What is the difference between the CapTel 840 and the CapTel 840i?

There are two main differences:

  1. CapTel 840i is for people with high-speed Internet access / CapTel 840 is for people who do not have high-speed Internet access.
  2. With CapTel 840i, people call your phone number directly and you get captions. / With CapTel 840, callers need to dial the captioning service first and enter your phone number in order for you to get captions*.

They look the same and have most of the same features.

* If you use CapTel 840 in 2-Line mode (optional), people can call your number directly, they do not have to dial the service first.


How do I turn captions on/off using the CapTel 840/840i?

Large Caption Button With CapTel 840i (and CapTel 840 in 2-line mode), you can turn captions on/off at any time during your call by pressing the CAPTIONS button. When the red light around the CAPTIONS button is lit, you will see captions of everything the other party says.

With CapTel 840 (in 1-Line mode), you must turn the CAPTIONS button on before you dial the phone number. You cannot turn captions on during a call. Simply press the CAPTIONS button (red light around the button is lit) before you dial.

Analog Telephone vs. VoIP

What’s the main difference between analog phone service and Voice over IP service? It’s the way the voice signals are delivered. The analog phone service carries signals over a copper wire while the VoIP service delivers these signals over an IP data network.

Analog phone service

An analog telephone is the traditional landline phone service that is found in many homes and businesses today. Also commonly known as Plain Old Telephone Service (POTS), analog phone service allows subscribers to communicate with one another.

These users are connected through a copper wire subscriber loop which runs from a central switch office to many homes and businesses. Each subscriber is assigned a specific phone number, which allows them to contact one another.

How does it work?

An analog telephone system converts the voice signals into electronic signals. These electrical waves travel over the telephone line until they reach the end destination. Because the analog telephone system offers bidirectional communication, these voice signals can travel in two ways – from one telephone to the other, and vice versa.

VoIP phone service

VoIP, which stands for Voice over Internet Protocol, offers phone service over an IP data network – typically the Internet. While analog telephone subscribers receive a connection from their local phone company, VoIP allows for phone service via an Internet connection from a VoIP service provider.

How does it work?

VoIP services convert analog phone signals into digital signals. These can then be delivered over the Internet, from one home or business to another.

Many businesses use VoIP phone service

Businesses frequently use VoIP because it offers a secure and quality service. They can manage calls over their own private networks. Advanced technology has provided new forms of VoIP. It offers more than communication – users can also host web and video conferences with VoIP.


I don't have two telephone lines - can I still use my CapTel 840 phone?

YES, the CapTel 840 works with just one telephone line as well (1-Line mode). Using 2-Line CapTel is purely optional. You can still make and receive telephone calls with captions with 1-Line CapTel. The main different between 1-Line mode and 2-Line mode is in the way that incoming calls get captioned. With 1-Line mode, callers need to dial the captioning service first, then enter your telephone number, in order for you to see captions of the call. With 2-Line CapTel, you can turn the captions on and off at any time, on any incoming or outgoing call.
