Captioned Telephone (CapTel)

Talk, listen and read captions
on the phone!

Captioned Telephone (CapTel) enables you to hear, read captions and speak during phone calls. This service is designed for people who are Deaf or Hard of Hearing.

Read below to learn more about our CapTel service!

How Does Captioned Telephone (CapTel) Work?

Placing a call on a CapTel phone is just like using a standard phone, but even better.

Just dial the number of the person you want to call and the CapTel phone automatically connects to a captioning service.*


You speak directly to the other party on the CapTel phone.


The other party talks directly to you while the captioner listens.


The captioner transcribes the other party’s voiced message into captions.


You listen and read the captions on the CapTel phone.

* This only applies to 2-line CapTel 840. For one-line CapTel 840, all incoming calls must be routed to the CapTel service first by dialing 877-243-2823 then enter the CapTel user’s phone number.
