asterisk devices and users与extensions的区别

Bydefault, FreePBX operates in "Extension Mode." In Extension Mode,devices (such as phones) and users (people) both use the same identificationnumber, i.e. their extension number. Each Device (Phone) is assigned one User(Extension) and they cannot be easily changed, without accessing the FreePBXUser Interface. A single module, entitled "extensions" will appear onthe left hand side of the FreePBX interface, and all settings relating to boththe phone and the user will appear in the same place.

FreePBXcan be switched to operate in "Device & User Mode." Device &User Mode will cause the "Extensions" module to disappear and to bereplaced with two separate modules, one entitled "Devices" (i.e.,phones) and the other entitled "Users" (i.e., Extensions).

TheDevices module sets up device related settings, i.e. the Device Number (whichshould be a number that is different from any extension number), the Device'sName (usually the location of the phone), the password the Device uses toregister with the PBX, etc. The Users module sets up the User related settings,such as the extension number, the person's name, whether that person hasvoicemail, the voicemail password, etc.

Thereare two main advantages to Device & User Mode.

First,two devices (i.e., phones) can share the same extension number. For example, ifa manager has an office on two different floors, he might want to have thephones in both offices have the same extension number, so that regardless ofwhich office he's in, a call to the same extension number will ring bothphones. Both phones can also receive intercom calls to the same extensionnumber, and both phones will show when he has a voicemail. This can beaccomplished by setting up each of his phones as a Device, setting up one User(i.e. the manager), and then assigning the User to both devices.

Second,extensions can roam from one device to another. For example, suppose that Johnand Jane both work in the same office. John works Monday, Wedneday, and Friday.Jane works on Tuesday and Thursday. When John and Jane come to work each day,they could pick up any phone that's not in use and "login" using afeature code, thereby causing their extension # to be registered to the phonethat they are in front of, so that they can start receiving and making calls.Before they leave, they can log-out using another feature code. If they bothhappen to come in on the same day for some reason, either can use any otherunassigned phone.

默认情况下,FreePBX在“扩展模式运营。“在扩展模式下,设备(如手机)和用户(人)都使用相同的识别号,即他们的分机号码。每个设备(手机)分配一个用户(扩展),他们不能轻易改变,没有访问FreePBX用户界面。单个模块,题为“扩展”将出现在左手边的FreePBX接口,和所有设置有关手机和用户都将出现在同一个地方。
FreePBX可以在“设备和用户切换操作模式。“设备和用户模式将导致“扩展”模块消失,取而代之的是两个独立的模块,一个名为“设备”(即、电话),另一个名为“用户”(即扩展)。
设备模块设置设备相关的设置,即设备号(这应该是一个数字,不同于任何分机号码),设备的名称(通常是电话的位置),密码与PBX设备使用登记,等。用户模块设置用户相关的设置,如分机号码,这个人的名字,这个人是否有语音信箱、语音信箱的密码等。
有两个主要优势设备&用户模式。
首先,两个设备(即。、手机)可以共享相同的分机号码。例如,如果一个经理有一个办公室在两个不同的地板,他可能想要的手机在办公室有相同的分机号码,所以,不管他的办公室,调用相同的分机号码将环手机。两款手机还可以接收对讲机调用相同的分机号码,和两个电话时将显示他有一个语音信箱。这可以通过设置每一个他的手机设备,设置一个用户(即经理),然后分配用户设备。
其次,扩展可以在从一个设备到另一个地方。例如,假设约翰和简在同一个办公室工作。
