We have another company coming into our building. We are going to share 1 Avaya Partner Phone Messaging System. We have a total of 7 lines with 3 of the lines in a different hunt group set up for the other company which I will call "b". We have 2 auto attendants, one for office "a" and one for "b". "B" will have three extensions with phones attached. How do I change the 0 time out option for the 3 extensions to route back to the auto attendant for "b". Currently, if I press 0 during the voice greeting for one of "b" extensions the call is being routed to an extension for office "a". We don't want the phones to be crossed between companies.
