Abstract: The invention pertains to a call management service for a communications system, configured to automatically: receive telephone call data identifying a destination end point and identifying a source end point; initiate a call-back telephone call to said source end point to set-up a first call leg responsive to receiving said telephone call data; initiate a telephone call to said destination end point to set-up a second call leg; combine said first and second call legs together thereby to provide voice communication between said source and destination end points; and transmit call leg status signals for said voice communication over a separate real-time communications connections signalling link to a communications client associated with at least one of said end points.

Abstract: A status proxy server having a full bandwidth connection with a media server and wireless connection with a mobile end user device, receives SIP or similar protocol structured data; maintains a status indicator representative of the received structured data; and communicating at time intervals an update of the status indicator to the mobile end user device.
