I have an older DR% software 8x24. They want to add several phones to ring at night. I poked around in programming for awhile and was unable to find anything. So I grabbed manual. It says under heading 6. Service modes I should see
Control Telephones
Name
Setting
Trunk answer
Extra-dail
Ringing telephones
aux ringer

When I scroll through the list, it jumps to
7. Passwords right after extra dial. Does this mean I can't add ringing phones?
