Multipoint, NI-1, or Nortel DMS-100, select
SPIDs provided by your service provider.
After you enter the SPIDs, the system verifies them. If the system is unable
to verify the SPIDs, make sure the system is connected and that the ISDN
numbers you entered are correct.
If you do not have the SPIDs from your service provider, you can click
Start to Auto-Detect SPIDs.
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.

1. Go to System > Admin Settings > Network > Call Preference.
