Abstract
A computer telephony interface (CTI) applications computer interfaces to a Internet telephony system which utilizes, preferably, the session initiation protocol (SIP). In one preferred technique, an additional pass through server is added to connect end users to their associated SIP proxy server, and to connect a CTI applications computer to the system.
Claims21
A system comprising:
- a proxy server to receive and store a first table for address translation and registration of plural terminals associated therewith, each terminal being capable of participating in a telephone call to be implemented over a packet switching data network, said proxy server being connected to a data network;
- and
- a pass through server connected to said data network and through which information between said proxy server and any of said terminals passes, said pass through server including a second table that mirrors said first table, said pass through server also being configured to communicate information to and from an applications computer, said applications computer including software to at least control or monitor calls among said terminals over said data network.
A method comprising:
- transmitting a call initiation message to a proxy server or a pass through server;
- in response to receipt of said call initiation message, transmitting from said pass through server or said proxy server a fake inbound call message to a calling terminal specified in said call initiation message;
- and
- in response to said fake inbound call message, initiating an Internet telephone call from said calling terminal.
1 more element
An article of manufacture comprising:
- a machine-accessible medium having associated data, wherein the data, when accessed, results in a machine performing;
- receiving commands from an applications computer to implement computer telephony integration (CTI) functions;
- communicating with a pass through server or a proxy server to convey parameters received in said command from said applications computer;
- and
- causing one or more terminals to initiate Internet telephone calls in response thereto.
