Hello everybody. I am having a pretty strange issue with an IP Office at a customer's office. They have 4 analog lines setup in incoming call route "0" which is programmed to ring a group of phones. Today, for the third time now, the incoming call route is all of the sudden going straight to their voicemail. I logged in through the Avaya Manager and sure enough, incoming call route 0 is set to go to voicemail. The other times this has happened I have changed it back to the hunt group it's supposed to be ringing, but for some reason it ends up going back to voicemail. The first time it did this was after 3 or 4 days, and this time it was after about a week and a half, and everytime it had been changed when the staff comes in first thing in the morning. I am changing it back again right now, but has anyone seen this or have any idea why this might be happening? The system has been installed for about a year and a half and never had any problems until a couple of weeks ago. The software version is 8.1 Essential. As always, I greatly appreciate any and all help you guys can give me. Thanks!
