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.
