Abstract

Providing a single number presentation to the party called by a dual-mode phone. The operation of the cellular side of a dual-mode phone is altered such that when the user attempts to place an outgoing call using the cellular phone, the call is redirected to a preprogrammed incoming phone number associated with the enterprise. When the enterprise PBX answers this call, the dual-mode phone transmits the desired number to the enterprise PBX. The enterprise PBX then places the call to the desired number, and in the process transmits the caller-id information assigned to the dual-mode phone.

Claims

1. A method of operating a dual-mode phone comprising:

detecting an attempt to place a call through a cellular connection to a target number,

storing the target number,

initiating a cellular connection to a predetermined number,

once connected, transmitting the stored target number to a controller at the predetermined number,

the controller receiving the target number,

the controller identifying the calling dual-mode phone,

the controller retrieving caller-id information associated with the dual-mode phone,

the controller calling the target number and supplying the caller-id information associated with the dual-mode phone, and

connecting the dual-mode phone to the call placed to the target number.

2. The method of claim 1 where the step of transmitting the stored target number includes the step of encoding the digits comprising the stored target number.

3. The method of claim 2 where the step of encoding the digits comprising the stored target number comprises adding framing.

4. The method of claim 2 where the step of encoding the digits comprising the stored target number comprises adding check digits.

5. The method of claim 2 where the step of encoding the digits comprising the stored target number comprises repeating digits.

6. The method of claim 2 where the step of encoding the digits comprising the stored target number comprises adding authentication.

7. The method of claim 1 where the step of transmitting the stored target number is repeated a preset number of times.

8. The method of claim 1 where the step of transmitting the stored target number is repeated for a preset period of time.

9. The method of claim 1 where the step of the controller identifying the calling dual-mode phone comprises the steps of:

retrieving the caller-id information associated with the incoming call from the dual-mode phone, and

comparing the caller-id information against a list of authorized numbers.
