Synchronization of client application data between POTS telephone and content portal through PSTN

A system for synchronizing multiple devices, comprising:

• a controller;
• a memory coupled to the controller and comprising computer readable program instructions that when executed by the controller causes the controller to perform operations comprising:
• registering the multiple devices as being associated with each other responsive to user input at a content portal;
• receiving application data that have changed from a first one of the devices at the content portal;
• determining at the content portal that the first one of the devices is associated with a second one of the devices;
• initiating communication at the content portal with the second one of the devices;
• and
• communicating the application data that have changed from the content portal to the second one of the devices so as to synchronize the application data that have changed between the first and the second one of the devices;
• wherein the first one of the devices is a plain old telephone system phone comprising a modem;
• and
• wherein receiving the application data comprises receiving the application data that have changed that have been transmitted by the modem over a dial-up communication connection established between the plain old telephone system phone and the content portal through a public switched telephone network;
• wherein the operations further comprise:
• programmatically determining at the content portal that the plain old telephone system phone is associated with client application data in a portal database of the content portal;
• wherein programmatically determining at the content portal that the plain old telephone system phone is associated with the client application data comprises:
• programmatically determining at the content portal that at least some of the client application data in the portal database has changed;
• determining at the content portal that the changed client application data is associated with the plain old telephone system phone;
• and
• programmatically dialing from the content portal a telephone number associated with the plain old telephone system phone in response to the at least some of the client application data that has changed in the portal database;
• and
• wherein the operations further comprise:
• programmatically synchronizing the client application data between the plain old telephone system phone and the portal database comprising communicating the client application data in the portal database that has changed to the plain old telephone system phone through the public switched telephone network over the dial-up communication connection.

A computer program product for synchronizing multiple devices, comprising:

• a non-transitory computer readable medium comprising computer readable program instructions that when executed by a controller causes the controller to perform operations comprising:
• registering the multiple devices as being associated with each other responsive to user input at a content portal;
• receiving application data that have changed from a first one of the devices at the content portal;
• determining at the content portal that the first one of the devices is associated with a second one of the devices;
• initiating communication at the content portal with the second one of the devices;
• and
• communicating the application data that have changed from the content portal to the second one of the devices so as to synchronize the application data that have changed between the first and the second one of the devices;
• wherein the first one of the devices is a plain old telephone system phone comprising a modem;
• and
• wherein receiving the application data comprises receiving the application data that have changed that have been transmitted by the modem over a dial-up communication connection established between the plain old telephone system phone and the content portal through a public switched telephone network;
• wherein the operations further comprise:
• programmatically determining at the content portal that the plain old telephone system phone is associated with client application data in a portal database of the content portal;
• wherein programmatically determining at the content portal that the plain old telephone system phone is associated with the client application data comprises:
• programmatically determining at the content portal that at least some of the client application data in the portal database has changed;
• determining at the content portal that the changed client application data is associated with the plain old telephone system phone;
• and
• programmatically dialing from the content portal a telephone number associated with the plain old telephone system phone in response to the at least some of the client application data that has changed in the portal database;
• and
• wherein the operations further comprise:
• programmatically synchronizing the client application data between the plain old telephone system phone and the portal database comprising communicating the client application data in the portal database that has changed to the plain old telephone system phone through the public switched telephone network over the dial-up communication connection.
