Patent ID: 7023839

Claim:
A telecommunications system, comprising: a packet switched network; one or more telephony devices coupled to said packet switched network, said one or more telephony devices configured to communicate using one or more coding algorithms; and a bandwidth allocation server configured to cause a renegotiation of which of said coding algorithms said one or more telephony devices communicates with while said one or more telephony devices are communicating using a predetermined coding algorithm; wherein said bandwidth allocation sever is adapted to transmit one or more renegotiation signals to one or more telephony devices involved in a communication a telephony device seeks to join and one or more telephony devices involved in another communication, wherein said renegotiation is based on a modified demand (MD), wherein said modified demand is determined based on a demand (D) calculated by dividing available network bandwidth by the number of idle users, a percentage of voice load allowed (VLA), and a percentage of calls expected to be activated (EA).
