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 gen-
erated 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.
This procedure describes how to enable silence compression.
