I recently had a Nortel BCM 50 installed by Advanced Communications Solutions in VA. 5 or 6 phones (model 7316E) out of 12 have failed totally or had a display failure. Total time since installation, about 2 months.

The expansion model failed. My business needs good reliable phones. How do I get Nortel or the dealer (We are at an impasse...) to take the system back?

Also, how would one ID gray market phones?
