Patent ID: 8203594

Claim:
A method of avoiding call failure, comprising: determining a set of capability features of communications devices, the communications devices including an initiating device and a receiving device, the capability features indicative of a service level of each of the communications devices; receiving an incoming call from the initiating device, the incoming call having an expected service level, the call directed to the receiving device; concluding that an insufficiency exists between the capability features of the calling devices, the insufficiency resulting in an inability to complete the call at the expected service level, concluding that an insufficiency exists further comprising: recognizing an ISDN trigger corresponding to a non-video enabled device; identifying a video telephony call having an integrated audio and video signal; bifurcating the integrated audio and video signals into an audio component and a video component; capturing the signals from the video component; decoding the audio component to carry the audio portion of the call; and buffering the captured video signals for subsequent delivery by a user compliant video medium; and invoking fallback logic operable to complete the call at a service level common to the set of capability features of the communications devices.
