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

Microsoft回叫實現與RFC 1570 leavingcisco.com不相容。但是，由於Microsoft撥號網路客戶端的市場份額很大，思科已在Cisco IOS®軟體版本11.3(2)T及更高版本中實施了Microsoft回撥(MSCB)控制協定。

必要條件

需求

嘗試此組態之前，請確保符合以下要求：

  • 配置網路接入伺服器(NAS)以接受來自客戶端的模擬呼叫。回叫是數據機撥入的附加功能。因此，請檢驗此方面是否正常工作。這有助於您進行故障排除。

  • T1/E1電路必須能夠進行撥出。請與您的電話公司(Telco)聯絡以驗證這一點。

採用元件

本檔案中的資訊是根據Cisco IOS軟體版本11.3(2)T和更新版本。

此案例已在使用Windows撥號網路的PC上測試。

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。如果您在即時網路中工作，請確保在使用任何命令之前瞭解其潛在影響。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景理論

按以下順序執行回撥：

  1. PC使用者（客戶端）連線到思科接入伺服器。

  2. 回叫過程在點對點協定(PPP)鏈路控制協定(LCP)階段協商。

  3. 執行PPP身份驗證。

  4. Cisco IOS軟體驗證此使用者或線路的回叫規則，並斷開呼叫方回叫的連線。

  5. 思科接入伺服器撥打客戶端。

有四種型別的MSCB:

  1. 沒有回撥。

  2. 使用者指定的回撥號碼。

  3. 伺服器指定的（預配置的）回撥號碼。

  4. 預配置的回叫號碼的清單。

預設配置沒有回撥（選項1）。 可以配置選項2或3:

  • 本地（如果未使用AAA伺服器）。

  • 在TACACS+或RADIUS使用者設定檔中（如果使用AAA）。

如果配置選項2，系統會提示使用者輸入其回叫號碼。如果配置選項3，則提示符僅提供一個選項，即管理員定義的編號。

思科僅實現MSCB的回叫伺服器功能，而不是回叫客戶端功能。這意味著Cisco路由器只能用作MSCB伺服器，而不能用作MSCB客戶端。此外，思科的MSCB實施要求在客戶端上執行身份驗證。

設定

本節提供用於設定本文件中所述功能的資訊。

配置摘要

要啟用MSCB，必須在接收介面（例如group-async）下啟用ppp callback accept命令。 此外，由於需要身份驗證，您必須啟用密碼身份驗證協定(PAP)或質詢握手身份驗證協定(CHAP)身份驗證： 

ppp authentication chap pap

自動建立兩個聊天指令碼。以下是offhook和callback聊天指令碼：

chat-script offhook "" "ATH1" OK
chat-script callback ABORT ERROR ABORT BUSY "" 
"ATZ" OK "ATDT \T" TIMEOUT60 CONNECT \c

聊天指令碼也會自動應用到正在使用的行：

line 1 24
  script modem-off-hook offhook
  script callback callback

必須授權用戶重新呼叫。您可以根據使用者名稱和密碼資訊的儲存位置，在NAS上或外部AAA伺服器（RADIUS或TACACS+）上本地配置此功能。

這是在Windows回叫的使用者的本地配5551212: 

username callmeback callback-dialstring 5551212 password cisco

此本地配置適用於允許指定自己的回叫號碼的使用者：

username callmeback callback-dialstring "" password cisco

Windows客戶端配置

Windows 95和98客戶端配置

對於Windows 95和98 PC，沒有用於回撥的特殊客戶端配置。訪問伺服器處理連線的回撥功能。Windows 95或98 PC顯示「等待回撥」消息以指示正在進行回撥。

Windows NT和2000客戶端配置

配置這些平台以請求回撥。完成以下步驟以配置它們：

  1. 選擇Start > Programs > Accessories > Communications > Network and Dial-up Connections。

  2. 從選單中選擇Advanced > Dial-up Preferences。

  3. 按一下Callback頁籤訪問回叫功能選單，如圖1所示。

  4. 根據需要配置回叫選項：

    • 若要不使用回撥函式，請按一下No Callback按鈕。

    • 要提示當伺服器提供回叫時應執行的操作，請按一下Ask Me During Dialing When The Server Offers按鈕。

    • 要自動接受回叫優惠，請按一下Always Call Me At The Number(s)Below按鈕，然後從清單中選擇要使用的裝置。

    • 要更改回叫電話號碼，請選擇裝置並按一下Edit按鈕。在Phone Number欄位中輸入號碼（如圖1所示），然後在Call Me Back At對話方塊中按一下OK。

  5. 按一下Phone Number欄位，然後在Call Me Back At對話方塊中輸入該號碼(如圖1所示)。 完成後按一下OK。

  6. 完成後，在「撥號首選項」對話方塊中按一下確定。

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。

  • show isdn active — 顯示有關當前傳入和傳出ISDN呼叫的資訊。使用此命令驗證回撥是否已成功完成。如果回叫成功，show isdn active將呼叫顯示為回叫伺服器上的傳出。

  • show users — 顯示路由器上活動線路的資訊。如果您的Cisco IOS軟體版本支援show caller命令，也可以使用。

  • show dialer — 顯示為按需撥號路由(DDR)配置的介面的一般診斷資訊。

疑難排解

有關debug命令的詳細資訊，請參閱Cisco IOS版本12.0調試命令參考。

  • debug aaa authentication — 顯示有關AAA身份驗證的資訊。

  • debug aaa authorization — 顯示有關AAA授權的資訊。

  • debug callback — 當路由器使用數據機和聊天指令碼在終端線路上回叫時顯示回叫事件。

  • debug modem — 用於觀察接入伺服器上的數據機線路活動。

  • debug ppp [ packet |交涉 |錯誤 | authentication ] — 顯示實施PPP的網際網路中流量和交換的資訊。

    • packet — 顯示正在傳送和接收的PPP資料包。（此命令顯示低級資料包轉儲。）

    • negotiation — 在協商PPP選項時，顯示PPP啟動期間傳輸的PPP資料包。

    • error — 顯示與PPP連線協商和操作關聯的協定錯誤和錯誤統計資訊。

    • authentication — 顯示身份驗證協定消息，包括CHAP和PAP交換。

  • debug chat — 顯示當指示數據機撥出時，訪問伺服器與其內部數據機之間的握手。聊天指令碼是一組期望傳送字串對，用於定義資料終端裝置(DTE)和資料通訊裝置(DCE)裝置之間的握手。

  • debug isdn q931 — 顯示ISDN Q.931（D通道）呼叫建立和拆除消息以及調試。在此案例中，資料機通話是透過公用交換電話網路(PSTN)以語音承載服務方式進行。

  • debug modem csm — 用於排除帶有內部數字數據機的路由器上的呼叫交換模組(CSM)問題。使用此命令，您可以跟蹤切換呼入和撥出呼叫的完整順序。
