c - 如何在icedemo中设置stunserver和turnserver？

Question

我正在使用 pjsip 项目 2.3。我想使用 Ice 来 imp 我的 p2p。

所以我编译了icedemo.c，命令行是“-s stunserver.org”。

但是当我运行演示时，我发现它不能很好地工作。 转储信息如下:

Answer 1

我的基于 PjSIP 的应用程序也遇到了类似的问题。 stunserver.org 上的 STUN 服务器似乎出现问题。它会时不时地下降。

尝试使用 google 提供的 STUN 服务器之一。我发现它们非常可靠。

stun.l.google.com:19302
stun1.l.google.com:19302
stun2.l.google.com:19302
stun3.l.google.com:19302
stun4.l.google.com:19302
