60 CHAPTER 1: INTRODUCTIONupgrade installed can create system performance issues. To ensureacceptable performance you should configure a system that has only thebase-memory to adhere to the following system configuration guidelines:■ Configure up to 5 devices for each ACD Group plus Hunt Group.■ Configure up to 75 Phantom Mailboxes for each ACD Group plusHunt Groupor500 Account Codes for each ACD Group plus Hunt Group. Forexample, on a V3001 system, to have 75 Groups and 250 devices, youcan have no more than 2500 Account Codes and 150 PhantomMailboxes.Here are some sample supported combinations of features for V3001Analog, V3001 BRI, V3000 Analog, and V3000 BRI systems that do nothave the optional memory upgrade:V3001R systems and V3001 Analog, V3001 BRI, V3000 Analog, andV3000 BRI systems that have the optional memory upgrade installed cansupport the licensed limits of 1500 devices, 150 Phantom Mailboxes, 48Hunt Groups and ACD Groups, and 5000 Account Codes. Note that youcan improve performance on a system that is subject to heavy callingloads by decreasing the number of ACD Groups and Hunt Groups.Licensed DeviceLimitsCertain devices and applications have limits that are governed by licenses.Device licensing is explained in detail in “Device Licenses Details” onpage 75.
