我在使 webrtc2sip 真正工作时遇到了问题。Webrtc2sip 现在在通话过程中间歇性崩溃。即使队列中只有一个呼叫处于活动状态，我也看到了这种情况。顺便说一句，我的设置涉及一台带有 Asterisk+Webrtc 的服务器。
下面给出的是崩溃期间的 webrtc2sip 控制台日志。

===============
其他详细信息：
**我使用他们的官方技术指南编译了webrtc2sip。
webrtc2sip.org/technical-guide-1.0.pdf**
第一种配置：
/configure --with-ssl --with-srtp --with-speexdsp --with-ffmpeg=no --with-ilbc=no --with-opus=no --with-vpx=no --with-amr=no --with-yuv=no --with-speexdsp=no --with-gsm=no
。我尝试安装 中指定的所有编解码器，几乎全部安装成功。有一些编解码器 libyuv、ilbc、G729 我无法安装。Webrtc2sip 首次编译成功，不包括这些编解码器。但当我拨打电话时，大多数时候都会被拒绝。而且服务经常崩溃。抱歉，我现在没有这些日志。
第二次配置
./configure --with-ssl --with-srtp --with-speexdsp --with-ffmpeg=no --with-vpx=no
这次我强制将所有视频编解码器设置为“否”。否则视频编解码器默认启用。（我认为 webrtc2sip 将它们视为是，因为它检测到它们安装在服务器中）。
服务比以前稍微稳定了一点。但是每隔 2 次呼叫就会崩溃一次。上面给出的核心转储就是由此配置生成的。我需要一些认真的帮助。
