An error has occurred on voicemail

Hi Guys,

I’ve got a problem with voicemail. Everytime it will direct to a voicemail, “an error has occured” is played.

I’ve check voicemail.conf, there are no listed extensions in there. I already tried amportal chown (result; permissions ok) and recheck if the permission for voicemail.conf is 664, permission for var/spool/asterisk/voicemail is 775.

I already tried editing voicemail.conf, adding each extensions. It will solve the issue but when I go to GUI and edit something and press submit, the problem will return again. Seems like something is overwriting voicemail.conf, I guess.

Is it a bug or something?

Has anyone solve this issue? What exactly did you do?
