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
