The Audio Quality Preference screen allows you to choose an audio protocol.
G.722 audio delivers higher quality audio, but uses 48kbps of the video
bandwidth. G.728 delivers telephone quality audio and uses only 16kbps of the
video bandwidth. To set the audio protocol, use the + and - buttons on your
remote to move the slider. Changing the audio bars has no effect during a call.
Auto-Detect SPIDs
This screen appears only if you selected United States or Canada as your
country on the country screen. Highlight the Start icon and press the SELECT
button on the remote. This initiates a process for automatically detecting the
SPID (Service Profile Identifier) numbers associated with your ISDN line. This
process can take as long as 10 minutes, but will usually require three minutes or
less.
