Abstract

A system for facilitating 9-1-1 service delivery to internet telephony customers is provided. The system includes a server device for receiving a 9-1-1 call from a user device via a data network, where the 9-1-1 call are based on “9-1-1” digits dialed at the user device. The server device is configured to forward the received 9-1-1 call to an operator services interface operatively connected to the server device.

Claims

1-21. -21. (canceled)

22. A method, comprising:

receiving, from a telephony device and by a server device, a set of dialed digits that correspond to an emergency telephone number;

replacing, by the server device, the set of dialed digits with a set of dialed digits that correspond to an operator services number; and

forwarding, by the server device, a call, associated with the set of dialed digits, where the forwarding is based on the operator services number.

23. The method of claim 22, further comprising:

determining whether the telephony device is a mobile telephony device or a fixed location telephony device,

where the replacing and forwarding are performed upon determining that the telephony device is a mobile telephony device.

24. The method of claim 23, where the determining is based on a profile associated with the telephony device.

25. The method of claim 22, further comprising:

determining whether the telephony device is a mobile telephony device or a fixed location telephony device; and

attempting, when the mobile telephony device is a fixed location telephony device, to resolve an Automatic Number Identification (ANI), associated with the telephony device,

where the replacing and forwarding are performed upon failing to resolve the ANI.

26. The method of claim 22, where the set of dialed digits include “

9-1-1.”

27. The method of claim 22, where the telephony device includes a Voice over Internet Protocol device.

28. The method of claim 22, where the forwarding includes:

forwarding the call, using the operator services number, via a Public Switched Telephone Network.

29. A non-transitory computer-readable memory device storing instructions that are executable by one or more processors of a server device, the instructions comprising:

one or more instructions to receive, from a telephony device, a set of dialed digits that correspond to an emergency telephone number;

one or more instructions to replace the set of dialed digits with a set of dialed digits that correspond to an operator services number; and

one or more instructions to forward a call, associated with the set of dialed digits, where the forwarding is based on the operator services number.

30. The non-transitory computer-readable memory device of claim 29, further comprising:

one or more instructions to determine whether the telephony device is a mobile telephony device or a fixed location telephony device,

where the one or more instructions to replace and forward include one or more instructions to replace and forward upon determining that the telephony device is a mobile telephony device.

31. The non-transitory computer-readable memory device of claim 30, where the one or more instructions to determine include one or more instructions to determine based on a profile associated with the telephony device.

32. The non-transitory computer-readable memory device of claim 29, further comprising:

one or more instructions to determine whether the telephony device is a mobile telephony device or a fixed location telephony device; and

one ore more instructions to attempt, when the mobile telephony device is a fixed location telephony device, to resolve an Automatic Number Identification (ANI), associated with the telephony device,

where the one or more instructions to replace and forward include one or more instructions to replace and forward upon failing to resolve the ANI.

33. The non-transitory computer-readable memory device of claim 29, where the set of dialed digits include “

9-1-1.”

34. The non-transitory computer-readable memory device of claim 29, where the one or more instructions to forward include:

one or more instructions to forward the call, using the operator services number, via a Public Switched Telephone Network.

35. A method, comprising:

receiving, from a telephony device, a set of dialed digits that correspond to an emergency telephone number;

determining, in response to receiving the set of dialed digits, whether the telephony device is a mobile device or a fixed device;

processing the set of dialed digits in a first manner when the telephony device is a mobile device; and

processing the set of dialed digits in a second manner when the telephony device is a fixed device.

36. The method of claim 35, where processing the set of dialed digits in the first manner includes:

replacing the set of dialed digits with another set of digits; and

forwarding a call, associated with the set of dialed digits, using the other set of digits.

37. The method of claim 36, where the other set of digits includes a set of digits associated with operator services.

38. The method of claim 35, where processing the set of dialed digits in the second manner includes:

forwarding a call, associated with the set of dialed digits, using the set of dialed digits.

39. The method of claim 35, where the set of dialed digits include “

9-1-1.”

40. The method of claim 35, where the telephony device includes a Voice over Internet Protocol device.

41. The method of claim 35, where the determining is based on a profile associated with the telephony device.
