A user cannot dial from a 2500-type telephone. The condition may exist on
more than one telephone and may be intermittent. The telephone may
occasionally experience a "no dial tone" condition. Calls from other types of
sets are not affected. Look up all system messages in the Option 11C
Compact software guide and follow the instructions given. If the fault does
not clear, use this procedure.
Constantly observe and look up system messages as you perform this
procedure.
