Components Used for Dial-In Conferencing

Lync Server 2010
 

Topic Last Modified: 2010-12-12

The following Microsoft Lync Server 2010 communications software components are used for dial-in conferencing:

  • Application service   Application service provides a platform for deploying, hosting, and managing unified communications (UC) applications. Dial-in conferencing uses two unified communications (UC) applications that require Application service: Conferencing Attendant and Conferencing Announcement. Application service is installed and activated by default on every Front End Server in a Front End pool and on every Standard Edition server when you deploy a Conferencing workload and select the dial-in conferencing option.
  • Conferencing Attendant application   Conferencing Attendant is a unified communications application that accepts public switched telephone network (PSTN) calls, plays prompts, and joins the calls to an A/V conference. Conferencing Attendant is installed and activated by default when you deploy a Conferencing workload and select the dial-in conferencing option.
  • Conferencing Announcement application   Conferencing Announcement is a unified communications application that plays tones and prompts to PSTN participants on certain actions, such as when participants join or leave a conference, participants are muted or unmuted, someone enters the conference lobby, or the conference is locked or unlocked. Conferencing Announcement also supports dual-tone multifrequency (DTMF) commands from the phone keypad. Conferencing Announcement is automatically installed and activated by default when you deploy a Conferencing workload and select the dial-in conferencing option.
  • Dial-in Conferencing Settings Web page   The Dial-in Conferencing Settings Webpage displays conference dial-in numbers with their available languages, assigned conference information (that is, for meetings that do not need to be scheduled), and in-conference DTMF controls, and supports management of personal identification number (PIN) and assigned conferencing information. The Dial-in Conferencing Settings webpage is automatically installed as part of Web Services.
  • Lync Server 2010 Mediation Server and PSTN gateway   Dial-in conferencing requires a Mediation Server to translate signaling (and media, in some configurations) between Lync Server and the PSTN gateway, and a PSTN gateway to translate signaling and media between the Mediation Server and the PSTN. For dial-in conferencing, you must deploy at least one Mediation Server and at least one of the following:
    • A PSTN gateway
    • An IP-PBX
    • A Session Border Controller (SBC) for an Internet telephony service provider to which you connect by configuring a SIP trunk
    noteNote:
    If you are also deploying Enterprise Voice, Mediation Servers and PSTN gateways are part of the Enterprise Voice deployment. If you are not deploying Enterprise Voice, you need to deploy at least one Mediation Server and at least one PSTN gateway, IP-PBX, or SBC for dial-in conferencing.
  • File store   File store is used for recorded name audio files. File Store is a standard component in every Enterprise Edition or Standard Edition deployment.
  • User store   User store is used to store user Lync Server 2010 PINs. PINs are hashed. The User store is a standard component in every Enterprise Edition or Standard Edition deployment.
  • Lync Server Control Panel   Some dial-in settings can be configured by using Lync Server Control Panel.
  • Lync Server Management Shell   All dial-in settings can be configured by using Lync Server Management Shell cmdlets. Lync Server Management Shell cmdlets are available for deploying, configuring, running, monitoring, and troubleshooting Conferencing Attendant and Conferencing Announcement. For details about specific cmdlets, see Lync Server Management Shell documentation.
