Abstract

A method of, and means for accomplishing the method, optimizing system resources in a network (102) using packetized voice telephony consists of the following steps: determining (302) that a packetized voice call from an originating gateway (104) terminates at a non-human voice interface system (108), wherein the packetized voice call is assigned a specified high priority level; and transmitting (304) signaling to cause the originating gateway (104) to transmit the packetized voice call to the non-human voice interface system (108) at a lower priority than the specified high priority level.

Claims

1. A method of optimizing system resources in a network using packetized voice telephony comprising:

determining that a packetized voice call from an originating gateway terminates at a non-human voice interface system, wherein the packetized voice call is assigned a specified high priority level; and

transmitting signaling to cause the originating gateway to transmit the packetized voice call to the non-human voice interface system at a lower priority than the specified high priority level.

2. The method of claim 1 wherein the non-human voice interface system comprises a voice messaging system.

3. The method of claim 1 wherein the determining includes determining whether a subscriber at a terminating gateway intended to be a terminating end of the packetized voice call subscribes to a voice messaging system.

4. The method of claim 1 wherein the non-human voice interface system comprises an interactive voice response system.

5. The method of claim 1 further comprising transmitting signaling to cause the originating gateway to compress the packetized voice call.

6. The method of claim 1 wherein the specified high priority level comprises a real time priority level to ensure that the packetized voice call will occur substantially in real time.

7. The method of claim 1 wherein the determining includes detecting whether the packetized voice call has been answered at a terminating gateway intended to be a terminating end of the packetized voice call within a prescribed number of rings at the terminating gateway.

8. The method of claim 7 wherein the detecting comprises detecting whether a ring timeout has occurred at the terminating gateway within the prescribed number of rings at the terminating gateway.

9. The method of claim 7 wherein the detecting comprises detecting whether an absence of an offhook at the terminating gateway within the prescribed number of rings at the terminating gateway.

10. The method of claim 1 wherein the transmitting step comprises automatically transmitting the signaling to cause the originating gateway to transmit the packetized voice call to the non-human voice interface system at the lower priority than the specified high priority level.

11. The method of claim 1 wherein the transmitting step comprises selectively transmitting the signaling to cause the originating gateway to transmit the packetized voice call to the non-human voice interface system at the lower priority than the specified high priority level.

13. The method of claim 12 wherein the non-human voice interface system comprises a voicemail system.

14. The method of claim 12 wherein the non-human voice interface system comprises a interactive voice response system.

15. The method of claim 12 further comprising compressing, prior to the transmitting step, the packetized voice call.

16. The method of claim 12 wherein the specified high priority level comprises a real time priority level to ensure that the packetized voice call will occur substantially in real time.

18. The system of claim 17 wherein the means for determining includes means for determining whether a subscriber at a terminating gateway intended to be a terminating end of the packetized voice call subscribes to a voice messaging system.

19. The system of claim 17 further comprising means for transmitting signaling to cause the originating gateway to compress the packetized voice call.

20. The system of claim 19 wherein the means for determining includes means for detecting whether the packetized voice call has been answered at a terminating gateway intended to be a terminating end of the packetized voice call within a prescribed number of rings at the terminating gateway.

21. The system of claim 19 wherein the means for transmitting comprises means for automatically transmitting the signaling to cause the originating gateway to transmit the packetized voice call to the non-human voice interface system at the lower priority than the specified high priority level.

22. The system of claim 17 wherein the means for transmitting comprises means for selectively transmitting the signaling to cause the originating gateway to transmit the packetized voice call to the non-human voice interface system at the lower priority than the specified high priority level.

24. The system of claim 23 further comprising means for compressing the packetized voice call.

12. A method of optimizing system resources in a network using packetized voice telephony comprising:

receiving an indication that a packetized voice call has terminated at a non-human voice interface system, wherein the packetized voice call is assigned a specified high priority level;

re-prioritizing the packetized voice call to a lower priority level than the specified high priority level; and

transmitting the packetized voice call to the non-human voice interface system at the lower priority level.

17. A system for optimizing system resources in a network using packetized voice telephony comprising:

means for determining that a packetized voice call from an originating gateway terminates at a non-human voice interface system, wherein the packetized voice call is assigned a specified high priority level;

and

means for transmitting signaling to cause the originating gateway to transmit the packetized voice call to the non-human voice interface system at a lower priority than the specified high priority level.

23. A system for optimizing system resources in a network using packetized voice telephony comprising:

means for receiving an indication that a packetized voice call has terminated at a non-human voice interface system, wherein the packetized voice call is assigned a specified high priority level;

means for re-prioritizing the packetized voice call to a lower priority level than the specified high priority level; and

means for transmitting the packetized voice call to the non-human voice interface system at the lower priority level.
