A growing number of vendors are now delivering VoFR solutions that target the requirements of mission-critical branch networks.
Today, VoFR standards use a number of VoFR compression techniques that range from 8 to 32 Kbps per voice channel.
Silence Suppression: Almost all of the DSPs used in today's VoFR implementations can detect and weed out silence patterns, reducing bandwidth requirements.
To minimize the 'clipping' effect caused by frame loss, some of the more advanced VoFR FRADs employ a lost speech interpolation technique that blends speech samples that precede and follow the lost frame(s) to mask the lost speech elements.
As with data, you can build a VoFR network without management.
For many applications, compelling economics fuel the migration to VoFR, with return on investments of less than six months being commonplace.
