This attribute specifies the expected savings (percent reduction) in
required bandwidth if silence suppression is used. If silence
suppression is used, the bandwidth required for the connection will
be lower than if silence suppression is not used. However, the
routing system will not be aware of the unused bandwidth unless
that bandwidth is specified by this attribute.
If the value specified for the expected savings is too low, then some
bandwidth made available by the use of silence suppression will be
wasted. If the value specified for the expected savings is too high,
then some connections may fail to set up because the routing system
will over-calculate the amount of bandwidth available.
The effectiveness of silence suppression can be influenced by
language related speech patterns.
