• Integrated VoIP and Circuit Switching: Intelligently switches calls between circuits (DS0s) and IP, between multiple circuits, and between IP endpoints.
• Enhanced Interactive Voice Response (IVR): Supports multiple user selectable languages and prompts.
• Advanced Call Routing Support: Quintum's external Tenor Advanced VoIP Call Routing Server* provides scalable, centralized network routing control and administration for larger networks. Provides enhanced networkwide routing flexibility including QoS routing, least cost routing, source based routing, and extensive network routing statistics/report generation.
• Network Management Support: Quintum’s external VoIP Network Manager* helps lower maintenance costs through centralized provisioning, alarm monitoring, CDR collecting and real time call monitoring.
• MultiPath Architecture: Allows easy installation at the customer premise.

Patented SelectNet™ Technology assures high quality voice.
The Tenor employs its patented SelectNet™ Technology to monitor calls for jitter, packet loss, and latency, and can transparently switch customers' calls to the PSTN whenever conditions demand. This intelligent switching allows you to achieve the Quality of Service targets that customers demand, at costs that traditional phone companies simply cannot match.

More intelligence means less network congestion.
With its PacketSaver™ Technology, the Tenor reduces bandwidth consumption up to 57%, by combining voice packets from several calls into a single packet to minimize bandwidth requirements.

NATAccess™ intelligence means greater security.
The Tenor VoIP MultiPath Switch also features a unique technology that allows it to operate behind NAT-enabled firewalls. The innovative NATAccess™ solution overcomes the problem of NAT firewalls not correctly translating internal IP addresses into public addresses when a VoIP call is established with an outside party.
