Disable Lobby Bypass
It is possible to enable Skype for Business to use a lobby functionality. Enabling this feature in Skype for Business will result in callers being placed into a lobby rather than being directly admitted to a conference. The callers then need to be invited into the conference. This functionality is set on a Skype for Business Pool, and when configuring a new Pool by default the lobby feature is not enabled, meaning that callers will bypass the lobby and be directly admitted to a conference.
Conferences are scheduled by the Skype for Business T-Server and are used to maintain Genesys call control. When scheduling conferences, the Skype T-Server specifies a LobbyBypass flag that automatically allows all callers to bypass a lobby and be directly admitted to a conference. However, this will cause issues when using the Skype for Business T-Server with a Skype for Business Pool that does not have lobby bypass enabled. Essentially, the Pool is configured to have callers wait in the lobby while T-Server is trying to pass a flag that allows callers to bypass the lobby. In order to prevent such issues a new option is introduced in the Skype for Business T-Server that will make it aware of whether a Pool is configured to use a lobby or has lobby bypass enabled.
Skype T-Server Configuration Options
Sections and options in this chapter are defined in the Annex tab of the Switch object of T-Server.
The option that enables lobby bypass on a Skype for Business Pool is called PstnCallersBypassLobby, and this option is set in the Meeting Configuration. For more details please see https://docs.microsoft.com/en-us/skypeforbusiness/manage/conferencing/meeting-configuration-settings
Limitations and constraints
The Skype T-Server will not be able to schedule conferences for new calls if the settings in Skype for Business and Skype T-Server configuration are inconsistent.
