Voice over Frame Relay is the encapuslation of voice into Frame Relay packets, therefore it is constrained only to Frame environments. VoIP is the encapsulation of voice into IP packets and is therefore not limited to Layer 2 stuff. I would add a third option which is IP Telephony, or the Cisco IP phones.
Tell us more about your requirements and what problem you are trying to solve as each has good things and bad things associated with it.
You can do VoIP without using IP phones. Hardware-wise, the setup would be the same as VoFR, except, as Rick said, the RTP audio stream would be in IP packets instead of FR frames.
A voice gateway at each site with an FXS port plugged into an analog phone with VoIP between them will work great.
If bandwidth is tight, then you will get some small savings with VoFR.
Sounds like either VoFR or VoIP will solve your problem. Keep in mind most new development is focused on VoIP vs. VoFR, so VoIP will provide you a more robust solution should you need expand down the line.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
