Abstract

A system for (and a method of) selectively establishing communication with one of plural devices associated with a single telephone number is provided. In a preferred embodiment, the system includes a wireless connect unit connected between an enterprise private branch exchange (PBX) network and a public switched telephone network. The wireless connect unit preferably serves as a gateway between the PBX and one or more remote communication devices. The remote devices can be used as standard PBX office telephones for both inbound and outbound telephone calls. Thus, features of the PBX network (e.g., voice mail, direct extension dialing, corporate calling plan, etc.) are available to the remote device even though they are not physically connected to the PBX. When the system receives an incoming call, it can route the call to an office telephone and one or more of the remote devices simultaneously or as desired by the user.

Claims

1. A telecommunication device comprising:

a receiving module for receiving an incoming call from a calling device; and

a programmed processor connected to the receiving module for;

identifying a telephone number associated with a recipient of the incoming call,

using the identified telephone number to form a first communication path between said processor and a first communication device by dialing a first telephone number and a second different communication path between said processor and a second communication device by dialing a second telephone number,

holding the incoming call for a predetermined time until it is determined that the call to the telephone number associated with the recipient has been answered at the first or second communication device,

authenticating the answering one of the first and second communication devices by requesting an acknowledgement signal before forming a completed physical circuit connection between the calling device and the device the recipient has answered; and

routing the incoming call to the answered device using the completed physical circuit connection;

wherein said processor is further programmed to prompt a caller of the incoming call with a menu of call destination options for the recipient of the incoming call and said processor forms at least one of said first communication path and said second communication path in accordance with an option selected by the caller.

2. The device of claim 1, wherein said processor routes the incoming call to a voice mailbox telephone number after the predetermined time expires.

3. The device of claim 2, wherein said predetermined time corresponds to a number of telephone rings.

4. The device of claim 1, wherein the incoming call is routed to a retrieved telephone number associated with a cellular telephone.

5. The device of claim 1, wherein the answered device can operate independently from the telecommunication device.

6. A method of routing a communication from a calling device to a called party associated with a dialed telephone number, the method comprising the steps of:

receiving at a processor the communication made to the dialed telephone number;

holding the received communication in the processor;

identifying a telephone extension using information within the received communication;

using the identified extension to retrieve a first communication device number associated with the called party and a second communication device number associated with the called party;

forming a first communication path between the processor and a first communication device associated with the first communication device number by placing a first call to the first communication device number;

forming a second communication path between the processor and a second communication device associated with the second communication device number by placing a second call to the second communication device number;

determining if the first communication device answered the first call, and if the first call is answered, authenticating the first communication device by requesting an acknowledgement signal from the first communication device and routing the held received communication to the first communication device to form a completed physical circuit connection between the calling device and the first communication device after the acknowledgement signal has been received;

determining if the second communication device answered the second call, and if the second call is answered, authenticating the second communication device by requesting an acknowledgement signal from the second communication device and routing the held received communication to the second communication device to form a completed physical circuit connection between the calling device and the second communication device after the acknowledgement signal has been received; and

prompting a caller of the incoming call with a menu of call destination options for the recipient of the incoming call and forming at least one of said first communication path and said second communication path in accordance with an option selected by the caller.

7. The method of claim 6, further comprising the step of routing the received communication to a voice mailbox number after a predetermined number of rings.

8. The method of claim 6, further comprising the step of routing the received communication to a voice mailbox number after a predetermined time expires.

9. The method of claim 6, wherein the first communication device is a cellular telephone and the second communication device is a landline telephone.

10. The method of claim 6, wherein the first communication device is a personal digital assistant and the second communication device is a landline telephone.

11. A telecommunication apparatus comprising:

a processor programmed to;

receive a communication made to a dialed telephone number;

hold the received communication;

identify a telephone extension using information within the received communication;

use the identified extension to retrieve a first communication device number associated with a called party and a second communication device number associated with the called party;

place a first call to the first communication device number to form a first communication path between the processor and a first communication device associated with the first communication device number;

place a second call to the second communication device number to form a second communication path between the processor and a second communication device associated with the second communication device number;

determine if the first communication device answered the first call, and if the first call is answered, authenticate the first communication device by requesting an acknowledgement signal from the first communication device and route the held received communication to the first communication device to form a completed physical circuit connection between the calling device and the first communication device after the acknowledgement signal has been received; and

determine if the second communication device answered the second call, and if the second call is answered, authenticate the second communication device by requesting an acknowledgement signal from second communication device and route the held received communication to the second communication device to form a completed physical circuit connection between the calling device and the second communication device after the acknowledgement signal has been received;

wherein said processor is further programmed to prompt a caller of the incoming call with a menu of call destination options for the recipient of the incoming call and said processor forms at least one of said first communication path and said second communication path in accordance with an option selected by the caller.
