I have an old SVMi-4e on an OS100 that has not given me any problems until now. A mailbox kept randomly changing the message notify telephone number to a weird series of numbers. I figured user error, and changed it back, only to find it happening again. So I swapped ports for the extension, and made a new mailbox. Problem is - I cannot get it to save the mailbox greeting. I record it, play it, press pound - and nothing. Not the keyset - I've tried it on several sets. Any suggestions?

Yes, I am retired - so why am I still working on phones?
