Abstract
Conventional video call attempts encountering a device inoperable according to a desired capability will fail if the receiving device is unable to complete the call at the desired service level (i.e. video). In addition to frustrating the communication attempts between users, another issue is that resources consumed in the attempted but failed exchange are not recoverable, since the call never completed. Accordingly, configurations herein substantially overcome such shortcomings by providing a fallback mechanism that identifies a service level operable by both the initiating device and the receiving device, and completes the call at a lower service level operable by both devices. The disclosed approach allows a call to complete at an alternate service level (i.e. voice instead of video) rather than failing the call completely, resulting in a source of lost revenue to the service provider (operator).
