Abstract

A method of routing a data transmission includes the first step of receiving a destination number of a data transmission. The destination number corresponds to a first communication network, e.g. voice grade analog telephone lines. In the second method step, a determination is made as to whether the data transmission should be routed through a second communication network, e.g. a digital network. In the third method step, the data transmission is routed through the second communication network if the second step so determines.

Claims

1. A method of routing a data transmission comprising the steps of:

(a) receiving a destination number of said data transmission corresponding to a destination device directly reachable on a first communication network, said destination number not directly corresponding to a number on a second communication network;

(b) determining whether said data transmission should be routed through said second communication network and not through said first communication network; and

(c) routing said data transmission through said second communication network if step (b) determines said data transmission should be routed through said second communication network, wherein said data transmission is routed through said second communication network even though said data transmission is capable of being routed through said first communication network.

2. The method of claim 1, wherein step (a) comprises the steps of:

(a1) isolating a device which produced said data transmission from said first communication network; and

(a2) intercepting said destination number of said data transmission when said device attempts to connect to said first communication network.

3. The method of claim 1, wherein the determination in step (b) is made in accordance with locally held information.

4. The method of claim 3, wherein the locally held information comprises communication network exchange information.

5. The method of claim 3, wherein the locally held information comprises selective access information.

6. The method of claim 1, wherein said data transmission is one of a facsimile data transmission, a voice data transmission, and a modem data transmission.

7. The method of claim 1, wherein the destination number is not capable of being directly routable through the second communication network to a destination device, but is converted to a number that is capable of being routed through the second communication network when step b) determines that said data transmission should be routed through said second communication network.

8. The method of claim 7, wherein the data transmission is routed from a source device to a first device connected to the second communication network using the converted number, and wherein the destination number is included in a data packet transmitted to a second device that is also connected to the second communication network, and

wherein the second device uses the destination number to connect with the destination device to complete the data transmission.

9. The method of claim 8, wherein the destination device is not directly reachable on the second communication network.

10. A method of routing a fax transmission comprising the steps of:

(a) receiving a destination number of said data transmission corresponding to a destination device directly reachable on a first communication networks, said destination number not directly corresponding to a destination on said second communication network;

(b) determining whether said data transmission should be routed through a second communication network and not through said first communication network; and

(c) routing said data transmission through said second communication network if step (b) determines said data transmission should be routed through said second communication network, wherein said data transmission is routed through said second communication network even though said data transmission is capable of being routed from said first communication network.

11. The method of claim 10, wherein step (a) comprises the steps of:

(a1) isolating a device which produced said facsimile transmission from said first communication network; and

(a2) intercepting said destination number of said facsimile transmission when said device attempts to connect to said first communication network.

12. The method of claim 10, wherein the determination in step (b) is made in accordance with locally held information.

13. The method of claim 12, wherein the locally held information comprises communication network exchange information.

14. The method of claim 12, wherein the locally held information comprises selective access information.

15. A method of routing a facsimile transmission comprising the steps of:

(a) detecting an off-hook signal from a facsimile device;

(b) pre-dialing a plurality of digits of a telephone number corresponding to a pre-determined communication network, the plurality of digits corresponding to a portion of said telephone number;

(c) determining whether a connection to the pre-determined communication network should be established; and

(d) dialing a remainder of digits of said telephone number of said predetermined communication network if step (c) determines that said connection should be established.

16. The method of claim 15, wherein step (a) further comprises:

(1) connecting a receive portion of a telephone line to a receive portion of said facsimile device, whereby said facsimile device detects a dial tone; and

(2) isolating a transmit portion of said telephone line from a transmit portion of said facsimile device.

17. The method of claim 15, wherein step (c) is coincident with step (b).

20. The method of claim 15, further comprising the step of, if step c) determines that said connection should not be established to the pre-determined communication network, dialing the remainder of digits of said telephone number of said predetermined communication network and routing the facsimile transmission through a telephone network different from the predetermined communication network.

18. A method of routing a facsimile transmitted from a facsimile device comprising the steps of:

(a) determining whether said facsimile device has been taken off-hook, and if said facsimile device has been taken off hook,

(1) pre-dialing a telephone number of a pre-determined communication network;

(2) parsing a destination number received from said facsimile device;

(3) determining whether said destination number contains a local control command, and if said destination number contains said local control command,

(i) processing said local control command; and

(ii) returning to step (a);

(4) processing said destination number to route a transmission of said facsimile device;

(5) monitoring said transmission;

(6) updating a statistical database with information corresponding to said transmission; and

(7) returning to step (a);

(b) determining whether a ring signal is present on a telephone line coupled to said facsimile device, and if said ring signal is present,

(1) connecting said facsimile device to said telephone line;

(2) monitoring an incoming facsimile transmission; and

(3) updating the statistical database with information corresponding to said incoming facsimile transmission; and

(4) returning to step (a);

(c) determining whether a callback should be processed, and if said callback should be processed;

(1) processing said callback; and

(2) returning to step (a);

and

(d) returning to step (a).

19. The method of claim 18, wherein step (a)(4) comprises:

(i) receiving a destination telephone number corresponding to a first communication network;

(ii) determining whether said destination number is excluded from being routed through a second communication network, and if said destination number is not excluded;

(A) determining if said facsimile transmission should be routed through said second communication network, and if said facsimile transmission should be routed through said second communication network;

(1) routing said facsimile transmission through said second communication network; and

(2) skipping steps (iii) and (iv);

(iii) determining whether said facsimile transmission should be routed through an alternate service network, and if said facsimile transmission should be routed through said alternate service network,

(A) routing said facsimile transmission through said alternate service network; and

(B) skipping step (iv);

(iv) routing said facsimile transmission through said first communication network.
