Voicemail blackhole

I need some help as I can’t figure out why this is happening. I have a ring group set up that rings two extensions (7211 and 7213) and if no one answers send the call to the voicemail of extension 7211. All this works fine. Per log files it is leaving voicemail too. However once complete there is nothing in var/spool/asterisk/voicemail/default or /device for that extension and there is no voicemail per the phone. Any thoughts would be greatly appreciated. This is a new one for me. I used freepbx to set up the ring group and it worked before the ring group was set up.
