We have a very peculiar issue right now. We deployed a new 3CX install and set up one extension as the Voicemail for all routes going to voicemail. For testing, I set a DID directly to the voicemail of the extension. When I call, it plays the standard instructions and a beep, once I press # it says "Thank you and goodbye". No voicemail is saved.
When I call the voicemail internally via another phone, after pressing # it offers options like replay, delete and save. It works flawlessly in that case. I have not been able to figure out what is causing this issue and how to fix it. Does anyone have a clue what might be going wrong here?
 
I have changed MSADDRFC2833FORINBANDDTMF to 0 for the time being as our service provider sees no way to change things on their end. They have promised to keep investigating, but as of right now this (UNSUPPORTED) setting is the only way to fix this problem for us.
