Ok, this is a new one for me.

We have an Axxess 64 with EVMC in our Boston office. Version 5.351 It lost any programming associated with call routing application and STARs. They were all there, but within them all defaulted. No recordings within the day/night greeting, except the default #1 voicemail greeting, and the digit translations were all back to "invalid".

Mailboxes and all station programming is still intact. I reprogrammed what was missing, and all is working again, but guessing it's going to happen again. The error log shows nothing.

What might have caused this? Is there a battery that might need replaced within the EVMC?

Thanks.
