我正在尝试在星号和 Skype 连接之间进行通信。我有一个使用 1 个频道注册的 sip 个人资料。此外，星号注册到 sip.skype.com 好。从 CLI：
sip 显示同行
skype/99051000XXXXXX 63.209.144.201 Yes Yes 5060 OK (178 ms)
sip 显示注册表
Reg.Time
sip.skype.com:5060 N 99051000XXXX 30 Registered
Tue, 08 Apr 2014 22:18:29
1 SIP registrations.
但是，每当我尝试拨打 Skype 电话时，我都会收到：
*CLI> == Using SIP RTP CoS mark 5
-- Executing [4321@LocalSets:1] Dial("SIP/ZOI6001-00000038", "SIP/skype/4321") in new
stack
== Using SIP RTP CoS mark 5
-- Called SIP/skype/4321
== Everyone is busy/congested at this time (1:0/0/1)
-- Auto fallthrough, channel 'SIP/ZOI6001-00000038' status is 'CHANUNAVAIL'
出于某种原因，我想我应该提一下，每当我重新加载 sip 时，它会说
`Using Cos mark 4`
而不是像上面那样的 Cos mark 5。
在 sip.conf 中：

我的拨号方案：
[from-trunk]
exten => 1234,n,Dial(SIP/XLX6003,15);
[from-local]
exten => 4321,1,Dial(SIP/skype/${EXTEN})
sip debug (sip set debug on) 显示：
