We will be installing a Modular ICS with 7.1 with (1) PRI and DID's. We want their main DID number to be answered by the Auto Attendant. I seem to remember in the past we could only stack up 2 inbound DID calls at once to the same DID number. The 3rd and further calls would either go to the main console or busy. This customer will be using this (1) DID number as their main number. At any point in the day, this customer could stack up several calls at once. There is no receptionist at this site, thus the AA. Thank you for your response.
