Since several weeks, the voicemail messages are not forwarded to e-mail anymore. The e-mail server is working indeed. The voice messages can still be listened to by dialing *97 (if the extension is not configured to delete them after forwarding).
We are using the Premium account "opf" with ~10 extensions on www3 and all extensions voicemails are experiencing the same problem. I have tried to create a new extension and to change the forwarding e-mail address but no e-mail is received as well.
I have a customer with another Premium account on www1 who doesn't have the problem, so maybe it is specific to www3?
