Welcome to the latest edition of

This month's
TENOR HIGH NOTES

New Products:

Tenor Call Relay

- At the Internet Telephony show in San Diego we debuted our
Network Portal. The Tenor Call Relay provides a single VoIP portal between IP networks allowing for end-to-end
VoIP communications across multiple IP networks. All calls are switched through multiple IP networks with just
one single compression and decompression of the voice. It allows VoIP endpoints behind a NAT and firewall to
communicate with external VoIP networks.

Tenor GateKeeper

announced at VON in Atlanta.
administration for all H.323 VoIP endpoints in a network, including gateways, IP phones and PC clients. It
dynamically self-configures the VoIP routing database, and will support static routing to provide connectivity to
endpoints not part of your VoIP network. It provides load balancing among multiple gateways and authentication
and authorization of all calls in your VoIP network. Quintum's Tenor Gatekeeper "base" unit sells for $1000. 100-
call increments are available for $2500 and 20-call increments are available for $600. Competitors sell 20-call
increments for $2000 and more.

New Functionality:

NATAccess™
is unique technology in the Tenor VoIP MultiPath Switches that allows VoIP implementers to
deploy the Tenor VoIP MultiPath Switch behind NATs and NAT-enabled firewalls. Quintum's innovative
NATAccess performs network address translation within packet payloads during the call set-up process. By
providing the outside party's router with the appropriate public IP addresses for internal users, NATAccess allows
authorized streaming VoIP traffic – and only authorized traffic – to pass through the firewall.

IVR/RADIUS Interface

pre-paid, post-paid, calling card and other payment plans for VoIP using any standards-compliant call accounting
system. Tenor's integrated support for IVR and RADIUS (Remote Authentication Dial-In User Service)
applications gives service providers the flexibility to use either their existing and/or best-in-class third-party call
accounting/control systems as they roll out VoIP services.
