このドキュメントでは、さまざまなメディア ゲートウェイ コントロール プロトコル(MGCP)コール シーケンスの debug mgcp packets キャプチャについて説明します。 各シーケンスは、時系列で表に示します。 表には、メッセージ(MSG)フィールドと DECODE フィールドがあります。 MSG フィールドには実際の debug 出力を示し、DECODE フィールドには該当する debug メッセージの説明を示します。 現在の debug シーケンスは次のとおりです。
このドキュメントは、6 部で構成されるドキュメント セットの第 5 部です。
IOS MGCP ゲートウェイ(アナログ FXO、FXS ポート)を使用した Cisco CallManager 3.x の設定
デバッグ MGCP パケットの例
このドキュメントに関する固有の要件はありません。
この設定は Cisco IOS® ソフトウェア リリース 12.2 イメージの Cisco CallManager 3.0 によって、3.1、および 3.2 およびさまざまなバージョン テストされました。 スクリーン ショットおよび Cisco IOS の設定は、以下のソフトウェア、ハードウェア、およびその他の機器を使用してキャプチャされています。
Cisco VG200/2 X FXS/2 X FXO/1 FastEthernet 10/100 ポート X 1、 Cisco IOS ソフトウェア リリース 12.1(5)T
MCS7835 上で稼働する Cisco CallManager 3.0(5a) X 1
アナログ電話機 X 2
Cisco 7960 IP Phone X 2
このドキュメントの情報は、特定のラボ環境にあるデバイスに基づいて作成されたものです。 このドキュメントで使用するすべてのデバイスは、クリアな(デフォルト)設定で作業を開始しています。 ネットワークが稼働中の場合は、コマンドが及ぼす潜在的な影響を十分に理解しておく必要があります。
Cisco CallManager と Cisco IOS ゲートウェイ間で推奨される互換ソフトウェア バージョンについては、「Cisco CallManager ソフトウェア バージョンの比較」を参照してください。
注: ccm-manager コマンドの拡張に基づき、Cisco IOS ソフトウェア リリース 12.2(11)T 以降が推奨されます。 ccm-manager コマンドには、すべてのルータに(Cisco 2600、3600)と Cisco 音声ゲートウェイ 200(VG200)に、Cisco IOS ソフトウェア リリース 12.1(5)XM 以降が必要です。
Cisco 2600 と 3600 ルータで Cisco IOS ソフトウェア リリース 12.1(3)T 以降を実行している場合、MGCP がサポートされています。 必要なリリースとバージョンは、有効にする必要のある機能によって異なります。 Cisco CallManager サーバで、バージョン 3.0(5)a 以降を実行している必要があります。 ルータの設定は、すべてのタイプのルータで同一です。 Cisco CallManager の設定も、すべてのタイプのルータで同一です。
VG200 は Cisco IOS ソフトウェア リリース 12.1(5)XM1 以降のリリースでサポートされます。 必要なリリースとバージョンは、有効にする必要のある機能によって異なります。 VG200 は Cisco CallManager の以前のリリースでサポートされていますが、バージョン 3.0(5)a 以降が推奨されます。
