Abstract: A system and method for implementing bloom filters in large scale applications is disclosed. The system and method include at least one processor configured to create a plurality of sharded bloom filters based on signatures stored in the memory, perform at least one lookup using the plurality of sharded bloom filters; and output a lookup result in real time.

Abstract: The local address book of a device can be crawled for contact information, which is communicated to an address clearinghouse. The clearinghouse can indicate whether a contact is a participant in a video calling service. If so, an indication can be stored locally indicating that the contact is a participant. Later, during an audio-only call with the contact, an option to escalate the audio-only call to a video call via the video calling service can be presented.

Abstract: A user who is online at multiple devices can be invited to escalate an audio-only call to a video call. The escalation invitation is sent only to, or shown only at, the endpoint device that is involved in the audio-only call. The technologies can support public switched telephone network audio-only calls, and escalation can be performed as a seamless call transition from audio-only to video call.

Abstract: While a device is engaged in an audio-only call, an incoming video call can be received. Video call context information can be included as part of the incoming video call notification, and such information can include an indication that the incoming video call is in fact an escalation of the audio-only call. Based on the call context information, a variety of actions can be taken. For example, the audio-only call can be seamlessly transitioned to the video call.

Abstract: A method for remotely testing an application on a device is disclosed. The method includes connecting a development system to the device. The device is hosted in a remote environment and is not directly accessible to the development system. The development system connects to the device via an agent that is coupled to the device, wherein the agent is configured to receive application data for the device and control signals from the development system and operate the device according to the control signals. The method further includes fetching the collected device data from the device, wherein the agent is configured to collect the device data from the device and the development system retrieves the collected device data from the agent.
