I have a customer who wants to shut off the automated attendant and just use the voicemail. The attendant (21) will not have voicemail and will just ring until the phone is answered. I removed her mailbox but now after the 5th ring I get a "Sorry that wasn't a valid phone number or group list number" message no matter what line I dial in on. I set up 21 to forward to 22 after 3 rings as a test and it did forward but after a total of 5 rings I got the same Sorry message. Only station 21 rings (I cleared ringing on 22-37) Any ideas?
