小弟初次来此，请多关照！

我装了TrixBox. 现在有一个问题，就是如何限制某些分机，让他们只能打本地电话，不能拨打长途。请各位前辈指教！谢谢！

欢迎小兵！

限制内线分机拨打长途，最简单的方法是在out bound route上设置密码。

如果你不想用密码，而是针对分机，那就要做一些手工的修改了，其实也不是很麻烦。

这个例子也许对你有帮助。

先来看一下系统环境：我有一个设置好的TrixBox，内线分机111（SIP 电话），112（IAX 软电话），113，....等等。有两个SIP outbound route, 一个是用来拨打本地电话。另一个用来拨打长途，用来拨打长途。当所有的基本设置通过FreePBX完成后，所有的分机均可以任意拨出本地电话或长途电话。

目的：限制分机111和112，使它们只能拨打本地电话，不能拨打长途电话。其他的分机不做任何限制。

好了，让我们看一下此时分机的设置：打开任意一个分机的设置，无论是SIP或IAX，我们可以看到，其context 全是 from-internal，也就是说，当用户拨打电话时，要服从[from-internal]的规定。

现在我要建立一个新的[from-restricted]，在里面不设置长途的route。然后，把111和112的context 改成 [from-restricted] ，这样，111和112就不能拨打长途电话了。

下面，我就用TrixBox的Config Edit来创建这个新的context。

打开两个浏览器窗口（或者两个Tab）,在Config Edit下打开extensions_additional.conf 文件，在左面点击outbound-allroutes，就会看到：

请教下版主，我按照您给出的方法获得了成功，但是我升级到Trixbox2.5现在同样的配置，不过用户什么电话都不能打了，想请教下为什么。附上配置：
[from-internal-custom]

include => from-internal-trixbox

;1234,1,Playback(demo-congrats) ; extensions can dial 1234
;1234,2,Hangup()
;h,1,Hangup()
;include => custom-recordme ; extensions can also dial 5678

; custom-count2four,s,1 can be used as a custom target for
; a Digital Receptionist menu or a Call Group
;[custom-count2four]
;s,1,SayDigits(1234)
;s,2,Hangup

; custom-recordme,5678,1 can be used as a custom target for
; a Digital Receptionist menu or a Call Group
;[custom-recordme]
;exten => 5678,1,Wait(2)
;exten => 5678,2,Record(/tmp/asterisk-recording:gsm)
;exten => 5678,3,Wait(2)
;exten => 5678,4,Playback(/tmp/asterisk-recording)
;exten => 5678,5,Wait(2)
;exten => 5678,6,Hangup

[from-restricted]
