Michigan Relay Service: VCO (Voice Carry Over)

Placing VCO Calls Using a TTY

1. Using your TTY, dial 711 or the toll-free number for your state.
2. After the Communication Assistant (CA) answers and identifies Relay, type “VCO PLS GA.”
3. Wait for the CA to type, “VCO ON GA” indicating that Voice Carry Over has been activated.
4. Pick up the handset and speak to the CA providing the number of the person you wish to call, and any additional instructions. Say “GA” or “Go Ahead” and immediately place the handset back onto the TTY.
5. The CA will ask the person you are calling if he/she is familiar with Voice Carry Over. If the person is not, the CA will explain how VCO works before the conversation begins.
6. The CA types the response of the other person for you to read on your TTY screen. When you see “GA,” it is your turn to respond by picking up the handset and speaking to the other person.
7. When you are ready for the other person to respond, say “GA” and place the handset back on the TTY. Turn-taking continues in this manner until the call is complete.

Placing Calls with 2-Line VCO

Requires the use of two telephone lines, one of which must have 3-way conferencing capabilities.

1. Using your TTY, dial 711 or the toll-free number for your state.
2. When the CA answers the call, inform the CA that this will be a 2-Line VCO call. You may do so by either speaking to the CA or typing “2LVCO PLS GA.”
3. Instruct the CA to dial your voice telephone number.
4. The CA will dial your voice number and type back: “Dialing XXX-XXX-XXXX, Ring 1, 2....”
5. Answer your voice line with your voice. Ask if the CA can hear you. The CA will type back a response.
6. Ask the CA to hold while you use your voice phone to create a conference call and dial the number of the person you wish to call.
7. Immediately connect the conference using the “hold,” “switch hook,” “flash,” “conference” or “link” button found on your phone. The term used for conferencing calls may vary according to your telephone company’s features and procedures.
8. When the other party answers, the CA will not identify or explain Relay – the CA is present only to type what’s said by the other party.
9. Throughout the call, speak directly to the other party – there is no need for either of you to say “Go Ahead” or “GA” as Relay and the CA will be “invisible.”

Receiving Calls with VCO

It is best to establish a Customer Profile indicating you are a VCO user so the CA can connect your calls immediately. If you haven’t established a Customer Profile, you may answer incoming calls in one of two ways:

1. Upon answering, say “VCO PLEASE GA” and immediately connect your TTY or VCO device OR
2. Connect your TTY and type “VCO PLS GA.” If using a VCO device, you may simply press the “RLY MSG” button that sends a recorded VCO prompt.
3. The CA will then connect Voice Carry Over and type: “VCO ON GA.” Your call can then proceed as usual.
