I have a customer who has a definity release 6 and is having problems with I believe to be corrupt software or bad processors they would like to upgrade system to newer release but the Business partner I deal with says they have to go to the s platform. This cust is going to Voip system in a few years (cisco). The cust has a console that locks up the loop keys a and b about every 2 weeks and they reset the system to clear I have replaced everything but the processors wire,console,and circuit packs
