[11.5.0]Voicemail issues

I recently installed Asterisk on my Synology. Incoming calls working flawless, they get rerouted to voicemail, but here the problems start:

  • I can hear my own unavailable-message, but after that vm-intro.gsm gets played. I don’t want that and I can’t find it in extensions.conf. Where can I disable vm-intro.gsm and vm-goodbye.gsm?

removing them is no issue, same with silencing them.
