Abstract:
1. A method allowing communication between a first terminal and a second terminal, wherein the first terminal and the second terminal participate in a video-conference, a web-conference, or a teleconference, the method comprising: establishing, with a processing device, a packet switched connection between the first terminal and a gateway; establishing, with the processing device, a circuit switched H.320 connection between the second terminal and the gateway, the circuit switched connection being established from a first number of ISDN B-channels; receiving, with the processing device from the first terminal, a first data rate reflecting a receiving data rate capability of the first terminal; receiving, with the processing device from the second terminal, a second data rate reflecting a data rate of the circuit switched H.320 connection; comparing, with the processing device, said first data rate with the second data rate; determining, with the processing device, that the first data rate is lower than the second data rate; disconnecting, with the processing device, a second number of the first number of the ISDN B-channels so that the packet switched connection has a higher data rate than the circuit switched H.320 connection; executing, with the processing device, a resynchronization procedure on remaining ISDN B-channels to form the circuit switched H.320 connection; and determining, with the processing device, said second number of the ISDN B-channels to disconnect by converting said first data rate to a multiple of a fixed data rate and subtracting said multiple from an amount of the first number of ISDN B-channels.
