r/avaya

Interested in how it is working for everyone.

I have a friend who runs an office that utilizes an old AVAYA phone system, specifically utilizing a AVS 509 processor running R8.0 and the mail VS r4.0. Some old messages are garbled and some messages are fine. Indicates to me that there is partial failure of the storage system. Is there any information on the replacement of the storage system (is it a spinning HHD or is it flash storage, is it serviceable?) or would I need to hop on ebay for a used mail VS.
