我正在尝试在由pjsip管理的2个星号扩展名之间进行电话会议。 我想打电话给123和124，然后让他们通话。
我已经设置了两个不同的传输方式和两个帐户，这不是强制性的，但这是我正在尝试的方式。无论如何，将一个帐户用于两个通话都很好。
问题是以下代码：

self.sem.acquire()

self.sem.release()

print '%s playback is done' % pid

# print "Hello world, I can talk!"
if self.call.info().state == pjsua.CallState.DISCONNECTED:
current_call = None
print 'Current call is', current_call

产生以下结果：

第二个呼叫没有开始。事实并非如此，我认为conf_slot仍为-1，因此不可能桥接：
i.conf_connect(conf_slot, conf_slot_2)
i.conf_connect(conf_slot_2, conf_slot)
任何提示将不胜感激。
答案 0 :(得分：1)
您的第二通电话似乎没有建立。您混合了很多代码。我建议您尝试使用外部SIP客户端（例如，同理心（https://en.wikipedia.org/wiki/Empathy_(software) + SIP插件））首先使呼叫正常工作
在进行工作以通过会议网桥接听来电时，请尝试使用2个线程来管理2个不同的端点。如果pjsip回调很忙（直到长时间任务结束才使用），其他回调将不会触发，因此无法使其正常工作。
尝试隔离创建自定义类和来自不同线程的呼叫的呼叫/帐户代码。
