Claims (15)

1. The Internet Protocol Voice over Internet Protocol (VoIP), comprising an office switch (OK); external exchange station (CBO); VoIP processor as well as a management tool for setting the VoIP gateway to the MIUR mode (trunk and SD (ear-to-mouth) or offline, to transfer an incoming call from the VoIP processor to OK and an outgoing call from the CBO to the VoIP processor in the MIUR mode, as well as transferring an incoming call from the VoIP processor to the CBO and an outgoing call from the CBO to the VoIP offline. 2. The VoIP gateway of claim 1, wherein the VoIP processor comprises a routing table for converting digits received from the calling party to an extension number, the aforementioned routing table including access code information, entered digits, and Internet protocol information. 3. A method for making a VoIP call between a first VoIP gateway and a second VoIP gateway, wherein the aforementioned first VoIP gateway includes an OK, CBO and VoIP processor and connected to the telephone exchange, the method includes the steps of: (a) sensing the appearance of VoIP -call, (b) determining whether the appeared call is an incoming call or an outgoing call; (c) determining whether the VoIP gateway is set to stand-alone or to the IISS mode if the call is an incoming call; (d) transferring an incoming call from the second VoIP gateway through the VoIP processor to the CBO if the VoIP gateway is set to offline; and (e) if the call that appears is an outgoing call, then transferring the outgoing call to the second gateway through the VoIP processor. 4. The method according to claim 3, in which the incoming call received in the CBO at step (d) is transferred to the telephone exchange OK. 5. The method according to claim 3, further comprising the step of transmitting an incoming call received from the second VoIP gateway through the VoIP processor to OK, if the VoIP gateway is set to MIUR mode. 6. The method according to claim 5, in which an incoming call received in OK is transmitted to the telephone exchange CBO. 7. A VoIP gateway system, comprising: a first telephone exchange having an OK; a second telephone exchange having OK and CBO; a first offline VoIP gateway, the VoIP gateway including a CBO connected to an OK of the first telephone exchange; a second VoIP gateway set to IISC mode, the second VoIP gateway including an OK connected to a CBO of a second telephone exchange and a CBO connected to an OK of a second telephone exchange; as well as an IP network for connecting the first and second VoIP gateways to each other. 8. The VoIP gateway system according to claim 7, in which the first telephone exchange is a telephone switching system, and the second telephone exchange is a traditional private telephone exchange (PT). 9. The VoIP gateway system of claim 7, wherein the second VoIP gateway comprises a routing table for converting the numbers received from the calling party to the extension number, the aforementioned routing table containing information about the access code of the entered digits and information of the Internet protocol. 10. A VoIP gateway system, comprising: first and third telephone exchanges, each having an OK; a second telephone exchange having OK and CBO; a first offline VoIP gateway, the aforementioned VoIP gateway including a CBO connected to an OK of the first telephone exchange; a second VoIP gateway set to IISC mode, wherein the aforementioned second VoIP gateway includes an OK connected to a CBO of a second telephone exchange, as well as a CBO connected to an OK of a second telephone exchange; a third offline VoIP gateway, the aforementioned third VoIP gateway comprising a CBO connected to an OK of the third telephone exchange, as well as an IP network for connecting the first, second and third VoIP gateways. 11. The VoIP gateway system of claim 10, wherein the first and third telephone exchanges are telephone switching systems, and the second telephone exchange is a traditional PST. 12. The VoIP gateway system of claim 10, wherein the second VoIP gateway includes a routing table for converting the numbers received from the calling party to the extension number, the aforementioned routing table containing information about the access code of subscribers registered in the first and third telephone exchanges, about the numbers entered and about the Internet protocol information. 13. A VoIP gateway system, comprising: OK; NWO; VoIP processor; as well as controller means for performing initialization during power-up or reloading of the VoIP gateway; to determine if OK and CBO boards are installed in it, to set the VoIP gateway offline when only the CBO board is installed in it, as well as to transfer an incoming call from the VoIP processor to the CBO board and to transfer the outgoing call to the OK board to the VoIP processor. 14. The VoIP gateway according to claim 13, wherein the controller sets the VoIP gateway to the MIUR mode when both the CBO board and the OK board are installed in it, and also transfers an incoming call from the VoIP processor to the OK board and an outgoing call from CBO boards to the VoIP processor. 15. The VoIP gateway of claim 13, wherein the controller sets the VoIP gateway to the MIUR mode when the E1 / T1 / PR1 card is installed in it, and also transfers an incoming call from the VoIP processor to the OK card and an outgoing call from the CBO boards to the VoIP processor.
