Abstract: A method and system for interactive call control for calls and connections created in different communication networks provide a solution of controlling communication connections originated from different terminals and sources such as landline and mobile phones, soft and hardware based SIP phones, Skype, gTalk or similar communication tools by using the same unified user interface. This method and system employ a desktop computer, tablet or even mobile device equipped with cross-platform application client to send call control commands and to monitor the state of controlled connections through encrypted communication channel with the application server. This server will abstract each terminal in unified way and represent it as a standard SIP enabled device which could be controlled remotely from desktop terminal (DT).
