I’m running *@Home and have a few problems… in my sip_additional the mailbox is set to (exten)@device which does not work for the MWI on the grandstreams. When I take the “@device” out it works. Also, i’m trying to extend the ringtimer and I edit this in extensions_additional. Everything seems to work, but then it mysteriously changes itself back. I believe it occurs during a reboot, but I’m not positive.
I’ve tried manually editing these files and also tried editing them from AMP (config editor)… I seem to be having the same issue.
