Abstract: Methods and system for automating conferencing in a communication session are provided herein. In some embodiments, a method for automating conferencing in a communication session includes establishing a communication session between a first end-user device and a second end-user device; receiving a first notification message from the first end-user device indicating that the communication session is at least one of visible or joinable by one or more devices associated with the first end-user device, wherein the one or more devices are associated with the first end-user device when the one or more devices are one of (i) pre-registered and stored with an association to the first end-user device, (ii) pre-authenticated to tether the one or more devices to the first end-user device, or (iii) pre-associated with a same user account profile; and sending a second notification message to the one or more devices associated with the first end-user device.

Abstract: An IP telephony system allows a user to register a telephony device that receives its native telephony service from a different telephony service provider as an extension telephone. The user can then place calls through the IP telephony system using the extension telephone. Such calls may or may not be established using the extension telephone's native telephony service provider.

Abstract: Methods and system for automating conferencing in a communication session are provided herein. In some embodiments, a method for automating conferencing in a communication session includes detecting an established communication session between a first end-user device and a second end-user device, notifying a third end-user device associated with the first user device that the established communication session is available to be joined, receiving a request from the third end-user device to join the communication session, and establishing a conference session with the first end-user device, the second-end user device, and the third end-user device.

Abstract: An IP telephony system allows users of the IP telephony system to register extension telephony devices with the IP telephony system. An extension telephony device is one that is provided with service by a separate telephony service provider. Once an extension telephony device is registered, a user can obtain communications services from the IP telephony system using the extension telephony device. A extension telephony device may be tied to a user's main telephony services account with the IP telephony system such that when the user obtains communications services from the IP telephony system using an extension telephony device, the user will be billed for those communications services through the user's main account.
