AT&T SB67030 Administrator's Manual page 232

Symptom
The screen displays Synch
Failed.
Direct Dial no longer works.
Troubleshooting
Synapse Administrator's Guide
Probable Cause
The Deskset synch failed
when trying to connect to
the system.
You updated your Extension
Prefix, and that digit was
already being used as an
Auto Attendant menu option.
Corrective Action
Reset the Deskset. Insert a pen or paper clip into the reset
hole and press for more than five seconds.
If you assign Direct Inward Dial numbers with the first digit
of any extension that overlaps an Auto Attendant menu
numeric key value, callers will be unable to dial those
extensions. Instead, they will be connected to that Auto
Attendant menu action. Select a different DID number.
