  • Patent number: 8571189
    Abstract: In one embodiment, a server may obtain source data for a communication session having a combined audio portion and non-audio portion. As such, the server may actively split the audio portion of the communication session from the non-audio portion of the communication session, and then provide the audio portion (to a first set of one or more phones) over a phone channel and the non-audio portion (to a second set of one or more phones) over a separate data channel. The second set of phones may then obtain and merge the audio portion from the phone channel and the non-audio portion from the data channel to reestablish the full communication session.

  • Publication number: 20130235866
    Abstract: In one embodiment, source data for a communication session may be split into an audio portion for transmission on a phone channel and a non-audio portion for transmission on a data channel. A server and a phone may accordingly establish an audio portion of a communication session on the phone channel. In response to a trigger, the server may provide a push notification on the data channel to the phone, where the push notification is associated with an application executing on the phone that is configured to participate in the non-audio portion of the communication session on the data channel with the server. Upon obtaining the push notification on the data channel during the audio portion on the phone channel, the application may correspondingly activate on the phone to participate in the non-audio portion of the communication session during the phone's participation in the audio portion (e.g., merging the portions).

  • Patent number: 8275892
    Abstract: In one embodiment, a device is connected to a first computer via a first local communication port of the first computer. If the device is configured to autoconnect with a second computer upon connection of the device to the first computer, a remote access session is established between the first computer and the second computer. Low-level local communication from the device is intercepted at the first local communication port of the first computer. The low-level local communication is transmitted from the first computer to the second computer via the remote access session. The low-level local communication is injected to a second local communication port of the second computer to thereby provide an autoconnection of the device to the second computer.
