【问题描述】：

我正在使用

asterisk -rx "pjsip show channels"

显示正在响铃的通话，但由于我有很多分机同时响铃，所以我得到了类似的东西

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

  Channel:  <ChannelId........................................>  <State.....>  <Time.....>

Objects found: 24

所以……有没有一种方法可以过滤这个，每次来电响起时只显示一个条目？我试过了

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

这将显示预期的输出，但我会在显示是否启动或是否响铃之前松开线路，所以我尝试了

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

但结果是错误的非常感谢

标签： grep asterisk freepbx

【解决方案1】：

您正在使用人类可读的版本。只需使用机器可读的

asterisk -rx "pjsip show channels concise"

请注意，一般询问渠道是不稳定的。使用其他方式，例如 CEL 或 AMI 事件

【讨论】：

谢谢，您能给我指出如何通过 AMI 事件完成此任务的方向吗？
只听 NewChannel、Bridge 和 Hangup 事件。参见 FOP 面板开源代码。
