Abstract
The present disclosure relates to communications, and more particularly, to a seamless interworking of call control between autonomous systems. In an illustrative embodiment, an electronic device is provided. The electronic device can be connected to multiple autonomous networks, for example, a private network through a Private Branch Exchange and a public network through a Public Switched Telephone Network. The user device can have multiple network interfaces. Alternatively, there can be one network interface to access the autonomous networks. These networks each can provide unique collaboration services. Collaboration services can include, but are not limited to, associations, roles, availability and features. The electronic device can setup connections and initialize a call through both networks. Through the device, each of the networks can add or delete participants to the call under the direction of the user. The networks can also provide the user device with suitable feature keys.
