I need to setup custom voicemail welcome prompt for all sip accounts in one of my contexts,
I know that i can do this by creating a proper audio file inside /var/spool/asterisk/voicemail//
Problem is that i have more than 2000 accounts inside my DB (im using realtime users). I could create a copy of vm_intro in each of those folders, but it would be a total waste of available disk space.
Is there any way to set custom default voicemail prompt for all sip accounts inside context?
