System and an improved method for controlling multimedia features and services in a sip-based phones
First Claim
1. A system for controlling multimedia features and supplementary services in SIP based phones, the system comprising:
- at least one user agent client (UAC), operable to request desired data using a Reliable Data Transfer (RDT) message as an expanded Session Initiation Protocol (SIP) and check whether the data is correctly received; and
at least one user agent server (UAS), operable to combine the requested data with information indicating whether the data is correctly transmitted, using the RDT message as the expanded SIP, and transmit the resultant data; and
a SIP terminal which supports two way communication with another SIP entity in real-time and also supports both signaling and media; and
at least a Proxy server capable of contacting at least one client or the next-hop server and passes the call request further; and
at least a Redirect Server capable of accepting SIP requests; and
at least a Location Server capable of providing information about a caller'"'"'s possible locations and redirect to the proxy serversa Reliable Data Transfer (RDT) message processor capable to convert information on requested data into an RDT message and extract the requested data from a received RDT message;
a data controller, operable to send information on requested data to the RDT message processor and transfer a transformed RDT message to the SIP stack, and send an RDT message received from the SIP stack to the RDT message processor and transfer information on the extracted data to the data application unit.a data application unit operable to process or store the extracted data;
a Session Initiation Protocol (SIP) stack operable to communicate an SIP message including an RDT message between the server;

8. An improved method for controlling multimedia features and supplementary services in SIP based phones, the method comprising the steps of:
-
generating a caller application which initiates and sends SIP requests through least one user agent client (UAC); and receiving and responding to the SIP requests on the behalf of the clients through at least one user agent server (UAS); and contacting one or more clients or the next hop server and passing the call requests further through at least one proxy server; and accepting the SIP requests and mapping the addresses into zero or more new addresses and returns those addresses to the clients by at least one Redirect Server;
wherein;the multimedia services and supplementary services includes; Call forwarding, Call blocking or Ignoring calls, Call return, Call trace, Last Call Duration, Recent Number List, Caller ID, Compatibility with Windows 2000/XP operating systems, Proxy Authorization support, Address Book, Volume Visualization, Easy User Installation, Click to call. Music player, Business Processing, Realtime online adding of funds, Caller ID blocking, Priority ringing and Conference calling.
