Abstract

A system and associated processes to provide interactive public branch exchange (PBX) processes. The PBX processes including: session initiation protocol (SIP) processes, application processes, and an interface with signaling process. The media processes cause the machine to: perform an audio/video play process, perform a record process, and perform a mixing process.

Claims

1. An apparatus to operate as a session initiation protocol (SIP) client device comprising:

a processor executing applications to provide the SIP client device with localized application level intelligence for announcement, conferencing, IVR presence and a speech services engine in addition to being a SIP user agent;

a memory coupled to the processor, the processor operates to execute a plurality of public branch exchange (PBX) processes in the memory that interact together to provide a distributed PBX platform to provide multi-party conferencing without a centralized media server, wherein the plurality of PBX processes include;

a plurality of SIP stack processes comprising an SIP user agent process, a plurality of SIP server processes;

an SIP proxy process, an SIP redirect process, and an SIP registrar process,

a plurality of application processes;

a plurality of media processing processes including;

an audio/video play process;

a mixing process;

a record process;

an encoding process;

a decoding process;

an encrypting process; and

a decrypting process;

a local media interface; and

a signaling interface.

2. The apparatus of claim 1, the plurality of application processes comprising:

a conferencing control process; and

a call agent/interactive voice response (IVR) process.

3. The apparatus of claim 1, further comprising:

one of a universal serial bus (USB) device, a headset device and an SIP telephone device to interact with the plurality of PBX processes.

4. A non-transitory machine accessible medium containing instructions that, when executed, cause a machine to:

execute applications to provide a session initiation protocol (SIP) client device with localized application level intelligence for announcement, conferencing, IVR presence and a speech services engine in addition to being a SIP user agent

perform a plurality of interactive public branch exchange (PBX) processes, the plurality of PBX processes including;

a plurality of session initiation protocol (SIP) processes;

a plurality of application processes to provide multi-party conferencing without a centralized media server, wherein the SIP processes further cause the machine to;

perform an SIP user agent process, perform a plurality of SIP server processes, perform an SIP proxy process, perform an SIP redirect process, and perform an SIP registrar process; and

an interface with signaling process, wherein the plurality of media processes further cause the machine to;

perform an audio/video play process;

perform a record process; and

perform a mixing process.

5. The machine accessible medium of claim 4, further containing instructions that, when executed, cause the machine to:

perform media processing processes; and

interface with local media.

6. The machine accessible medium of claim 4, wherein the application processes further cause the machine to:

perform a conferencing control process; and

perform a call agent/interactive voice response (UVR) process.

7. The machine accessible medium of claim 4, wherein the plurality of media processes further cause the machine to:

perform an encoding process;

perform a decoding process;

perform an encrypting process; and

perform a decrypting process.

8. The machine accessible medium of claim 4, further including instructions to cause the machine to:

interface with one of a universal serial bus (USB) device, a headset device and an SIP telephone device to interact with the plurality of PBX processes.
