Php 正在尝试为使用sipjs的网站用户之间的语音聊天设置星号。但无法配置DTLS证书。获得；主机名：未知主机“；

我正试图在Sipjs的帮助下为用户设置Asterisk Voice chat，并遵循Sipjs文档中给出的说明。用户已创建并已连接。他们可以通过Zoiper互相联系。但无法通过Sipjs或SipML5调用。当任何用户从Sipjs或SipMl5呼叫时。控制台显示以下错误：

在安装DTLS证书的过程中，我会得到“主机名：未知主机”。任何人请指导我如何正确设置星号语音聊天。

从我在您的控制台中看到的内容- 1-扩展在您的上下文中不存在 第二-在sip用户配置中设置“avpf=yes” 第三-在sip用户配置中设置“encryption=yes”

从你的书名我知道的是，你还没有为它生成证书-

mkdir /etc/asterisk/keys
cd /usr/src/asterisk-13.1.0/contrib/scripts
/ast_tls_cert -C hostname -O "Some Name" -d /etc/asterisk/keys

以下是webphone的sip配置示例：

[1000]
host=dynamic
secret=YouPassword
context=from-internal
type=friend
encryption=yes
avpf=yes
icesupport=yes
directmedia=no
disallow=all
allow=ulaw
allow=alaw
dtlsenable=yes
dtlsverify=fingerprint
dtlscertfile=/etc/asterisk/keys/asterisk.pem
dtlscafile=/etc/asterisk/keys/ca.crt
dtlssetup=actpass

如果您仍然有问题，请与我分享您的配置（希望您已经配置了webrtc支持）

有人能告诉我在配置过程中我做错了什么。您可以建议证书不能没有正确的域名。
