Abstract

A telecommunications system includes a personal computer having a unified communication system including a presence application and a cellular telephone network identifier operably coupled to the unified communication system and configured to identify a cellular telephone network of multiple parties; and a cellular network gateway appliance operably coupled to the personal computer and configured to allow the unified communication system to make a telephone call via an associated cellular network and identified by the cellular telephone network identifier.

Claims

1. A telecommunication method comprising:

identifying cellular networks with an instant messaging service for each of a plurality of users;

identifying called and calling parties'"'"' cellular telephone networks, at least one of said called and calling party being one of said plurality of users;

creating a first call leg to a called party cellular telephone via a first gateway associated with the identified first cellular network; and

creating a second call leg to a calling party cellular telephone via a second gateway associated with the identified second cellular network, wherein said cellular networks are identified in one or more buddy lists, and a server creates said first call leg and said second call leg.

2. A telecommunications method in accordance with claim 1, wherein identified said called and calling parties cellular telephone networks are different networks and said first call leg and said second call leg are connected through said first gateway and said second gateway over a local area network.

3. A telecommunications method in accordance with claim 1, wherein

each of said first call leg and said second call leg being selected ones of said identified cellular networks, said first gateway and said second gateway being a gateway to a respective identified said cellular network.

4. A telecommunications system, comprising:

a local area network (LAN) including a plurality of user devices having unified communications applications and a plurality of cellular network gateways;

means interfaceable via the unified communications application for identifying a cellular network associated with a called party and a calling party, said interfaceable means including an instant messaging system identifying cellular networks associated with a plurality of users, ones of said plurality of cellular network gateways being a gateway to a respective identified said cellular network, wherein said cellular networks are identified in one or more buddy lists;

means for creating a first call leg to a called party cellular telephone via a first gateway associated with the identified first cellular network;

means for creating a second call leg to a calling party cellular telephone via a second gateway associated with the identified second cellular network; and

means for connecting the first leg and the second leg such that the called party and said calling party communicate via the LAN.

5. A telecommunications system in accordance with claim 4, said identifying means including presence status display means displaying cellular networks associated with a plurality of users, ones of said plurality of cellular network gateways being a gateway to a respective displayed said cellular network.

6. A telecommunications system in accordance with claim 5, wherein said interfaceable means includes a presence system including said instant messaging system.

7. A telecommunications system, comprising:

a personal computer having a unified communication system including a presence application and a cellular telephone network identifier operably coupled to the unified communication system and configured to identify a cellular telephone network of multiple parties; and

a cellular network gateway appliance operably coupled to the personal computer and configured to allow the unified communication system to make a telephone call via an associated cellular network and identified by the cellular telephone network identifier, wherein said presence application is Instant Messaging and associated said cellular networks are identified in one or more buddy lists.

8. A telecommunications system in accordance with claim 7, wherein said cellular gateway appliance couples to the personal computer via a serial bus, the personal computer presence application identifying cellular networks associated with each of the multiple parties, said cellular network gateway selectively directing calls over said associated cellular network whenever a call is to any of said multiple parties identified as also associated with said associated cellular network.

9. A telecommunications system in accordance with claim 7, wherein said cellular gateway appliance couples to the personal computer via a local area network.

10. A telecommunications system in accordance with claim 9, further including a second cellular gateway appliance that couples to the personal computer via the local area network and wherein the unified communication system is configured to call out to parties on via the local area network and first and second cellular gateway appliances, the personal computer presence application identifying cellular networks associated with each of the multiple parties, said cellular network gateways selectively directing calls over respective associated cellular networks whenever a call with any of said multiple parties is identified as also associated with one of said respective associated cellular networks.

11. A telecommunications method, comprising:

identifying cellular networks with a presence server for each of a plurality of users;

initiating a call from a presence client;

calling out from said presence server to cellular telephones on separate cellular networks via cellular gateway appliances on a local area network; and

connecting the calls via the local area network such that the cellular telephones are deemed to be on a same cellular network, wherein said presence server is an instant messaging (IM) server on a unified messaging system and said presence client is an IM client identifying the cellular networks associated with the cellular telephones.

12. A telecommunications method in accordance with claim 11 said calling out further comprising automatically calling out from a party on a contact list having cellular network identifying indicia, wherein the called party cellular telephone and the calling party cellular telephone are on different cellular networks.

13. A telecommunications system, comprising:

means for identifying cellular networks with a presence server for each of a plurality of users;

means for receiving call initiation from a presence client;

means for calling out from said presence server to cellular telephones on separate cellular networks via cellular gateway appliances on a local area network; and

means for connecting the calls via the local area network such that the cellular telephones are deemed to be on a same cellular network, wherein said presence server is an instant messaging (IM) server on a unified messaging system and said presence client is an IM client identifying the cellular networks associated with the cellular telephones.

14. A telecommunications system in accordance with claim 13 said calling out means further comprising means for automatically calling out from a party on a contact list having cellular network identifying indicia, wherein the called party cellular telephone and the calling party cellular telephone are on different cellular networks.
