Voicemail to Email

I had lost power to my server last week. and Since that time, when someone leaves a message, it does not email it to me like before.
The person that orginally set this up for can not be reached. SO I am kinda stuck. It has happen before, and he had signed in and fixed it up. I just don’t know what was done. If it was on FreePBX end, or DYNdns side…

Can someone point me in the right direction…
