====== Trunk ====== A trunk is a route connecting the local telephone network and other telephone network ( mainly the traditionl PSTN network or other IP PBX system). Trunks can be cataloged by the transmission media * Internet trunk (SIP，IAX) * Analog trunk (FXO口) * Digital trunk (E1 PRI) ===== Add a trunk ===== On the left menu, click [[:en:module_manual:pbx|PBX]] -> Trunk, and **[Add]** to open the trunk add page. {{:en:module_manual:pbx:trunk_add_general.jpg?768|Trunk Add For General}} ==== Requird fields ==== * **Trunk** Set the name for the trunk for identification. * **Team** Selece a team to which this trunk belongs. And after setting, this trunk can only be used in this team. If you do not assign this trunk a team, then all teams can use this trunk. * **Protocol** Choose a protocol for this trunk. * **Registry string** When you choose SIP or IAX, and in order to receive the calls from this trunk, you need to enter a registry string of the trunk sometime. Standard format:** username:password@voip.sonicwell.com:5060** * **Identity** The only identity. The system would automatically generate a string of number as the identity. And for some internet trunks, the identity needs to be the same as the trunk name, thus, manual adaption is needed here. * **Time out** When the call attempt exceeds this tim and still not gets conneted, it is considered a failure. * **Status** Whether to enable this trunk. ==== Optional fields ==== * **Templates：** Select a trunk for this trunk. The use of templates makes it easy to manage the internet trunks of the same type. * **CID Num：** The CID number displays * **CID name：** CID name displays (now only supports some trunks). * **Details：**enter the configuration parameter of the trunk * **Max calls** the max. concurrent calls allowed in the trunk ==== Advanced ==== {{:en:module_manual:pbx:trunk_add_advanced.jpg?768|Trunk Add For Advanced}} * **Enforce use rate：** When a team places outbound calls, it would match the device rate by the trunk. If you use the enforce rate, you must make it to each device to achieve outbound calls, otherwise the outbound calls would not be placed. If you do not limit the rate, you dont need to match the device rate.团队外呼时，根据中继去匹配分机费率，如果强制计费，必须匹配到分机费率才能外呼，否则不会外呼。如果不强制，那么就不需要匹配分机费率。(请修改加工一下这句谢谢) * **Always use trunk CID：**If you choose "yes" here, then no matter what number has been set outside this page, the number set in this trunk will be used. * **Cluster trunk** If you use this system and other systems together, choose **"yes"** * **Cluster trunk host** enter the cluster trunk host address. * **Black list：** number in this list cannot be placed or received. * **Black list：** If you enter numbers in this list, then only the number in this list can be placed or received. * **Detail：** for discriptive information, like its purpose etc. ===== Edit trunk ===== Double click the item to open the edit page. {{:en:module_manual:pbx:trunk_edit.jpg?768|Trunk Edit}} 点击 [编辑中继规则]，打开中继规则设置界面。 {{:en:module_manual:pbx:trunk_add_rule.jpg?768|Add Trunk Rule}} 号码进入中继后，将按你设置的规则进行匹配，如果匹配到，就按你规定的规则去移除前缀，增加前缀。 **属 性：** 包括 允许呼叫、禁用本规则、禁止呼叫。 **号码前缀：**匹配什么样的号码前缀。你写了0411 那么号码开头是0411的号码就会找到这条规则，并按规则去执行操作。 **号码长度：**要匹配的号码长度是多少。 **移除前缀：**匹配到号码后，要将你填写的前缀删除。 **增加前缀：**匹配到号码后，要将你填写的内容放到号码前边。 规则设置完成后，点击【确定】按钮进行保存。保持后的数据将显示在下方的表格中。 {{tag>:zh:模块使用说明:PBX管理 :zh:模块使用说明:PBX管理:中继 :zh:模块使用说明:PBX管理:中继:中继规则}} {{topic>:zh:中继}}
