"Why use VoFR rather than VoIP?"
  • The answer is, of course, "It depends.
  • In a VoFR environment, all the voice-capable
    routers must be Frame Relay network edge devices,
    and must be directly connected to the Frame Relay
    service.
  • With VoIP, however, this is not the case because
    we can route voice traffic to the individual
    voice-capable devices just as easily as routing
    data.
  • The routing process doesnt change. Is one better
    than the other? It depends.
  • What are you hoping to accomplish the
    technology? How is your network laid out?

10
  • Frame Relay transports voice traffic over the
    same PVCs used for data traffic. This is the case
    unless separate PVCs have been purchased for both
    voice and data.
  • If separate PVCs are provisioned for both, they
    can be treated differently (i.e. traffic shaped
    and prioritized differently if desired).
  • Cisco's recommendation, however, is to purchase
    adequate bandwidth and keep voice and data on the
    same PVCs for simplified administration, as well
    as to allow the VoFR specifications (FRF.11 and
    FRF.12) to work together properly.

11
  • Telephones are attached to Foreign eXchange
    Station (FXS) ports of the VoFR-capable device.
    FXS ports are ports into which any type of
    station equipment (i.e., phone, fax, caller ID
    box, answering machine, etc.) can be plugged.
    When an attached phone goes off-hook, the device
    detects it and returns dial tone. A phone number
    is dialed, as in any other phone call. The VoFR
    device must then interpret the digits and forward
    them if necessary.
