Thanks Ed,

I'm going to reprogram the buttons and keep an eye on it.
I'll explain to the customer it is very unusual. She may have tried moving her desk phone to a nearby conference table where I have a basic VU-9208 phone.

To refresh my memory, to reprogram the flex buttons for DSS/BLF, is it merely:
1. Press [Trans/PGM]
2. Press desired flex button.
3. Press [Trans/PGM] button
4. Dial [Station #]
5. Press [Hold/Save]

Is there a Program Code needed from Appendix A?
