Aspect Leverages Acme Packet Enterprise SBCs with Verizon IP Trunking and Microsoft® Lync™

Acme Packet® (NASDAQ: APKT), the leader in session border control solutions, today announced that Chelmsford, Mass.-based Aspect®, a global provider of unified communications and collaboration (UC&C) services and software, has deployed Acme Packet’s Net-Net® Session Director (SD) enterprise session border controller (E-SBC) to enable the SIP trunking connection between Aspect’s Microsoft Lync 2010 UC&C environment and Verizon’s IP Trunking service. The Net-Net SD was recently qualified under Microsoft’s Unified Communications Open Interoperability Program (UC OIP) with Microsoft’s Lync 2010 Server and Verizon’s IP Trunking service.

Aspect helps organizations apply Microsoft® unified communications and collaboration to enable its customers to achieve optimal results through enhanced business processes across the enterprise and in the contact center. Aspect also leverages Microsoft Lync globally for all of its own voice and voicemail services, audio and web conferencing, instant messaging (IM) and presence. Aspect was among the first of Verizon’s and Microsoft’s mutual customers to benefit from effectively employing Microsoft unified communications applications across Verizon’s IP Trunking solution for more cost-effective and high-performance application delivery.

Verizon IP Trunking features the company’s Burstable Enterprise Shared Trunk (BEST) capability, which enables customers to use idle trunk capacity at one location to accommodate an increase in traffic at another. This reduces the total number of voice communications trunks required to link the company's locations, in addition to offering cost savings.

Acme Packet’s E-SBC connects Aspect’s global employees to users beyond its Microsoft Lync domain via the Verizon IP Trunking service. In this role, the E-SBC routes SIP sessions, applies signaling and media controls to incoming and outbound SIP session traffic, and establishes demarcation between the Aspect and Verizon networks. By implementing Verizon’s award-winning VoIP solutions, including the company’s IP Trunking service, Aspect has been able to achieve greater control over its call routing and management, as well as significant savings through the consolidation of traditional local access lines and trunks.

"As part of our deployment of Microsoft Lync, we needed to ensure that we could communicate reliably with the outside world, and Acme Packet plays a key role in making that happen,” said Jamie Ryan, Aspect’s Senior Vice President, Information Technology and Chief Information Officer. "The fact that Acme Packet’s E-SBC was UCOIP-qualified made it an easy choice for deployment with our Verizon IP Trunking service.”

"Enterprises making the transition from TDM to IP want the security of knowing that their communications environments are highly reliable and will interoperate seamlessly with SIP trunking services,” said Dino Di Palma, Acme Packet’s senior vice president of worldwide sales and business development. "Our E-SBCs are a great fit for enterprises like Aspect, who require a fully-qualified system to ensure the availability of its UC infrastructure, services and applications.”
