system will try first when dialing a site (which can be reached
via IP and ISDN) from the Address Book. The choice can be

It is automatically reset to Manual if the setting matches that of
the Secondary Call Type Choice. If both ISDN and
LAN/Intranet are enabled, ISDN is the default.

system will use the secondary call type to automatically attempt
to reconnect.
