linux - app_dial.c : dial_exec_full Unable to create channel type SIP (cause 20 Unknown)

Question

我第一次尝试在我的 Ubuntu Linux 机器上配置 Asterisk 。我安装了 Asterisk 并在执行以下命令时在我的终端中得到了这个...

root@ubuntu:~# asterisk -r

 =========================================================================
Connected to Asterisk 1.8.4.4~dfsg-2ubuntu1.1 currently running on ubuntu (pid = 1062)
ubuntu*CLI> 

现在我更新了 sip.conf 如下..

[general]
port = 5060
bindaddr = 0.0.0.0
context = others

[2000]
type=friend
context=my-phones
secret=1234
host=dynamic

[2001]
type=friend
context=my-phones
secret=1234
host=dynamic

这是我的 extensions.conf

[others]

[my-phones]
exten => 2000,1,Dial(SIP/2000)
exten => 2001,1,Dial(SIP/2001) 

现在出于测试目的，我已经下载了 Twinkle 软电话并尝试使用用户名 2000 和域 Localhost< 配置分机 2000/ 。现在我在 twinkle 上面注册后，我试图从 Twinkle 调用扩展 2001 但它在 Asterisk CLI 中给出了以下错误..

 [Apr  1 03:49:58] WARNING[2301]: app_dial.c:2041 dial_exec_full: Unable to create   channel of type 'SIP' (cause 20 - Unknown)

这是命令 sip show peers 在终端中的结果..

  Name/username              Host                                    Dyn Forcerport ACL Port     Status     
  2000/2000                  127.0.0.1                                D          5061     Unmonitored 
  2001                       (Unspecified)                            D          0        Unmonitored 
  2 sip peers [Monitored: 0 online, 0 offline Unmonitored: 1 online, 1 offline]

Sip 注册也显示为零..

ubuntu*CLI> sip show registry
Host                                    dnsmgr Username       Refresh    State                Reg.Time                 
0 SIP registrations.

这都是关于我的问题..我对 asterisk 和 Linux 都是新手，并且对这种情况感到非常震惊。请帮我解决这个问题。

Answer 1

您收到此错误是因为 2001 未在任何地方注册。

在另一个软电话上注册2001试试。
