用星号中的grep过滤pjsip显示频道

Question

我正在使用

asterisk -rx "pjsip show channels"

显示振铃和活动呼叫，但是由于我同时有很多分机振铃，所以我得到了类似的东西

[root@freepbx ~]# asterisk -rx "pjsip show channels"

所以...有没有一种方法可以过滤此方法，使其在每次振铃和振铃时仅显示一个条目？我尝试过

asterisk -rx "pjsip show channels" | grep -o '"[^"]\+"' | sort -t: -u -k1,1

这将显示预期的输出，但是在显示是否上升或正在振铃之前，我会松开这行，所以我尝试使用

asterisk -rx "pjsip show channels" | grep -B 1 -o '"[^"]\+"' | sort -t: -u -k1,1

但是结果是错误的非常感谢

您使用的是可读版本。只需使用机器可读的

asterisk -rx "pjsip show channels concise"

[请注意，一般来说，问询渠道不稳定。使用其他方式，例如CEL或AMI事件
