Abstract: A Voice-over-IP (VOIP) system includes a plurality of multi control units (MCUs), in which a first MCU hosts a VOIP session. A method for recommending an MCU to host the VOIP session includes receiving MCU status associated with performance of each of the first MCU and a second MCU included in the VOIP system. The method further includes determining, based on the first and the second MCU status, that hosting the VOIP session on the second MCU can improve a VOIP system metric. According to the method, a recommendation is communicated to transfer hosting the VOIP session to the second MCU.

Abstract: A computer-implemented method, system and computer program product for a conference call moderator to conduct a conference call between a plurality of participants. At least some of the conference call participants are grouped by location. A participant within each group is identified to act as a domestic focus for that group and is notified of its assigned role. For each group, the conference call moderator disconnects from all participants in the group except for the participant that has been assigned the role of domestic focus. For each group, the conference call is then routed through the assigned domestic focus. Such a grouping may, for example, occur as a result of a degradation in call quality or may be based on the number of call participants. This solution preferably off-loads some of the conference call processing to the domestic focus, thereby alleviating the workload faced by the overall conference call moderator.

Abstract: A conference call management method, system, and computer program product include inferring an Internet Protocol (IP) address of a new user requesting to join a call including at least one other user, inferring a codec to stream an emulated network pattern for the call if the new user were to join the call, measuring a call quality perceived by the at least one other user in the call while the emulated codec is run on the call, and measuring an impact on the call quality in a case that the new user joins the call based on the perceived call quality and the network pattern.

Abstract: A Voice-over-IP (VOIP) system includes a plurality of multi-control units (MCUs). A first MCU in the VOIP system hosts a first VOIP session that joins a plurality of conference devices. Based on an impact metric being acceptable, and an alternate MCU accepting to host the VOIP session, the system joins the plurality of conference devices to a replacement VOIP session hosted on the alternate MCU.

Abstract: A method, system, and/or computer program product improve Voice over Internet Protocol (VoIP) call quality during a VoIP session. A VoIP session is established between an initial focus VoIP node and multiple slave VoIP nodes, where the initial focus VoIP node uses a first type of codec for the VoIP session. A user focus code score (UFCS) describes a VoIP call quality for each of the nodes based on predetermined network conditions related to use of a certain type of codec and nodal hardware specifications. The UFCSs are ranked to identify a highest-ranked VoIP node. The highest-ranked VoIP node is reclassified as a new focus VoIP node for the VoIP session, and the initial focus VoIP node is reclassified as a slave VoIP node. Thereafter, there is a simultaneous switching of 1) the focus and 2) the type of codec used in the VoIP session.
