使用PjSIP的VoIP:pjsua_acc.c SIP注册失败，状态= 408(请求超时) [英] VoIP using PjSIP : pjsua_acc.c SIP registration failed, status=408 (Request Timeout)

问题描述

我正在尝试运行 http://中给出的测试VoIP程序www.pjsip.org/pjsip/docs/html/page_pjsip_sample_simple_pjsuaua_c.htm

我正在尝试在 http://www1.cs.columbia上存在的公共SIP服务器.edu/sip/servers.html

但是我总是收到错误消息，

But I always get error message as

14:33:25.515 pjsua_acc.c SIP注册失败，状态为408(请求超时)

14:33:25.515 pjsua_acc.c SIP registration failed, status=408 (Request Timeout)

我以前从未使用过SIP，我无法猜测问题出在哪里.有没有简单的方法可以测试SIP服务器?有人知道可以使用的公共免费SIP服务器吗?

I never used SIP before, I am not able to guess where the problem is. Is there any simple way to test SIP servers? Does anybody know public free SIP server that works?

谢谢

推荐答案

408超时消息通常表示用户代理(在本例中为您的pjsip应用程序)发送了请求，但未得到响应.

The 408 timeout message typically means that the user agent, in this case your pjsip application, sent it's request but did not get a response.

我参与了一项免费的SIP服务，名为 sipsorcery ，您可以使用该服务来测试软件.它使您可以使用Silverlight浏览器应用程序或telnet控制台查看SIP消息的完整轨迹，这在尝试进行故障排除时非常方便.

I'm involved in a free SIP service called sipsorcery that you can test your software with. It lets you view a full trace of your SIP messages with either a Silverlight browser application or telnet console which is extremely handy when trying to troubleshoot.
