Sangoma Transcoding Solution
Purpose of Document • Depending on the Sangoma Hardware Transcoding SKU the solution can
support between 30 and 4000 simultaneous G.729 sessions
• Hardware transcoding off loads CPU cycles from the host CPU and does not
require software G.729 licenses
• Hardware transcoding reduces transcoding delay
• High Compression CODEC’s allow more concurrent calls through Internet
connections with modest bandwidth.
• Voice Transcoding can reduce costs where bandwidth is expensive and VoIP is
desired to further reduce costs and increase mobility
