Ip 电话配置 标题这么写，有点不太符合。具体的情况应该是这样的，有一台 3825 路由器，内插有PVDM2-64 模块和 VIC2-4FXO 模块。路由器连接一台可端口供电的 Cisco3560 交换机， IP 电话连在交换机上。 电话网络结构希望是这样的： PBX Model The simplest model is the PBX model, in which most of the IP phones in your system have a single unique extension number. Incoming PSTN calls are routed to a receptionist at an attendant console or to an automated attendant. Phone users may be in separate offices or be geographically separated and therefore often use the telephone to contact each other. For this model, we recommend that you configure directory numbers as dual-lines so that each button that appears on an IP phone can handle two concurrent calls. The phone user toggles between calls using the blue navigation button on the phone. Dual-line directory numbers enable your configuration to support call waiting, call transfer with consultation, and three-party conferencing (G.711 only). Figure 3 shows a PSTN call that is received at the Cisco Unified CME router, which sends it to the designated receptionist or automated attendant (1), which then routes it to the requested extension (2). 图 1 Incoming Call Using PBX Model 图 1 Incoming Call Using PBX Model How to Configure Phones for a PBX System 下面先了解一下基本概念，然后在看如何在 Cisco3825 上配置SCCP 电话。 配置电话可以进行基本呼叫的信息(Information About Configuring Phones to Make Basic Calls) (一)CME 里的电话概念(Phones in Cisco Unified CME) ephone 的概念是相对于 SCCP 来说的，而 voice-register pool 则是相对于 SIP。这两种名词都是 Cisco Unified CME 里电话的配置名称。无论是 IP 电话还是模拟电话都需要配置一个唯一的标记符(tag)。 (二)姓名地址录号码(Directory Numbers) 一个姓名地址录号码，对于SCCP 可以被视为ephon...
