Abstract: A method and system for SMS assisted call establishment to anchor selected cellular calls in a Voice over Internet Protocol (VoIP) or an IP Multi-Media Subsystem (IMS) network employs a mobile handset application client to interrupt selected cellular call initiations and transmit requested destination number and additional information by short message service (SMS) to call control application server. A call placed to the certain call establishment number will be processed by the application server based on information received through SMS, the application server will complete a call connection to the destination number and as a result, the call signalling path through the application server in the VoIP or IMS network will be established to facilitate the provision of advanced call control services. All call establishment steps will be done seamlessly from the prospective of the user of the mobile handset.

Abstract: A method and system for enhanced call control through SMS based protocol employs a mobile handset optionally equipped with application client to send call control commands and additional information by short message service (SMS) to call control application server. Such commands will be processed by the application server based on information received through SMS and as a result the application server will provide different call control functionality such as but not limited to call establishment between different subscribers, 3d party call control features, different types of conference and transfer, adding or removal terminals from the controlled group, manipulation with specific calling group like simultaneous call (SIM) group or haunting group, association of controlled terminal with specific personal access numbers (DID) and others. All call control steps could be done seamlessly by mobile application from the prospective of the user of the mobile handset.

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).

Abstract: The endpoint status notification system includes an address book of network user's names and their associated endpoints. A user selects a personal list of contacts from the address book and receives an instant message alert upon every occurrence of a reportable event for one of the contacts on the list. Alerts are informational status messages pertaining to the contact and are delivered unbeknownst to the contact. Preferably, alerts are popup windows displayed for a preset amount of time, however audible alerts are available in lieu of or in combination with the popups. Reportable events are selected by the user for each of the contacts on the list and may differ from contact to contact. Simultaneous with the alert, the user may be provided a call-control option related to the reportable event and pertaining to the contact. If selected, the call-control option causes a telecommunication function to immediately occur.
