Telephony Control Server support different types of conferences: Station-controlled conferences (large conference), meet-me conferences and ad hoc conferences.
Telephony Control Server supports a central Media server and branch office Media servers. For reasons of reliability, backup Media servers can also be configured. The following applies:
The route list defines how the conference request is routed. The central Media server can be configured to be the default destination if all other options to secure the Media server in the branch fail – e. g. due to overload or unavailability.
Conference lines for a business group must be assigned to the same Media server; distributing the various conferees of a single conference among different Media servers is not supported.
A conference shall always be created on the Media server which is the primary Media server of the conference creator. If the primary Media server is not available, the backup Media server will be used.
The backup Media server is only activated when the central Media server has been ascertained as being unavailable.
Meet-me conferences are scheduled in advance. They require a separate conference application – e. g. the conference portal of the Media Server.
An ad-hoc conference is an unscheduled conference that may be created without pre-planning. The Lotus Sametime Unified Telephony user selects either multiple contacts from the contact list or creates manually a list of participants using directory access, creates the conference and starts it immediately. Ad-hoc conferences require a separate conference application – e. g. the conference portal of the Media Server.
Station-controlled Conferences (Large Conference)
Via station-controlled conferences, Telephony Control Server users can stage a conference with a total of 48 participants. The maximum number of conference participants can be restricted by the performance of the Media Server used or by creating the Business Group Service. With the Media Server you can use the maximum number of conference participants. Station-controlled conferences are set up as required (ad-hoc). The participants of a station-controlled conference can be members of the same or of different business groups or be participants in the public network.
RTP System Parameters for Station-Controlled Conferences
The behavior of station-controlled conferences is influenced by different, system-wide settings – by so-called Resilient Telco Platform system parameters (RTP system parameters). Changing one of these settings influences the behavior for all business groups and their members.
