Description
This read-only window displays the combination of
compression algorithms that are available in the DSP load
selected in the DSP Load drop down list.
The compression algorithm (G.711, G.726, or G.729A)
used on calls to or from the Remote Gateway 9100 Series
unit stations is dictated by the compression setting
configured for the remote port that the call is processed
over.
