  • Patent number: 11934851
    Abstract: Calls run through a virtual desktop infrastructure server are enhanced by testing communication network conditions and selecting, based on the test results, a media channel from a set of supported media channels, including a media channel that is routed through the virtual desktop infrastructure server and encapsulated in a protocol for exchanging data for virtual desktop applications and a more direct media channel that uses a network socket pair between a media server and a personal computing device and bypasses the virtual desktop infrastructure server. In some implementations, call data of multiple types and/or from multiple sources are merged into a single virtual channel of the protocol for exchanging data for virtual desktop applications.
