Voice Carry-Over (VCO) is the perfect solution for you if you like to talk and read captions during your phone calls.  When the other party speaks to you, the relay agent serves as your “ears” and types all the words that are spoken and background sounds, if any, on your VCO phone or text telephone/teletypewriter (TTY).  Then you speak directly back to the other party. 

This service is designed for the people who are Deaf or Hard of Hearing.

This relay service is available in English-to-English and Spanish-to-Spanish.

The TRS Customer Profile allows you to store your relay call preferences and helps speed up call processing.

How Does Voice Carry-Over (VCO) Work?

It’s a snap!

Just dial 711 (or 800-735-4423 for English or 866-479-7569 for Spanish) on your VCO phone or text telephone/teletypewriter (TTY).  The relay agent will answer with “Relay New Hampshire”.

Provide the area code and telephone number you wish to call and say “Go Ahead”.  The relay agent will dial the number and connect you to the other party.

Other VCO Features

Please specify to the relay agent the VCO call type you would like to make.


The relay agent types what you, the VCO user, says to the TTY user.  The TTY user types directly to your VCO phone.


The relay agent serves as “ears” for both VCO users by typing what is said to both VCO phones and/or TTYs.

Two-Line VCO

Two-line VCO allows you, the VCO user, to use one telephone line for speaking directly to another party, and another telephone line to receive the other party’s typed responses.  This feature provides a more natural flow of conversation and eliminates the need to say “Go Ahead” (“GA”).
