Quintum Tenor AX VoIP Gateway Router QoS
For up to 24 simultaneous VoIP calls

Tenor AX For up to 24 simultaneous VoIP calls


The Quintum® Tenor® AX Series gives larger businesses with analog voice infrastructures an easy, cost-effective way to
capitalize on the power of Voice over IP (VoIP). The Tenor integrates a gateway, a gatekeeper, and intelligent call routing,
and supports QoS all in one solution. With its MultiPath architecture, the Tenor connects to the data network through a
10/100 Ethernet interface, the voice network through either a PBX or phone, and the public switched telephone

A more intelligent way to implement VoIP

The Tenor AX Series offers:
• SelectNet™ provides superior voice quality
• Tranparent MultiPath Call Routing
• Integrated H.323 gateway and gatekeeper
• SIP User Agent
• IVR/RADIUS AAA compliant
• Stackable architecture
• Answer and Disconnect Supervision
• 8, 16, or 24 Analog line and trunk interfaces
• Up to 24 simultaneous VoIP calls
• Available in MultiPath or Gateway configurations

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 mid-call to the voice network whenever conditions demand.

More intelligence means greater flexibility.
With its MultiPath Call Routing, the Tenor can intelligently route calls between the PBX, the PSTN, and the IP network to achieve the best combination of cost and quality. The Tenor can also route calls over IP to reduce costs, and then transparently "hop off" to the PSTN, to reach off-net locations. No other VoIP solution can match this flexibility.

More intelligence means easier installation.
With its MultiPath architecture, the Tenor is the only VoIP solution that can be installed without upgrades to the existing voice or data networks. Tenor connects to the data network through a 10/100 Ethernet interface, and to the enterprise and public voice network through a T1, E1, or PRI interface.

More intelligence means greater reliability.
The Tenor is designed to pass calls through to the existing voice network in the event of system malfunction – even a total power failure.

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
