Voice Compression

Get more out of Asterisk by offloading codec conversions to Digium's TC voice compression cards.  Software transcoding takes up host CPU cycles and can limit the capacity of your server.  TC cards are dedicated hardware transcoders; they drastically reducing the bandwidth consumed by each call without ever touching your host CPU. Our voice compression cards are capable of compressing/decompressing 120 channels of G.729 or 92 channels of G.723.1.
