急问 ! 透过pri打手机 当电信提供语音答覆时就断线

问下
目前系统 freeiris2-2.4 + D410P (openvox)
在freeiris底下分机 透过 pri 外拨手机 , 手机没接 电信转语音回答 ,
此时 freeiris就挂断这通电话
尝试在 /etc/asterisk/chan_dahdi.conf 的 for digital 加入一段 callprogress=yes
但是 还是一样会断话
估计 这个问题是 电信要转到语音回答时 会送一个信号回来 因此 freeiris会误认 而切断这个电话
请问是否有人可以 提供方法解决问题
谢谢

把外拨手机时候的PRI信令转储下来分析一下。看看跟正常的呼叫有什么不同。

这是执行 pri debug span 的 log

hi:
你检查这些问题：
1） dial) Options: (DAHDI/R0/0916840931|60|tTkK) 这个通道是确认没有问题的吗？
2） 你的PRI 是up. active 的还是down 的。
3） 你的线路只是打手机号码有问题吗？ 如果是，你换其他运营商的手机试试。
4） callprogress=yes 这个设置根本和数字卡无关！
5） 设置pridialplan= local (or unknown, private, national, and international)

Hi 很高興收到您的回復
1） dial) Options: (DAHDI/R0/0916840931|60|tTkK) 这个通道是确认没有问题的吗？
這是 freeiris2的參數 60代表外撥響鈴時間 tTkK是asterisk的撥號參數
这是freeiris2的参数 60代表外拨响铃限制时间/秒（超过此时间自动断线） tTkK是asterisk的拨号参数
2） 你的PRI 是up. active 的还是down 的。
PRI 是up , active
PRI 是up , active
3） 你的线路只是打手机号码有问题吗？ 如果是，你换其他运营商的手机试试。
只有打手機有問題 而且換了其他家手機 只是掛機時間長短不同
只有打手机有问题 而且换了其他手机运营商 只是挂机时间长短不同而已
4） callprogress=yes 这个设置根本和数字卡无关！
谢谢
5） 设置pridialplan= local (or unknown, private, national, and international)
pridialplan= unknown



-- DAHDI/62-1 is ringing
-- DAHDI/62-1 is busy
从ringing到busy依照不同的手机运营商 时间也不同 间隔搭约15~30秒
我假设 是否运营商pri有发出什么讯息 而让我们的系统当成busy而送出disconnect的需求
是否有什么命令 可以撷取pri之间互送讯息 例如cause xx的编码 这样有助于厘清 到底是哪里的问题

谢谢您的协助

1） DAHDI/R0/ 确认没有问题
2） DAHDI/62 通道的状态是什么？
