Abstract: An apparatus and method for receiving a request from a first device requesting a communication session with a second device; coordinating with a communication gateway and a registration database to determine whether the second device is registered with the communication server; enabling transmission of a first notification to the second device in response to determining that the second device is registered with the communication server, or enabling transmission of a second notification to the second device in response to determining that the second device is not registered with the communication server, the first notification and the second notification notifying the second device of the request for the communication session; receiving an indication of acceptance of the communication session from the second device; and coordinating with the communication gateway to start the communication session between the first device and the second device in response to receiving the indication of acceptance.

Abstract: An apparatus and method for receiving, at a communication server, a web-based request for a real-time communication session, selecting, at the communication server, a number of applications based on information included in the web-based request to support the real-time communication session, the number of applications being from among the plurality of applications running on the one or more application servers, communicating with the one or more application servers to enable provision of the number of applications for the real-time communication session, and enabling the real-time communication session between a first device and a second device.

Abstract: A method performed by a communication server includes receiving a request from a first network entity to set up a communication session between a first user at a first device and a second user at a second device, wherein the first network entity is registered with the communication server, in response to the request, generating a token, wherein the token is configured to grant access to the communication session, sending the token to the first network entity, after sending the token to the first network entity, receiving the token from the first user at the first device, and causing the communication session to be set up between the first user at the first device and the second user at the second device according to the token.
