What is 1-line VCO and how is it different from 2-line VCO?

One-line VCO is the latest and most revolutionary form of VRS technology available to Deaf and hard of hearing individuals who prefer to use their voice in VRS calls. The older and more outdated form called 2 line VCO consisted of what’s called a ‘callback number,’ which refers to a landline phone, cell phone or PDA from which the Deaf or hard of hearing VRS user can talk to the hearing person.

With the new Z videophone family, a ‘callback number’ is no longer required! Its result is an effortless, convenient and efficient phone call where you can talk DIRECTLY into the videophone. All of the Z videophones have top-quality audio microphones and are compatible with hearing aids and cochlear implants. In addition, should you desire a headset eliminating any possible background noise, we have a list of suggested equipment available for purchase at various retail stores.
