Los Angeles (September 16, 2008) - Grandstream Networks, a globally recognized manufacturer of high quality and affordable IP PBXs, SIP trunking gateways and IP voice and video solutions for the worldwide VoIP SMB market, is pleased to announce full interoperability with Quantum Voice's VoIP network. The two companies have also teamed efforts to create a one button provisioning protocol to easily provision edge CPE devices onto Quantum Voice's targeted VoIP network. By working together, Grandstream and Quantum Voice have collaborated to meet the needs of the SMB looking for ease-of-use, high quality and affordability from their IP-PBX and network. Grandstream's powerful hardware solution combined with Quantum Voice's robust network now offer the small to medium sized business world wide a competitive, affordable and complete solution.

Grandstream and Quantum Voice have collaborated to provide the SMB with an overdue solution that eliminates pain points that have hindered VoIP proliferation. Such points include unpredictable capital and operational costs, complicated set-up and administration, and overall unreliability from the IP-PBX and network. Grandstream's hardware and Quantum Voice's network alone tackle the problems of unpredictable capital costs and unreliability. Together, Quantum Voice and Grandstream rid the SMB of the complicated set-up and administration involved in IP-PBX installation and deployment with one-button provisioning by tying the network and hardware together for seamless integration. With one-button provisioning Grandstream's GXE502x and Quantum Voice's SIP Trunks are tightly coupled to allow near out-of-box provisioning for the SMB, thus eliminating the taxing administration and set-up time often experienced in the field. Grandstream's network elements will provide the end-user with an easyto- use interface with a single "1-button" request for Quantum Voice's VoIP services. Through this one button "push" the end-user will be able to instantly provision a complex network element onto Quantum Voice's targeted network. In addition to eliminating the time and resources, this technology eliminates human error, connectivity issues and ensures data integrity and security.

"From our inception, we drew a line in the sand by avoiding solutions that that failed to offer robust feature sets or did not reasonably adhere to industry standards. This often meant that we were at odds with manufacturers," said Ben Carrasco, CEO at Quantumvoice. "However, something quite unexpected happened during our lab tests of the GXE502x, in the 20 or so minutes that it took us to provision and begin using it, we suddenly realized that Grandstream shares the same no-nonsense philosophy and thought we would celebrate it by offering a promotion to all GXE502x customers that will allow them to take full advantage of its capabilities!"

"We are very pleased to announce our partnership with Quantum Voice. Quantum Voice's strong telecommunications presence combined with the advanced capabilities of our GXE502x IPPBX is a powerful turnkey solution for the SMB," adds David Li, CEO of Grandstream Networks. "We look forward to continue working closely with Quantum Voice to ensure an unprecedented user experience and value proposition for SMB."

Quantum Voice will offer 500 free minutes on their network for customers who purchase the GXE502x coupled with their services.
