Have a customer that has 10 locations. Each location has an IPO running some flavor of R9 software. Theses sites are all networked together via SCN. The main site serves as the host site for VM Pro.

Voicemail for everyone at every site works well, except for one remote location. At this location, they have a group mailbox that is assigned to the main hunt group. If a VM gets left in this group mailbox, all the member extensions get a notification and if you press the VM key, visual voicemail shows messages in this group mailbox. However, they cannot play the message. When you scroll to that mailbox and press Ok, it simply does nothing. Personal mailboxes on individual extensions are fine. If they reboot the IPO at this remote location, they can access and play messages out of this group mailbox one time. After that, it doesn't work again.

At the main site (where VM Pro is located), I added one of the extensions to the group at the remote location that is having issues. I can play, delete, save messages without any problem.

I deleted the entire mailbox and re-created, and no help.

Any ideas what could be going on here?
