We have a client with a MICS 7.0 and a CP150 with 64MB.. Since last year we have lost the programming on the CP150 3 times. The client will just notice that the voicemail is not answering and we get the call and it is defaulted back to 20MB and nothing in it. We have to initalize, reload licenses and do all recordings again. I am going to get a back up today but what can be causing this issue. The system is on a surge protector and small UPS we have a new UPS going in soon. Telephone system is fine every time.Is it power spike? Bad software ?
