2、个逻辑分区。先决条件要求Cisco 建议您了解以下主题：Cisco IOSa71Cisco Unified CMEa71使用的组件本文档中的信息基于以下软件和硬件版本：Cisco IOS版本15.0(1)XA或以上a71Cisco Unified CME版本8.0或以上a71本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。 背景信息Cisco Unified CME支持限制一高层次类并且允许您对逻辑上分成其资源例如PSTN中继、IP中继、IP电话和模拟电话，到不同的组。您创建各自的
3、资源组的一个LPCOR策略矩阵并且定义了其LPCOR策略对接受或拒绝起源于任何其他资源组的呼叫。您能定义每资源组的一项LPCOR策略。默认LPCOR策略意味着没有在呼叫来源和其目标目的地之间的限制。您创建定义了呼叫限制适用于呼叫产生或终止在资源的这些类型的LPCOR策略：模拟电话-，如果电话本地注册对Cisco Unified CME， TRAI法规允许一个模拟局外交换站(FXS)电话接受PSTN和VoIP呼叫。本地连接的电话不必须关联与任何资源组;默认LPCOR策略应用对此电话类型。a71IP电话- LPCOR支持内部呼叫控制协议(SCCP)和会话初始化协议(SIP) IP电话。如果IP电话
4、注册本地对Cisco Unified CME通过LAN， TRAI法规允许IP电话接受PSTN和VoIP呼叫。如果IP电话注册对Cisco Unified CME通过广域网，必须从远程IP电话阻塞PSTN呼叫。a71如果IP电话总是注册对从同一个本地或远程区域的Cisco Unified CME，电话配置有静态LPCOR策略。 如果电话是莫比尔类型IP电话并且移动在本地和远程地区之间，例如Extension Mobility电话或softphone (CIPC)， LPCOR策略动态地设置当前根据IP电话的注册的IP地址。PSTN建立中继-流入LPCOR资源组用PSTN中继关联通过语音端口或中
5、继组。流出的LPCOR资源组在呼出POT dial-peer应用，并且这可以根据语音端口或中继组也。VoIP中继-一个流入VoIP长途电话(H.323或SIP)关联与根据远程IP地址的LPCOR策略如下：流入H.323长途电话-上一个集线器或始发网关的IP地址a71流入SIP长途电话- (a)始发网关的IP地址， (b)从最早期的主机名通过报头流入邀请消息a71如果主机名在域名格式， DNS查询执行为了解析名称在IP地址。 VoIP目标的LPCOR策略通过出局的VoIP拨号对等体的配置确定。配置网络图注意：使用命令查找工具（仅限注册用户）可获取有关本部分所使用命令的详细信息。参见与两个需求的此
