Abstract

A method of operating a captioned telephone, comprising storing analog test data in a captioned telephone memory, dialing a telephone number to a relay gateway, connecting to the relay gateway over a communication network and performing a test of the communication network quality using the test data to determine if the network is sufficient to carry analog data, the test including at least one of transmitting the test data to the relay gateway and receiving test data from the relay gateway via the communication network, wherein the network is one of a POTS network and a VOIP network.

Claims

1. A method of operating a captioned telephone, comprising:

storing a serial number in a captioned telephone memory;

dialing a telephone number to a relay gateway;

connecting to the relay gateway over a communication network;

transmitting a dual tone multi-frequency (DTMF) signal including the serial number to the relay gateway; and

obtaining configuration data associated with the serial number from the relay gateway;

wherein the network is one of a plain old telephone service (POTS) network and an internet protocol (IP) network, and

wherein the configuration data is obtained independent of the network type.

2. A method of operating a relay, the method comprising:

receiving a call from a captioned telephone on a communication network;

receiving an electronic serial number associated with the captioned telephone via a dual tone multi-frequency (DTMF) protocol on the communication network;

obtaining a calling party number used to dial the relay from the communication network;

using the calling party number to determine the location of the captioned telephone;

storing the electronic serial number and the location of the captioned telephone in a relay database;

subsequently receiving a call from the captioned telephone via an internet link to the relay;

receiving the electronic serial number associated with the captioned telephone via an internet protocol (IP) on the communication network; and

associating the serial number received via the IP with a location in the database to identify the location of the captioned telephone.

3. The method of claim 2, wherein the step of receiving a call on a communication link is performed upon receiving a command from a remote platform.

4. The method of claim 2, wherein the step of receiving a call is performed at one of a prescribed interval and a specified time of day.

5. The method of claim 2, further including assigning a jurisdiction to the subsequent phone call placed by the captioned telephone as a function of the location identified.

6. A method of operating a relay, the method comprising:

receiving a call from a captioned telephone on a communication network;

receiving an electronic serial number associated with the captioned telephone via a dual tone multi-frequency (DTMF) protocol on the communication network;

obtaining a calling party number used to dial the relay from the communication network;

using the calling party number to determine the location of the captioned telephone;

storing the electronic serial number and at least one of the calling party number and the location of the captioned telephone in a relay database;

subsequently receiving a call from the captioned telephone via an internet link to the relay;

receiving the electronic serial number and internet protocol (IP) address associated with the captioned telephone via the internet link; and

associating, using the electronic serial number, the IP address received via the internet link with a location in the database to identify the location of the captioned telephone.

7. The method of claim 6, wherein the step of receiving a call on a communication link is performed upon receiving a command from a remote platform.

8. The method of claim 6, wherein the step of receiving a call is performed at one of a prescribed interval and a specified time of day.

9. The method of claim 6, further including assigning a jurisdiction to the subsequent phone call placed by the captioned telephone as a function of the location identified.
