Click the Add button to add a codec profile. Click the

Name of the codec profile. You can modify the name,
and click Apply. The Default profile name cannot be
changed.
There are three options:
• G.711
• Prefer G.723.1, support G.729
• Prefer G.729, support G.723.1
G.711 provides toll quality digital voice encoding,
and G.723/G.729 use low rate audio encoding to
provide near toll quality performance under clean
channel conditions.
When silence suppression is enabled, and silence is
detected during a call, AltiWare stops sending
packets to the other side. This decreases the
bandwidth requirement, however the voice quality
may be degraded slightly. These are system-wide
settings.
