The Ovation Series is a No Phone Bill unit that connects directly into each residence's telephone line and uses those lines to provide communication between the visitor entry and the tenant, resulting in no monthly or per-call charges. In addition, since the Ovation system generates its own line and ring voltage, the tenant is not required to have phone service for guests to contact them using this system.For extra security in high-risk areas, an optional lobby panel controller was developed to function with the ''VP'' (vandal-resistant lobby panel) and replaces the standard phone in the lobby. This ''VP'' lobby panel is specifically designed to repel harsh vandalism attempts with a faceplate that is made from rugged 316 stainless steel, 8-gauge thick, and can be secured to the backbox by heavy-duty security screws.
