32.6 Enable Silence Compression
Silence compression detects the silent periods in a phone conversation and stops the sending of
media packets during these periods. Since conversations are essentially half duplex (people do not
talk simultaneously) this can reduce the bandwidth consumption of a voice over packet connection
considerably. Comfort noise is generated at the remote end of the silent direction to avoid the
impression that the connection is dead. Silence compression and comfort noise can only be enabled
together.
