Hi all, my customer has a magix r3 with two 016 ETR modules and 6 800 modules as well as merlin messaging. They use partner 18d phones with 3-4 lines programmed on each phone. A few days ago and today twice during calls all phones turn off. No lights, no display- Dead. The customer says they stay off for 30 secs to a minute. They recently installed a new UPS for the system. I've suggested replacing the 016 modules but was wondering if I should check something else. The error logs say- Transient error- power up cold start- code 0016.
Thanks.
