關於此翻譯

思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

簡介

本文研究具有雙區域拓撲的VoIP網路，該拓撲由兩個Cisco網守管理，每個區域各有一個思科網關。本文的目的是提供一個基本配置，允許使用者避免一些已知問題，並為基於網守的網路建立可靠的基礎。本文包含有關已設定功能的背景技術資訊、設計原則、基本驗證和疑難排解策略。

必須注意的是，在下面的配置中，四台路由器位於同一個LAN中。但是，在實際拓撲中，所有裝置都可能位於網路的不同部分。

開始之前

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

必要條件

本文件沒有特定先決條件。

採用元件

已使用以下裝置測試這些配置：

  • 四個Cisco 2600，採用Cisco IOS®軟體版本12.2.8.5 ENTERPRISE PLUS/H323 MCM

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果在實際網路中工作，請確保在使用任何命令之前瞭解其潛在影響。

設定

本節提供用於設定本文件中所述功能的資訊。

注意：要查詢有關本文檔中使用的命令的其他資訊，請使用命令查詢工具(僅限註冊客戶)。

網關到網守配置的一般要求

在網關能夠從網守獲得正確的地址解析之前，需要滿足幾個條件。

需要驗證兩個重要點，如下所示：

  • 所有網關都應註冊到相應的網守。

  • 所有網守都應具有正確的撥號計畫。

註冊

成功註冊是第一個強制步驟。這些額外因素應予以考慮：

  • 如果網關具有外部交換站(FXS)介面，則在Plain Old Telephone Service(POTS)撥號對等體上，新增no register e164命令。這可避免Cisco錯誤ID CSCdw60626(僅限註冊客戶)中所述的閘道註冊問題。 與使用e164號碼直接註冊FXS埠不同，可以新增網關的區域字首並將路由決策基於區域字首。

  • 通常，最好定義網關的技術字首。雖然技術字首的存在主要影響呼叫路由，但還需要可靠註冊。

有關網關到網守註冊問題的詳細資訊，請參閱排除網守註冊問題。

通話路由

  • 要獲得可靠的呼叫路由，所有網關都應該註冊一些技術字首。技術字首的目的是區分不同型別的呼叫和相應的網關型別。因此，雖然可以使用技術字首進行路由決策，但更好的做法是使用技術字首來區分呼叫的型別和基於區域字首的路由。使用此方法，所有VoIP網關都可以配置相同的技術字首（例如，如本文檔中的示例所示）。

  • 最好顯式配置區域字首的主網關。

  • 將H.323信令繫結到Cisco IOS網關或路由器上的特定IP地址。當Cisco IOS網關有多個活動IP介面時，某些H.323消息可能源自一個IP地址，而其它部分可能引用不同的源地址。如果使用環回介面來標識網關，或者網路中存在防火牆和記帳伺服器，則需要h323-gateway voip bind srcaddr命令。此命令是在Cisco IOS軟體版本12.1.2T中引入的，並記錄在為虛擬介面配置H.323支援中。

有關網守呼叫路由的詳細資訊，請參閱瞭解Cisco IOS H.323網守呼叫路由。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

輸出直譯器工具(僅供註冊客戶使用)支援某些show命令，此工具可讓您檢視show命令輸出的分析。

注意：在嘗試任何debug命令之前，請參閱有關Debug命令的重要資訊。有關下列命令的更多資訊，請參閱本文檔的故障排除命令部分。

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

疑難排解指令

若要疑難排解，請檢查以下幾個要點：

  • 所有網關都要向相應的網守註冊。

  • 網關應具有正確的撥號計畫（配置撥號對等體）。

  • 網守應具有正確的撥號計畫（配置區域字首）。

VoIP呼叫基礎故障排除和調試中介紹的步驟補充了與Gateway-to-Gatekeeper互動相關的debug和show命令的輸出，並且應該用於突出顯示與其他Cisco IOS子系統相關的語音問題。show命令的示例輸出突出顯示上述步驟，debug輸出顯示所有四台路由器的RAS和H225消息序列。

注意：debug h225 asn1命令生成非常大的輸出，因此應謹慎使用。從下面的debug命令中刪除了一些不必要的輸出。

注意：發出debug指令之前，請參閱有關Debug指令的重要資訊。
