Configuring Call Preferences
Call preferences help you manage the network bandwidth used for calls. For
example, you can specify the default and optional call settings for outgoing calls,
and limit the call speeds for incoming calls.
If you have just set up your network, use the screens described in this section to
specify your call settings. If your network has been set up for some time, but you
notice that your call quality is not optimal, you may want to change some of these
call preference settings to increase the quality of your calls.
To configure your call preferences:
1. Go to System > Admin Settings > Network > Call Preference.
2. Configure these settings:
3. If you have the ISDN option, select to go to the Network Dialing screen
and specify the dialing order preference between IP and ISDN.
