Abstract

A method and system of an embodiment of the present invention may involve receiving an invite message at a network port of a device to initiate a communication session with the device; identifying an address associated with the invite message; when the address corresponds to a first address, performing a first session initiation process to establish first communications via an audio port of the device; and when the address corresponds to a second address, performing a second session initiation process to establish second communications via the audio port of the device; wherein the second session initiation process differs from the first session initiation process. In addition, access to the audio port may involve determining a priority of the invite message; rejecting the invite message when the priority of the invite message is inferior relative to a priority of a current dialog; and accepting the invite message when the priority of the invite request is superior to the priority of the current dialog.

Claims

1. A method, comprising:

receiving an invite message at a network port of a device to initiate a communication session with the device;

identifying an address associated with the invite message;

when the address corresponds to a first address, performing a first session initiation process to establish first communications via an audio port of the device; and

when the address corresponds to a second address, performing a second session initiation process to establish second communications via the audio port of the device;

wherein the second session initiation process differs from the first session initiation process in that the first session initiation process includes providing an alert signal at the audio port in response to receiving the invite message while the second session initiation process does not provide the alert signal in response to receiving the invite message.

2. The method of claim 1, wherein the first communications are two-way audio communications and the second communications are one of telemetry communications and test/verification communications.

3. The method of claim 1, wherein the device comprises a SIP device with a user agent, and the invite message comprises a SIP INVITE message.

4. The method of claim 1, wherein the network port comprises a packet switched network interface.

5. The method of claim 1, wherein an analog user interface is coupled to the audio port of the device.

6. The method of claim 1, further comprising:

determining a priority of the invite message;

rejecting the invite message when the priority of the invite message is inferior relative to a priority of a current dialog; and

accepting the invite message when the priority of the invite message is superior to the priority of the current dialog.

7. A Non-transitory computer readable media comprising code to perform the acts of the method of claim 1.

8. A device, comprising:

an audio port that communicates with a user interface;

a network port that communicates with a remote element; and

a user agent that is configured to;

receive an invite message at the network port to initiate a communication session with the device;

identify an address associated with the invite message;

when the address corresponds to a first address, perform a first session initiation process to establish first communications via an audio port of the device; and

when the address corresponds to a second address, perform a second session initiation process to establish second communications via the audio port of the device;

wherein the second session initiation process differs from the first session initiation process in that the first session initiation process includes providing an alert signal at the audio port in response to receiving the invite message while the second session initiation process does not provide the alert signal in response to receiving the invite message.

9. The device of claim 8, wherein the remote element comprises a SIP server.

10. The device of claim 8, wherein the remote element comprises a remote SIP user agent.

11. The device of claim 8, wherein the first communications are two-way audio communications and the second communications are one of telemetry communications and test/verification communications.

12. The device of claim 8, wherein the device comprises a SIP device with a user agent, and the invite message comprises a SIP INVITE message.

13. The device of claim 8, wherein the network port comprises a packet switched network interface.

14. The device of claim 8, wherein an analog user interface is coupled to the audio port of the device.

15. The device of claim 8, wherein the user agent is configured to:

determine a priority of the invite message;

reject the invite message when the priority of the invite message is inferior relative to a priority of a current dialog; and

accept the invite message when the priority of the invite message is superior to the priority of the current dialog.

16. A method, comprising:

transmitting an invite message with an associated address;

wherein the invite message is transmitted to initiate a communication session with a device; and

accessing an audio port of the device based on the associated address;

wherein when the address corresponds to a first address, a first session initiation process is performed to establish first communications via the audio port of the device; and

wherein when the address corresponds to a second address, a second session initiation process is performed to establish second communications via the audio port of the device;

wherein the second session initiation process differs from the first session initiation process in that the first session initiation process includes providing an alert signal at the audio port in response to receiving the invite message while the second session initiation process does not provide the alert signal in response to receiving the invite message.

17. The method of claim 16, wherein the first communications are two-way audio communications and the second communications are one of telemetry communications and test/verification communications.

18. The method of claim 16, wherein the device comprises a SIP device with a user agent, and the invite message comprises a SIP INVITE message.

19. The method of claim 16, wherein the invite message is transmitted to a network port of the device, wherein the network port comprises a packet switched network interface.

20. The method of claim 16, wherein an analog user interface is coupled to the audio port of the device.

21. A Non-transitory computer readable media comprising code to perform the acts of the method of claim 16.
