COMPARING VoFR AND VoIP PACKET TECHNOLOGIES

There are four main areas of material differences between VoIP and VoFR packet management technologies:
· Packet overhead
· WAN access-line carrying capacities and associated cost implications
· Packet prioritization
· Packet segmentation or fragmentation and its effect on data packet sizes

Each area of difference presents more of a challenge to the VoIP gateway approach than the VoFR approach, both because VoFR is more mature and because VoIP has a few inherent technological handicaps.
