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

identifying, by the device, an address associated with the invite message,

the address corresponding to a type of communication session associated with the communication session to be initiated;

determining, by the device, whether an existing communication session is established via an audio port of the device;

determining, by the device and when the existing communication session is established via the audio port, whether the existing communication session is on hold; and

performing, by the device, a session initiation process to establish the communication session via the audio port when the existing communication session is not established via the audio port or when the existing communication session is on hold.

2. The method of claim 1, where the communication session is one of a telemetry communications communication session or a verification communication session.

3. The method of claim 1, where the session initiation process does not provide an alert signal based on the network port of the device receiving the invite message.

4. The method of claim 1, further comprising:

determining whether an audio communication session is established via the audio port.

5. The method of claim 4, further comprising:

exchanging bidirectional audio data during the communication session when the audio communication session is not established via the audio port.

6. The method of claim 4, further comprising:

determining whether the audio communication session is on hold when the audio communication session is established via the audio port.

7. The method of claim 6, further comprising:

determining that the audio communication session is not on hold;

receiving audio data from the audio communication session and the communication session; and

transmitting the audio data to the audio communication session and the communication session.

8. The method of claim 1, where the device comprises a session initiation protocol (SIP) device with a user agent, and the invite message comprises a SIP invite message.

9. The method of claim 1, where the network port comprises a packet switched network interface.

10. A non-transitory computer readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to;

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

identify an address associated with the invite message,

the address corresponding to a type of communication session associated with the communication session to be initiated;

determine whether an existing communication session is established via an audio port of the device;

determine, when the existing communication session is established via the audio port, whether the existing communication session is on hold; and

perform a session initiation process to establish the communication session via the audio port when the existing communication session is not established via the audio port or when the existing communication session is on hold.

11. The non-transitory computer readable medium of claim 10, where the instructions further comprise:

one or more instructions that, when executed by the one or more processors, cause the one or more processors to;

determine that no audio communication session is established via the audio port; and

exchange bidirectional audio data during the communication session.

12. The non-transitory computer readable medium of claim 10, where the instructions further comprise:

one or more instructions that, when executed by the one or more processors, cause the one or more processors to;

determine that an audio communication session is established via the audio port; and

determine whether the audio communication session is on hold.

13. A system, comprising:

at least one processor to;

receive an invite message to initiate a communication session,

the invite message being associated with an address that corresponds to a type of communication session associated with the communication session to be initiated;

access an audio port of the system based on the address;

determine whether an existing communication session is established via the audio port;

determine, when the existing communication session is established via the audio port, whether the existing communication session is on hold; and

perform a session initiation process to establish the communication session via the audio port when the existing communication session is not established via the audio port or when the existing communication session is on hold.

14. The system of claim 13, where the communication session is one of a telemetry communication session or a verification communication session.

15. The system of claim 13, where the session initiation process does not provide an alert signal based on the invite message.

16. The system of claim 15, where the alert signal is a ringing signal.

17. The system of claim 13, where the at least one processor is further to:

determine whether an audio communication session is established via the audio port.

18. The system of claim 13, where the at least one processor is further to:

determine that no audio communication session is established via the audio port; and

exchange bidirectional audio data during the communication session.

19. The system of claim 13, where the at least one processor is further to:

determine that an audio communication session is established via the audio port; and

determine whether the audio communication session is on hold.

20. The system of claim 19, where the at least one processor is further to:

determine that the audio communication session is not on hold;

receive audio data from the audio communication session and the communication session; and

transmit the audio data to the audio communication session and the communication session.

21. The system of claim 13, where the invite message comprises a session initiation protocol (SIP) invite message.
