Quintum Addressses VoIP Continuity in PBX Branches

Spencer D. Chin, TMCnet Web Editor

Quintum (News - Alert) Technologies has announced that the survivability function, first introduced in the Tenor AF and AX lines, is now available on the digital Tenor DX and BX VoIP MultiPath Switches.
Quintum addressed the need to assure business continuity in branch office locations in the event that connectivity to the main IP PBX (News - Alert) or IP Centrex is lost. Small to medium sized enterprises, larger enterprises with remote offices deploying VoIP in IP-PBX branch offices, and service providers deploying hosted IP-PBX services CPE and IP Centrex CPE, are now assured of survivability through the local PSTN for local access and E911 emergency services.
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. It will assure that basic, essential calling functions will continue even if connectivity to the central or hosted IP PBX is lost. And its unique endpoint discovery feature allows Tenor to be easily deployed without requiring configuration for SIP endpoints.
Tenor S has sophisticated call routing and programmable interfaces to integrate legacy telephony devices and PBXs into an IP telephony network. A single Tenor can integrate a legacy PBX, provide connectivity to the PSTN and provide survivability for SIP endpoints—easing migration from a user’s current network to IP telephony.
The new digital survivable Tenor S products supplement the original Tenor product line, which supports H.323 and SIP-based support of traditional PBX trunking, legacy equipment VoIP integration and VoIP-PSTN connectivity. Both the regular and the survivable analog Tenor AF and AX series products support legacy phones, fax machines and modem-based devices.
All Tenors offer anywhere anytime remote management, even if they are deployed behind NAT firewalls with the external Remote Management Session Server. The RMSS allows easy and secure access to remote Tenors diagnostics, upgrade and configuration, even behind the enterprise NAT/firewall.
“The new survivable versions of our Tenor BX and DX series now afford our larger enterprise customers the ability to connect their traditional PBX, IP PBXs and IP phones, IVR and ACD systems and other key elements of their communications network and provide for survivability in remote locations,” said Charles Rutledge, vice president of marketing for Quintum. “Likewise, service providers can now deploy hosted IP PBX and IP Centrex solutions using Tenor to integrate legacy telephony equipment while assuring survivability for their customers.”
List prices are $990 for the Survivable Tenor BX and $3,300 for the Survivable Tenor DX.
