Abstract

A system, server, and method of DTMF detection in a VoIP network.

Claims (48)

1. A method comprising:

in response to an identification by an enterprise gateway server that a carrier gateway server cannot orginate an outgoing call, originating the outgoing call by the enterprise gateway server to a mobile device of an enterprise user using number information of an originating party of an incoming call and an indicator identifying a line number dialed by the originating party; and

connecting the incoming call with the outgoing call by the enterprise gateway server.

2. The method of claim 1 , wherein the indicator comprises:

a one or more digit number identifying one of a plurality of telephone lines associated with the incoming call.

3. The method of claim 1 , comprising:

prepending the indicator to the number information.

4. The method of claim 1 , comprising:

replacing a portion of the number information with the indicator.

5. The method of claim 1 , comprising:

transmitting a ring indicator to the mobile device, the ring indicator identifying the line number dialed by the originating party.

6. The method of claim 1 , comprising:

identifying that the incoming call is to be routed to the mobile device based on criteria including one or more of:

a time-of-day, a day-of-week, whether a user associated with the incoming call has badged-in or badged-out, permanent settings, user settings, or administrator settings.

7. The method of claim 1 , comprising:

identifying by the enterprise gateway server that the incoming call for an enterprise user is to be routed to the mobile device based on an enterprise policy.

8. A system comprising:

an enterprise gateway server configured to:

identify that a carrier gateway server cannot originate an outgoing call;

in response to the identification , originate the outgoing call to a mobile device of an enterprise user using number information of an originating party of an incoming call and an indicator to identify a line number dialed by the originating party, and

connect the incoming call with the outgoing call.

9. The apparatus of claim 8 , wherein the indicator comprises:

a one or more digit number to identify one of a plurality of telephone lines associated with the incoming call.

10. The apparatus of claim 8 , wherein the enterprise gateway server or the carrier gateway server is further configured to:

prepend the indicator to the number information.

11. The apparatus of claim 8 , wherein the enterprise gateway server or the carrier gateway server is further configured to:

replace a portion of the number information with the indicator.

12. The apparatus of claim 8 , wherein the enterprise gateway server or the carrier gateway server is further configured to:

transmit a ring indicator to the mobile device, the ring indicator to identify the line number dialed by the originating party.

13. The apparatus of claim 8 , wherein the enterprise gateway server is further configured to:

identify that the incoming call is to be routed to the mobile device based on one or more of:

a time-of-day, a day-of-week, whether a user associated with the incoming call has badged-in or badged-out, permanent settings, user settings, or administrator settings.

14. The apparatus of claim 8 , wherein the enterprise gateway server is further configured to:

identify that the incoming call for an enterprise user is to be routed to the mobile device based on an enterprise policy.

15. A non-transitory computer-readable storage medium configured to store instructions that, when executed by a processor, cause the processor to perform:

in response to an identification by an enterprise gateway server that a carrier gateway server cannot orginate an outgoing call, originating the outgoing call by the enterprise gateway server to a mobile device of an enterprise user using number information of an originating party of an incoming call and an indicator identifying a line number dialed by the originating party; and

connecting the incoming call with the outgoing call by the enterprise gateway server.

16. The non-transitory computer-readable storage medium of claim 15 , wherein the indicator comprises:

a one or more digit number identifying one of a plurality of telephone lines associated with the incoming call.

17. The non-transitory computer-readable storage medium of claim 15 , wherein the instructions further cause the processor to perform:

prepending the indicator to the number information.

18. The non-transitory computer-readable storage medium of claim 15 , wherein the instructions further cause the processor to perform:

replacing a portion of the number information with the indicator.

19. The non-transitory computer-readable storage medium of claim 15 , wherein the instructions further cause the processor to perform:

transmitting a ring indicator to the mobile device, the ring indicator identifying the line number dialed by the originating party.

20. The non-transitory computer-readable storage medium of claim 15 , wherein the instructions further cause the processor to perform:

identifying that the incoming call is to be routed to the mobile device based on criteria including one or more of:

a time-of-day, a day-of-week, whether a user associated with the incoming call has badged-in or badged-out, permanent settings, user settings, or administrator settings.
