Managing lines with BG Admin To manage the lines in your Department, click on the All Lines option on the left-hand sidebar. This menu shows all the lines within the department(s) of which you are an administrator. Business Groups with more than 10,000 lines Business Groups can support up to a maximum of 40,000 lines.  Any Business Group that has more than 10,000 lines will be configured slightly differently as follows. If you are a BG Admin in a Business Group that is configured to support more than 10,000 lines, you should note the following: All lines must be in a specific Department. You will see a warning if there are any lines that are in the root Department, and will be prompted to move them to a sub-Department. If you are an administrator of the root Department for this Business Group, you will not see a list of all lines but will be prompted to select a Department (which could be the root Department). If you are an administrator for the entire Business Group, you will see all lines within the Business Group.
