Quintum® Debuts New Survivable "S" Versions of its Tenor® VoIP Switches and Gateways That Assure IP Telephony Network Survivability

  • The new Survivable Tenor S provides a complete VoIP branch office solution assuring business continuity in the event of IP network failure

Quintum Technologies announced that they have debuted a new enhanced Survivable version of its Tenor VoIP MultiPath Switch that has been compatibility tested by Avaya.

EATONTOWN, N.J. – Quintum Technologies, a leading innovator in VoIP technologies, announced today that they have debuted a new enhanced Survivable version of its Tenor VoIP MultiPath Switch that will provide local support of a branch office IP telephony network when IP connectivity with the voice server at the main location is lost.  Quintum addressed the needs of enterprises that are deploying VoIP in IP-PBX branch offices, or service providers that are deploying hosted IP-PBX services CPE and IP Centrex CPE and need to assure the business continuity in remote locations. The new Survivable Tenor S is a complete solution that will be the only device needed in the branch office to support all legacy equipment, local PSTN connectivity and survivability of the local IP telephony network. 


The new Survivable Tenor S contains a local SIP proxy that provides survivability for local SIP endpoints and intelligent call routing to keep any SIP-based VoIP network up and running if connectivity with the main proxy server is lost. Without the server connectivity, IP phones would not be able to operate. In event of an IP failure, the new Survivable Tenor S keeps the local IP telephony phone network operational, regardless of what happens on the wide area network. Combined with their unique PSTN failover capabilities, this feature makes Tenor switches the most survivable solution on the market.


As announced separately today, the new Tenor solution has been compatibility tested by Avaya, a leading global provider of business communications applications, systems and services, for interoperability with the company's IP telephony solutions. Quintum is a member of the Avaya DeveloperConnection program, an initiative to develop, market and sell innovative third-party products that interoperate with Avaya technology and extend the value of a company's investment in its network.


"Quintum's new survivable Tenor has been tested and approved as interoperable with Avaya's industry-leading Communication Manager 3.1 IP telephony software," said Eric Rossman, vice president, developer relations and technical alliances, Avaya. "As a result, Avaya customers now can confidently add Tenor to their existing network operations."


"All of 3Com's VoIP applications including telephony, messaging and conferencing are built natively on SIP and open standards," said Anna Dorcey, Vice President Technology Partner Program at 3Com. "3Com prides itself on an open architecture enabling rich applications and multi-vendor devices to interoperate. Customers now have the opportunity to deploy Quintum's Tenor Switches and Gateways in multi-site networks. As a member of our Voice Solution Provider Program, Quintum's Tenor has been compliance tested as interoperable with the VCX environment, offering a complementary solution that provides flexibility for branch office applications."


The new Survivable Tenor S supplements the original Tenor, which supports H.323 and SIP-based support of traditional PBX trunking, legacy equipment VoIP integration and VoIP-PSTN connectivity. The original Tenor is used in a wide variety of applications, including inter-office trunking, IP-PBX legacy integration, service provider VoIP trunking, call centers and termination, among others.


Both versions of Tenor are built on Quintum's unique MultiPath architecture and offer intelligent MultiPath call routing between circuit switching and VoIP, including network "hop-on" and "hop-off," and PSTN connectivity to 911 emergency services. Both offer easy, transparent installation in existing network infrastructure and assured voice QoS to monitor IP traffic and switch calls to an alternate network in the event that jitter, packet loss or latency will jeopardize call quality. 


In addition, all Tenors offer easy remote management, even if they are deployed behind NAT firewalls. With the external Remote Management Session Server, announced earlier this year, remote Tenors can be easily diagnosed, upgraded and configured, even behind the enterprise NAT/firewall without someone being on site. 


"The original Tenor was designed to provide an easy to deploy VoIP solution at the edge of the enterprise network," said Chuck Rutledge, Vice President of Marketing for Quintum. "The new Survivable Tenor S brings the same ease of deployment to the remote office with the added benefit of providing survivability of the remote IP telephony network, thus assuring that business processes can continue unimpeded."

The new Survivable Tenor S is currently available in both the Tenor AF and AX series product lines. Starting list price is $365.00.
