简介

本文档介绍包含一个双区域拓扑的 VoIP 网络，该拓扑由两个 Cisco 网守管理，并且每个区域中包含一个 Cisco 网关。本文的目的是提供能够让用户避免一些已知问题的基本配置，并为基于网守的网络创建可靠基础。本文档包括所配置功能的相关技术背景信息、设计指南和基本验证与故障排除策略。

特别注意在下面的配置中，四台路由器位于同一个LAN。然而，在您的实际结构中，所有设备可以在您网络的不同部分中使用。

开始使用前 

规则

有关文档规则的详细信息，请参阅 Cisco 技术提示规则。

先决条件

本文档没有任何特定的前提条件。

使用的组件

已对该设备进行了以下配置测试：

  • 四台Cisco 2600，带Cisco IOS®软件版本12.2.8.5 ENTERPRISE PLUS/H323 MCM

本文档中的信息都是基于特定实验室环境中的设备创建的。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，请确保您在使用任何命令前已经了解其潜在影响。

配置

本部分提供有关如何配置本文档所述功能的信息。

注：要查找有关本文档中使用的命令的其他信息，请使用命令查找工具(仅注册客户)。

网关到网守配置的一般要求

在网关从关守获得正确的地址解析之前，必须满足几个条件。

要验证如下两个重要方面：

  • 所有网关都应注册到相应的网守。

  • 所有网守都应有正确的拨号计划。

注册

成功注册是第一个必需步骤。还应考虑以下附加因素：

  • 如果网关具有局外交换站 (FXS) 接口，则在普通旧式电话服务 (POTS) 拨号对等体上，添加 no register e164 命令。这可避免 Cisco Bug ID CSCdw60626（仅限注册用户）中说明的网关注册问题。 不是使用 e164 编号进行直接 FXS 的端口注册，可以为网关添加区域前缀并基于区域前缀做出路由决定。

  • 通常，首选为网关定义技术前缀。虽然技术前缀的出现主要影响呼叫路由，但是它也适于可靠的注册。

有关网关到网守注册问题的详细信息，请参阅排除网守注册问题。

呼叫路由

  • 为了实现可靠呼叫路由，应使用某种技术前缀注册所有网关。技术前缀的目的是区分不同类型的呼叫和网关的对应类型。因此，虽然可以使用技术前缀来做出路由决策，但更好的做法是使用技术前缀来根据区域前缀区分呼叫和路由类型。使用此方法，所有VoIP网关都可以配置相同的技术前缀（例如1#*，如本文档中的示例所示）。

  • 首选显式为区域前缀配置主网关。

  • 将 H.323 信令绑定到 Cisco IOS 网关或路由器上的特定 IP 地址。当Cisco IOS网关有多个被激活的IP接口时，某些H.323消息可能源自某个IP地址，而其他H.323消息则可能参考不同的源地址。如果回环接口可用于识别网关，或者网络中有一个防火墙和记帐服务器，h323-gateway voip bind srcaddr命令则是必要的。此命令已引入 Cisco IOS 软件版本 12.1.2T，为虚拟接口配置 H.323 支持中进行了相应介绍。

有关网守呼叫路由的详细信息，请参阅了解 Cisco IOS H.323 网守呼叫路由。

本文档使用以下配置。

网守和网关的配置的验证对于排除网关到网守的问题故障非常重要。为了简化对配置的了解，已删除所有无关配置命令。

验证

本部分提供的信息可帮助您确认您的配置是否可正常运行。

命令输出解释程序工具（仅限注册用户）支持某些 show 命令，使用此工具可以查看对 show 命令输出的分析。

注意：在尝试任何debug命令之前，请参阅有关debug命令的重要信息。有关下面的命令的详细信息，请参阅本文档的故障排除命令部分。

故障排除

本部分提供的信息可用于对配置进行故障排除。

故障排除命令

要排除故障，请检查以下几个重要方面：

  • 所有网关都已注册到相应网守。

  • 网关应具有正确的拨号计划（配置了拨号对等体）。

  • 网守应具有正确的拨号计划（配置了区域前缀）。

故障排除和调试 VoIP 呼叫基础中描述的操作步骤，补充了网关与网守交互作用相关的调试和显示命令的输出，应当被用作解决与其他Cisco IOS子系统相关的语音问题。show命令的示例输出突出显示了以上步骤，而debug输出则显示了您的所有4台路由器上的RAS和H225消息的顺序。

注意：debug h225 asn1命令会生成非常大的输出，因此应该谨慎使用。某些不必要的输出已从下面的 debug 命令中删除。

注意：在发出debug命令之前，请参阅有关debug命令的重要信息。
