什麼是電話系統?What is Phone System?

(PBX) 私人分支 Exchange 是企業內的電話系統。A Private Branch Exchange (PBX) is a phone system within a business. 電話系統提供 PBX 功能,但沒有複雜且昂貴的裝置。Phone System gives you PBX capabilities, but without the complicated and expensive equipment.

[電話系統] 可讓您將現有的內部部署 PBX 系統取代成一組從 Microsoft 365 或 Office 365 提供的功能,這些功能已緊密整合到您的雲端體驗中。Phone System allows you to replace your existing on-premises PBX system with a set of features delivered from Microsoft 365 or Office 365 that is tightly integrated into your cloud experience. 如需這些功能的詳細資訊,請參閱 以下是您在手機系統中所取得的內容For more information about the features, see Here's what you get with Phone System.

電話系統技術Phone System technology

在 Microsoft 團隊和商務用 Skype Online 中,手機系統可啟用雲端的通話控制和 PBX 功能。Phone System enables call control and PBX capabilities in the cloud with Microsoft Teams and Skype for Business Online.

使用電話系統,使用者可以使用小組或商務用 Skype Online 來撥打和接聽通話、轉接通話,以及將通話設為靜音或取消靜音。With Phone System, users can use Teams or Skype for Business Online to place and receive calls, transfer calls, and mute or unmute calls. 電話系統使用者可以按一下其通訊錄中的名稱,然後將小組或商務用 Skype Online 撥打電話給該人。Phone System users can click a name in their address book, and place Teams or Skype for Business Online calls to that person. 若要撥打及接聽電話,電話系統使用者可以使用其行動裝置、膝上型電腦或電腦的耳機,或是使用團隊和商務用 Skype Online 的許多 IP 電話之一。To place and receive calls, Phone System users can use their mobile devices, a headset with a laptop or PC, or one of many IP phones that work with Teams and Skype for Business Online. 電話系統管理員可以管理在通訊、共同作業等所用的同一個主控台中的呼叫選項和設定。Phone System administrators can manage calling options and settings from the same console used for messaging, collaboration, and so on.

貴組織中的使用者之間的呼叫是在手機系統內內部處理,而不會移至公用的交換電話網絡 (PSTN) 。Calls between users in your organization are handled internally within Phone System, and never go to the Public Switched Telephone Network (PSTN). 這適用于您組織中位於不同地理區域的使用者之間的通話,並移除這些內部通話的長途成本。This applies to calls between users in your organization located in different geographical areas, removing long-distance costs on these internal calls.

針對您組織外部的呼叫,Microsoft 會提供多個選項,讓您將電話系統連線至公用交換電話網絡 (PSTN) 。For calls outside your organization, Microsoft provides multiple options for connecting Phone System to the Public Switched Telephone Network (PSTN).

連線到公開交換的電話網絡 (PSTN) Connect to the Public Switched Telephone Network (PSTN)

您可以使用下列兩種方法的其中一種將電話系統連線至 PSTN:Phone System can be connected to the PSTN in one of two ways:

  • 購買 (國內或國內和國際) 的 Microsoft 通話方案。Purchase a Microsoft Calling Plan (domestic or domestic and international). Microsoft 通話方案是一種全式雲端解決方案,擁有 Microsoft 作為 PSTN 運營商。Microsoft Calling Plan is an all-in-the-cloud solution with Microsoft as your PSTN carrier. 如需詳細資訊,請參閱 電話系統和通話方案For more information, see Phone System and Calling Plans.

  • 針對內部部署 PSTN 連線使用您現有的電話結構。Use your existing telephony infrastructure for on-premises PSTN connectivity.

    針對您的團隊使用者,您可以使用直接路由將內部部署電話結構連線至電話系統。For your Teams users, you can connect your on-premises telephony infrastructure to Phone System by using Direct Routing. 如需詳細資訊,請參閱 手機系統 Direct 路由For more information, see Phone System Direct Routing.

含服務的電話系統Phone System with services

電話系統可用於服務和語音信箱,例如:Phone System can be used for services and voicemail, such as:

  • 自動 語音應答可用來為您的組織建立功能表系統,讓外部和內部呼叫者能在系統中移動,以找出並將來電放到貴組織中的公司使用者或部門。Auto attendants - Auto attendants can be used to create a menu system for your organization that lets external and internal callers move through the system to locate and place or transfer calls to company users or departments in your organization. 請參閱 什麼是雲端自動語音應答?。See What are Cloud auto attendants?.

  • 通話 佇列-當某人撥入您組織的電話號碼時,可以使用通話佇列問候語。Call queues - Call queue greetings can be used when someone calls in to a phone number for your organization. 這些問候語包括自動保留通話的功能,以及搜尋下一個可用的呼叫代理程式來處理通話,而呼叫者在通話時接聽的電話。These greetings include the ability to automatically put the calls on hold and the ability to search for the next available call agent to handle the call while the people who call are listening to music on hold. 您可以為組織建立單一或多個通話佇列。You can create single or multiple call queues for your organization. 請參閱 建立雲端通話佇列See Create a Cloud call queue.

  • 語音信箱 -當您取得使用者的電話系統授權時,該使用者就可以取得來電者所留下的語音信箱。Voicemail - When you get a Phone System license for a user, that user is able to get voicemail that has been left by callers. 在您指派電話系統授權及電話號碼之後,就會自動為使用者設定及設定雲端語音信箱。Cloud Voicemail is automatically set up and provisioned for users after you assign a Phone System license and a phone number to them. 請參閱 設定雲端語音信箱See Set up Cloud Voicemail.
