = system.getUserById(user_id)
            if user:
                profile = {"first_name":user.first_name,    "last_name":user.last_name}

            data.update(profile)
            g.channels.append(data)
        if event.name == 'CoreShowChannelsComplete':
            g.complete = True
    @app.route('/live-calls')
    def live_calls():
        g.complete = False
        g.channels = []
        manager = asterisk.manager.Manager()
        manager.connect(hostname)
        manager.login(username, secret)
        manager.register_event('*', handle_event)
        res = manager.send_action({'Action':'CoreShowChannels'})

        while not g.complete:

            time.sleep(0.1)
            manager.close()
            if len(g.channels) < 1:
                return json.dumps({"response":g.complete})
            return json.dumps(g.channels)

此代码用于其目的并按预期工作，现在如何实现挂起方法，当我单击挂断按钮时，当前调用挂起。问题是我知道有一个Hangup事件，但我甚至不知道要检查的对象或变量或者在哪里听。

Answer 1

我刚刚调用了将通道名称作为参数的hangup方法。

我不知道有什么方法

manager.hangup（信道）

您必须向AMI发送命令。您可以在Asterisk CLI中列出命令及其参数

pbx*CLI> manager show commands
  Action                          Synopsis
  ------                          --------
  AbsoluteTimeout                 Set absolute timeout.
  AGI                             Add an AGI command to execute by Async AGI.
  AOCMessage                      Generate an Advice of Charge message on a chan
  Atxfer                          Attended transfer.
  BlindTransfer                   Blind transfer channel(s) to the given destina
  Bridge                          Bridge two channels already in the PBX.
  BridgeDestroy                   Destroy a bridge.
  BridgeInfo                      Get information about a bridge.
  BridgeKick                      Kick a channel from a bridge.
  BridgeList                      Get a list of bridges in the system.
  BridgeTechnologyList            List available bridging technologies and their
  BridgeTechnologySuspend         Suspend a bridging technology.
  BridgeTechnologyUnsuspend       Unsuspend a bridging technology.
