解決方案1
您可以將客戶端配置為繞過代理,並直接轉到代理設定例外部分中的Call Manager;導航到「控制面板」>「網路和Internet」>「Internet選項」>「連線」>「LAN設定」>「高級」
您可以先按星號(*)定義例外,然後按域、單個IP地址或範圍定義例外;例如*.MY.Domain;192.168.1.1 ;192.168.1.12-14 .
解決方案2
配置Proxy以重定向來自Jabber客戶端的流量以重定向到適當的Call Manager。
解決方案3
從Windows客戶端刪除代理配置,然後讓來自Jabber的HTTP GET方法繞過代理和來自PC的所有其他流量。這取決於從客戶端到Call Manager的網路流量,如果中間的基礎設施通過Web快取通訊協定(WCCP)傳送Web流量,則此狀態將無效。
驗證
檢查工作站上的代理設定。
步驟1.從命令列驗證代理配置;導覽至命令提示,然後執行命令netsh winhttp show proxy
步驟2.您可以導覽至Control Panel > Network and Internet > Internet Options > Connections > LAN Settings。
步驟3.運行命令「regedit」,然後導航至HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Internet Settings
