python - Asterisk 测试套件 : phone not ringing

Question

我的extensions.conf为:

[users]
exten=>111,1,Dial(SIP/demo-alice,5)
exten=>111,n,UserEvent(TestResult,result:pass)
exten=>222,1,Dial(SIP/demo-bob,5)

可以了，电话可以互相拨号。在Python测试中:

df = ami.originate(
 channel = "Local/222@users",
 exten = "111",
 priority = "1",
 context = "users")

启动测试时，它失败并给我一个警告:

Unhandled error in Deferred:
Unhandled Error
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/starpy/manager.py", line 153, in lineReceived
    self.dispatchIncoming()  # does dispatch and clears cache
  File "/usr/lib/python2.7/dist-packages/starpy/manager.py", line 241, in dispatchIncoming
    callback(message)

    self._startRunCallbacks(result)

    current.result = callback(current.result, *args, **kw)

    raise error.AMICommandFailure(message)
starpy.error.AMICommandFailure: {'message': 'Originate failed', 'response': 'Error', 'actionid': 'VirtATS3-36015280-2'}

通过 CLI 发起的工作正常:

channel originate Local/222@users extension 111@users

222响铃，接听电话后111开始响铃。

更新

弄清楚如何在 ami.originate() 中发送 SIP header 。找到here 。坏事是它不起作用 - 发起失败，就像上面记录的错误一样。在 dialplan 中发送 header 也不是解决方案。有什么帮助吗？

    df = ami.originate(
        channel = "Local/222@users",
        exten = "111",
        priority = "1",
        context = "users",
        variable = {
            "SIPAddHeader":"Call-Info: answer-after=0"
            })

Answer 1

除非 channel 双方都得到应答，否则发起 AMI 操作将失败。您在这里有几个选择。您可以确保每个人都有答案，或者您可以处理原始失败(尽管您可能应该这样做以避免传播扭曲的异常):

def __handle_originate_failure(self, reason):
    print "Originate failure: %s" % reason
    return reason  

df = ami.originate(
    channel = "Local/222@users",
    exten = "111",
    priority = "1",
    context = "users")
df.addErrback(__handle_originate_failure)

请注意，TestCase 类为 Originate 失败提供了一个默认处理程序 (handleOriginateFailure)，该处理程序将自动失败并停止测试。如果您希望您的 Originate 始终成功，您可能需要使用它。
