Write a summary description of voice over frame relay (VoFR).
What will be an ideal response?
Frame relay includes an option, called voice over frame relay (VoFR), to transmit voice signals over the network to reduce long-distance telephone costs between sites. Voice transmissions are accomplished by using one of two techniques: voice compression and silence suppression. Both techniques are used to increase the available bandwidth for data and voice.
