概要

この文書では、リモート ユーザが次の方法のいずれかを使用してコールを行うための設定例を示します。いずれの場合も、コールバックは V.110 コールを使用して行います。

  • ユーザが GSM 経由で 3640 に接続し、コールバックを要求する。

  • ユーザがモデム経由で 3640 に接続し、コールバックを要求する。

  • ユーザが ISDN(データ)経由で 3640 に接続し、コールバックを要求する。

注:認証、許可、およびアカウンティング(AAA)は、デフォルトではルータで設定されます。ログインするユーザも作成する必要があります。

この例では、コールインおよびコールアウト用に PPP 認証も設定しています。ここでは常にスクリプトを変更して V.110 用にモデムを設定し、ユーザが方式(モデムまたは GSM)を選択できるようにしています。選択した方式に応じてユーザか行う必要がある処理は次のとおりです。

  • コールバック番号に ZDTxxx を使用する(モデムの場合)。

  • コールバック番号に DIxxxx を使用する(GSM の場合)。

ハードウェアおよびソフトウェアのバージョン

この設定は、次のバージョンのソフトウェアおよびハードウェアを使用して開発およびテストされています。

  • V.110 コールバック機能が Cisco IOS® ソフトウェア リリース 12.2(5.2)T 以降で使用可能である。

  • モデム ソフトウェア バージョン 2.7.3.0。
