当我尝试从CSipSimple连接到Asterisk服务器时，通过Cisco 路由器 ，在同一个networking上，Asterisk日志显示尝试的连接：

由于Jitsi显示类似的错误 ，它似乎不是客户特定的。 因为Mac上的Jitsi和Android手机上的CSipSimple都可以拨打语音电话，所以在我看来，正确地消除路由器上的防火墙是一个原因。
与此同时，我已经禁用了服务器上的防火墙来消除这个潜在的问题，这当然可能是没有必要的。
当星号回答401 Unauthorized我怎么知道为什么连接未经授权？
完整的日志太大，不能发布在这里。 虽然sip set debug on没有提供任何输出，该命令的输出在这里 ，虽然这是与Jitsi。
401未授权不是一个错误：身份validation机制如何在SIP上工作（请参阅此答案）
该行：
[Mar 23 20:02:10] NOTICE[4067] chan_sip.c: Registration from '<sip:[email protected]>' failed for '192.168.0.15:39462' - Wrong password
看起来很清楚：你的SIP客户端的密码是错误的，authentication不成功。 sip.conf中的SIP密码通过对等定义（201）中的“secret”参数。
