Abstract
Systems and methods of establishing a communications channel between a first telephony device and a second telephony device obtain information about the capabilities of various data network elements that can be used to establish the communications channel. The information about the elements is used to select a combination of elements that are used to establish the communications channel. A communications channel may also be monitored while it is in use. If the requirements for the channel change, the communications channel may also be changed accordingly. If any of the elements become incapable of providing the required level of service or functionality for a communications channel, the element may be removed from the communications channel.
