See full text

A hybrid communication system estimates a quality of service (QoS) for a plurality of session channels available to couple a first device on a first network with a second device on a second network. A first session channel is selected, from the plurality of session channels, that has a highest estimated QoS of all the plurality of session channels over a first time interval. The devices are instructed to establish a hybrid media session using the first session channel. During the hybrid media session the estimated QoS for the plurality of session channels is monitored. Responsive to the monitoring, a second session channel is selected, from the plurality of session channels, that has a highest estimated QoS of all the plurality of session channels over a second time interval. Responsive to the selecting, the devices are instructed establish the hybrid media session using the second session channel.
