Multimedia conference call providing adjustable bandwidth for individual communication terminals

摘要

The invention provides multimedia conference calls with communication type conversion for changing types of communication terminals (e.g. from 123 to 107) on one multimedia conference call. In addition, users of communication terminals (106, 107,108) can change communication types during the multimedia conference calls. Also, a set of users can use additional communication types not presently in use by a multimedia conference call to enhance communication among the set of users.
