For large building with over 100 units, Auto-Dialer systems may be a better fit than a wired telephone entry system because of the large number of phone lines that need to be intercepted. That advantage may compensate for many other features that clearly put them at a disadvantage in smaller apartment buildings.

Line rental fees incurred by the condominium with the use of an Auto-Dialer telephone entry system is one of them. These systems effectively require a dedicated line from the local phone company for their normal operation: when a guest calls a resident's unit, the system actually makes a phone call to the resident's line. In most areas, telephone companies treat these lines as business lines making the line phone bill disastrously more than residents's are willing to pay for.

Auto-Dialer telephone entry systems also require residents to order from the local phone company call waiting service for their lines. This is so they can be reached by a calling guest at the lobby while they are on a phone call. This is doomed to unhappily increase their phone bills if they did not desire such a service. At the same time, the call waiting service can become an impediment for internet use of the line: the call waiting tone will disconnect their computer modem from the internet while they are online. If they momentarily disable the service before they go online, then they will miss all possible guests's calls!

In addition, Auto-Dialer telephone entry systems are vulnerable to long distance call abuse as anyone gaining access to the line jack can easily make undesired and unauthorized call that are difficult to track in a condo environment.

Another major disadvantage of Auto-Dialer telephone entry systems is that they are subject to the numbering system of local telephone companies. Many such entry systems have become unusable today as a result of the increase in telephone numbers which in many areas passed from 7 digits to 10 digit (phone numbers have passed to include the area code). There is only so much memory space that can be cost-effectively accomodated in a system for residents's phone numbers. Even increasing this capacity to some more digits per apartment unit still leave these telephone entry systems at the mercy of future changes in the public telephone numbering system. This obviously all means loss of their investments by building owners.

Wired telephone entry systems are immune to most of these problems. The OmniCom Telephone Entry System is immune to all of them. For relatively small condominiums with less than 100 units, the choice is clear.
