Dual Line VCO

Dual line Voice Carry Over (VCO), which is sometimes called "two-line Voice Carry Over", is a special way of using Relay) that allows someone with two phone lines to not only see the text that the relay operator types, but to also hear what the other party has said.

To access, you need to give the relay operator the second number to use, and the operator will dial you back on the second line and send the sound over one line and the text over the other line.

You can also make use IP-Relay to make a VCO call, and you don't need two phone lines to do it, if your computer uses a high-speed modem (DSL or Cable) which doesn't tie up your normal phone line.
