Auto Provisioning interface allows the Tenor solution to be deployed worldwide, and configured automatically by acquiring the configuration information from a central server, upon installation. The same auto-provisioning capability allows the Tenor to be configured from a VoIP application, thus supporting a single user interface between the VoIP application and the Tenor configuration.

Unified Communications Proxy (UCP) provides 'Any to Any' connectivity: SIP-SIP, TDM-TDM and SIP-TDM, for easy integration with any network.

NATAccess™ to allow Tenor to operate behind NAT firewalls to translate internal IP addresses into public addresses when a VoIP call is established with an outside party.
