Acme Packet Nets Four New Customers in Canada.

Broad-Connect Telecom, Call Genie, MTO Telecom and Protus showcase broad range of Acme Packet Net-Net session border control applications

BURLINGTON, Mass. -- Acme Packet[R] (NASDAQ: APKT), the leader in session border control solutions, today announced four new customers across Canada that are leveraging Acme Packet's Net-Net[R] session border controllers (SBCs) for the delivery of trusted, first-class IP interactive communications. Broad-Connect Telecom, Call Genie, MTO Telecom and Protus have deployed Net-Net SBCs to provide security and SIP session control for delivery of a broad range of VoIP services. Acme Packet SBCs are now deployed in 20 service provider and enterprise networks in Canada.

Acme Packet's new Canadian customers are using the Net-Net SBCs at both the access and interconnect borders, protecting their networks with the advanced security afforded by Acme Packet's Net-SAFE[R] architecture for denial of service (DoS/DDoS) attack protection, network topology hiding and access control lists. In support of wireline access services, Acme Packet's hosted NAT traversal feature maximizes service reach by enabling calls to traverse firewalls without disruption at customer sites. Three of the four customers--Call Genie, MTO Telecom and Protus-- also use the Acme Packet SBC for SIP session routing, leveraging Acme Packet's integrated routing database to map inbound calls to specific peers or application servers, simplifying their networks and minimizing capital expenditures.

Acme Packet's new service provider customers are located throughout Canada and include IP telephony service providers (ITSPs), Internet service providers (ISPs) and application service providers (ASPs):

* Broad-Connect Telecom, a SIP termination provider and ITSP in Toronto, uses Acme Packet's Net-Net Session Director (SD) to support its hosted VoIP and SIP trunking services for small and medium businesses, as well as SIP interconnects with peering partners.

* Call Genie Inc., a mobile local search and advertising company with offices in Toronto, Calgary, San Francisco and London, uses Acme Packet to support its voice-enabled search solution. Call Genie delivers the voice-activated directory lookups to its major North American service provider customers across connections secured and routed by Acme Packet's Net-Net SBCs.

* MTO Telecom, an ISP in Montreal, uses Acme Packet SBCs to interconnect with long distance and PSTN termination partners in support of its hosted VoIP services. Acme Packet's Local Route Table (LRT) allows MTO Telecom to associate SIP endpoints with directory numbers for the purpose of call termination.

* Protus, a software as a service (SaaS) provider in Ottawa, has deployed a pair of Net-Net SDs in a high-availability configuration in two different locations for geographic redundancy to support its hosted Internet fax service MyFax[R] and my1voice[TM], a virtual PBX phone service for small and medium businesses.

"During our testing, Acme Packet's solutions proved to have the richest functionality in terms of architectural flexibility, interoperability, session control and feature depth," said Dominic Ogbonna, director of technology at Broad-Connect Telecom. "The Net-Net SBCs have enabled us to cost-effectively maximize the reach and quality of our services, giving us the competitive edge we need to continue to win customers and grow our business."

"As a leading provider of high quality SaaS communications tools for businesses, we need robust security and quality controls for our network," added Simon Nehme, CTO, Protus. "Acme Packet's session border controllers delivered those requirements so that Protus can provide a superior user experience."

"Service providers of all types and sizes need the tools and capabilities to differentiate their offerings while keeping costs down," explained Seamus Hourihan, vice president of marketing and product management at Acme Packet. "Acme Packet's Net-Net SBCs are flexible, scalable solutions that enable the trusted delivery of a wide variety of value-added services to help these providers create a market for their services."
