我正在尝试使用 asterisk 配置 b410p 卡。我已将电话 isdn 连接到卡的 NT 端口。这是我的配置

连接手机的端口是绿色的，所以没问题

我从 isdn 电话尝试拨打 200 测试分机并退出，出现 isdn 错误代码 3302
这是我的 extensions.conf 部分
exten => 200,1,Answer()
same => n,Playback(hello-world)
same => n,Hangup()
exten => 1000,1,Dial(dahdi/4,20)
当我尝试从控制台调用“1000”时说
Span 2: Channel 0/1 got hangup, cause 18
-- Hungup 'DAHDI/i2/-2'
== Everyone is busy/congested at this time (1:0/0/1)
-- Auto fallthrough, channel 'ALSA/default' status is 'CHANUNAVAIL'
<< Hangup on console >>
有什么建议吗？谢谢

另一个问题是：来电“工作正常”，因为电话响了（接听失败时），pri 调试未报告拨出的电话：我错过了什么？这是新的 extensions.conf
[from-dahdi]
exten => _XXXXX.,1,Dial(DAHDI/g14/${EXTEN})
exten => _XXXXX.,2,Hangup()
如何定义拨出电话的分机号？
答案1
找到解决方案 是 USB 重定向的问题（使用带有 USB-2 控制器的 pci-e 卡解决），之前我使用 USB 主机重定向（使用 libvirt），现在我重定向整个 USB 控制器，将 isdn ta 连接到 USB 端口。现在 isdn 软件电话可以拨打和接听。我忘了说 isdn ta 已连接到虚拟机。
