呼叫语音信箱时，星号中没有声音

Question

我刚开始玩星号。目前安装在 CentOS 7 上，Asterisk 版本为 13。

这是我直接从 Zoiper 呼叫语音信箱时得到的结果

-- Executing [8500@demo:2] VoiceMailMain("SIP/2001-00000028", "@demo") in new stack
-- <SIP/2001-00000028> Playing 'vm-login.gsm' (language 'en')
-- <SIP/2001-00000028> Playing 'vm-password.gsm' (language 'en')
-- Incorrect password '' for user '2001' (context = demo)
-- <SIP/2001-00000028> Playing 'vm-incorrect-mailbox.gsm' (language 'en')
   ....

这就是我在 extension.conf 中的内容

exten => 8500,1,Answer
exten => 8500,2,VoiceMailMain()
exten => 8500,3,Hangup()

这是在voicemail.conf中

[demo]

2001 => Demo Test, demo@127.0.0.1

这是 sip.conf 中的用户

[general]

port = 5060
bindaddr = xxx.xxx.xxx.xxx
allow=all           
context = bogon-calls ; Send SIP callers that we don't know about here

[2001]

type=friend           ; This device takes and makes calls
username=demo_test         ; Username on device
secret=1234 ; Password for device
host=dynamic          ; This host is not on the same IP addr every time
context=demo      ; Inbound calls from this host go here
mailbox=100   

/var/lib/asterisk/sounds/en 中的所有 .gsm 文件..
