A conference calling system and method for designating of hosting control from a server device. In a conference call session, one of the client devices may be designated as a host device, wherein that host device is permitted to implement hosting functions. In some instances, the required host device may not be available for the scheduled conference call, but may be available prior to the conference call. The host device may provide hosting control commands to the server device prior to the conference call. Such hosting control commands may include such commands as delegating of hosting control functions in relation to the designated host device. This may allow the presently designated host device to end communications with the server device prior to starting a conference call, while having the server device implement the specific hosting control commands.
