Abstract

An analog and digital communication system establishes a connection between a plain old telephone service (POTS) device and a destination device. The system includes a customer appliance that includes multiple ports, an internal power source device, a subscriber identification module (SIM) card, an electronic control unit, an analog to digital convertor, and a processor device. At least one of the ports are operably connected to the POTS device. A controller communicates remotely with the customer appliance via the network to provide routing of the telephone call between the POTS device and the destination device. The controller is configured to at least one of transmit the telephone call or receive the telephone call via a closest public switched telephone network (PSTN) handoff or via an internal customer appliance network establishing a connection between the customer appliance and a second customer appliance.

Claims (37)

1 . A system for establishing a connection between a plain old telephone service (POTS) device and a destination device, the system comprising:

a first network appliance configured to communicate with a second network appliance via a private network, the first network appliance including:

at least one port physically and communicatively coupled to the POTS device; and

a processing device configured to:

facilitate dialing for the POTS device; and

packetize and depacketize signals associated with a telephone call between the POTS device and the destination device; and

a controller in a datacenter, the controller configured to, via the private network:

communicate with the first network appliance and the second network appliance; and

route the telephone call between the POTS device and the destination device via the second network appliance, the second network appliance including at least one port physically and communicatively coupled to the destination device.

2 . The system of claim 1 , further comprising a remote storage in communication with the controller, the remote storage including an indication of at least one network appliance.

3 . The system of claim 1 , wherein the first network appliance further includes at least one of: (i) a modem, (ii) an access point providing a wide area network (WAN), (iii) a voice gateway, and (iv) a 66 block.

4 . The system of claim 1 , wherein the controller is further configured to facilitate a best quality of the telephone call to ensure a quality of service (QoS).

5 . The system of claim 1 , wherein the first network appliance is configured to provide an end-to-end encryption of the telephone call.

6 . The system of claim 1 , wherein the at least one port physically and communicatively coupled to the POTS device includes multiple ports and the first network appliance is operably connected to a TI line via a given port of the multiple ports.

7 . The system of claim 1 , wherein the first network appliance is configured to provide notification of the telephone call to a user via a text message or an email.

8 . The system of claim 1 , wherein the controller is further configured to provide a variable bit rate of the signals, the variable bit rate determined based on at least one of network connectivity and bandwidth.

9 . The system of claim 1 , wherein the POTS device is a first POTS device, wherein the at least one port physically and communicatively coupled to the POTS device includes multiple ports and a given port of the multiple ports is operably connected to a second POTS device, and wherein the controller is further configured to facilitate routing of telephone calls between the first POTS device and the second POTS device.

10 . The system of claim 1 , wherein the private network is a bidirectional network.

11 . The system of claim 1 , wherein the private network including a bidirectional tunnel.

12 . The system of claim 1 , wherein the controller is further configured to communicate remotely with the first network appliance via the private network.

13 . A system for establishing a connection between a plain old telephone service (POTS) device and a destination device, the system comprising:

a first network appliance and a second network appliance;

the first network appliance configured to communicate with the second network appliance via a private network and including:

at least one port physically and communicatively coupled to the POTS device; and

a processing device configured to:

facilitate dialing for the POTS device; and

packetize and depacketize signals associated with a telephone call between the POTS device and the destination device;

the second network appliance including:

at least one port physically and communicatively coupled to the destination device; and

a processing device configured to packetize and depacketize the signals associated with the telephone call; and

a controller in a datacenter, the controller configured to, via the private network:

communicate with the first network appliance and the second network appliance; and

route the telephone call between the POTS device and the destination device via the second network appliance.

14 . The system of claim 13 , wherein the controller is further configured to facilitate a best quality of the telephone call to ensure a quality of service (QoS).

15 . The system of claim 13 , further comprising a remote storage in communication with the controller, the remote storage including an indication of at least one network appliance.

16 . The system of claim 13 , wherein the private network is a bidirectional network.

17 . The system of claim 13 , wherein the private network includes a bidirectional tunnel.
