我正在使用 Starpy 和 Twisted 为 Asterisk IVR 实现开发一个 FastAgi 应用程序。到目前为止，该应用程序在只有一个电话呼叫时运行良好。

在建立第二个呼叫后，来自 Asterisk 的所有连续响应都将发送到第二个呼叫：属于第一个呼叫的流音频在第二个呼叫中听到，Hangup() 断开第二个呼叫（第​​一个保持连接直到手动断开与软电话的连接）

我正在使用带有 Elastix 发行版的 X-lite 软件电话。我的 FastAgi 服务器在 Windows 笔记本电脑上。在 Extensions_custom.conf 我有这些条目来路由呼叫：

扩展 => 2000,1,AGI(agi://10.0.0.7:4573) 扩展 => 2000,n,Hangup()

这是在服务器上设置协议的方式：

logging.basicConfig()
fastagi.log.setLevel( logging.DEBUG )
f = fastagi.FastAGIFactory(MyIVRApplication())
reactor.listenTCP(4573, f, 50, '10.0.0.167') 
reactor.run()

我使用 starpy 提供的示例之一构建了我的应用程序，即 DialPlan() 应用程序，它只播放应用程序被访问的次数。即使那个应用程序在运行而不是我的应用程序时也有同样的问题，只能正确处理一个调用。

我使用的是无线网络，但使用电缆时也会发生同样的情况。我尝试了带有星号的虚拟机（在 virtualbox 中）和物理机。一样。在 Android 手机上安装了不同的软件电话。一样。使用物理IP电话。一样。我唯一还没有尝试过的是将我的 FastAgi 服务器移动到 linux 机器上，而不是使用我的 windows 笔记本电脑。

任何帮助将不胜感激。

提前致谢。

我正在从 Asterisk 添加 AGI 调试日志。如您所见，在第二个呼叫建立后，所有的 Tx 和 Rx 命令都从第二个通道发送/接收。Asterisk 不再与保持连接的第一个通道对话。

感谢您提供完整信息：

现在，您所拥有的设置的明显缺陷如下： Dialplan() 在最初传递给 FastAGIFactory 时被启动。从那里开始 - 你总是一遍又一遍地访问同一个类的实例。现在 - 每当有新调用进入时，都会调用Dialplan().__call__()方法并且Dialplan().agi参数会被最后一次调用覆盖。查看您使用的示例，我建议尝试以下方法，然后从那里获取：

#! /usr/bin/env python
"""Read digits from the user in various ways..."""
from twisted.internet import reactor, defer
from starpy import fastagi, error
import logging, time

log = logging.getLogger( 'hellofastagi' )




class DialPlan( object ):
    """Stupid little application to report how many times it's been accessed"""
    def __init__( self,application, agi ):
        self.application = application
        self.agi = agi
    def start( self ):
        """Begin the dial-plan-like operations"""
        return self.agi.answer().addCallbacks( self.onAnswered, self.answerFailure )
    def answerFailure( self, reason ):
        """Deal with a failure to answer"""
        log.warn( 
            """Unable to answer channel %r: %s""", 
            self.agi.variables['agi_channel'], reason.getTraceback(),
        )
        self.agi.finish()
    def onAnswered( self, resultLine ):
        """We've managed to answer the channel, yay!"""
        return self.agi.wait( 2.0 ).addCallback( self.onWaited )
    def onWaited( self, result ):
        """We've finished waiting, tell the user the number"""
        return self.agi.sayNumber( self.application.count, '*' ).addErrback(
            self.onNumberFailed,
        ).addCallbacks(
            self.onFinished, self.onFinished,
        )
    def onFinished( self, resultLine ):
        """We said the number correctly, hang up on the user"""
        return self.agi.finish()
    def onNumberFailed( self, reason ):
        """We were unable to read the number to the user"""
        log.warn( 
            """Unable to read number to user on channel %r: %s""",
            self.agi.variables['agi_channel'], reason.getTraceback(),
        )

    def onHangupFailure( self, reason ):
        """Failed trying to hang up"""
        log.warn( 
            """Unable to hang up channel %r: %s""", 
            self.agi.variables['agi_channel'], reason.getTraceback(),
        )


class CallCounterApplication(object):
    def __init__( self ):
        self.count = 0

    def __call__(self,agi):
        self.count = self.count+1
        dp = Dialplan(self,agi)
        return dp.start()


if __name__ == "__main__":
    logging.basicConfig()
    fastagi.log.setLevel( logging.DEBUG )
    f = fastagi.FastAGIFactory(CallCounterApplication())
    reactor.listenTCP(4573, f, 50, '10.0.0.167') # only binding on local interface
    reactor.run()

我在这里所做的是创建一个应用程序容器，它将在每次成功调用时创建一个新的 Dialplan() 实例。

编辑：请注意 - 因为我没有可用的星号框，所以没有经过测试，并且在 1:1 复制粘贴时可能无法运行。但是原理还是一样的
