TalkTalk Business is one of the fastest growing B2B telecom providers in the UK. Supporting the communication needs of Britain’s businesses for over 20 years, TalkTalk Business’ Next Generation Network has grown to support thousands of UK businesses, and over 650 resellers – from voice and data specialists to systems integrators and carriers delivering complex IT solutions.

In September 2015, TalkTalk Business unveiled a new SIP trunk offering following the acquisition of tIPicall, a UK-based SIP and hosted carrier. Building on a proven heritage in voice, TalkTalk Business SIP Trunking now combines one of the UK’s largest next-generation networks with tIPicall’s considerable expertise to deliver a market-leading SIP trunking offer.

With the SIP market growing rapidly, TalkTalk Business sees a huge opportunity for their partners to maximize their revenue potential, especially as the switch-off of traditional voice in 2025 approaches, while ensuring an enhanced experience for their own customers.

SIP requires robust and reliable connectivity, so TalkTalk Business is committed to offering their partners peace of mind, knowing they can reply on a proven end-to-end service, regardless of a customer’s choice of PBX and Unified Communications platforms.

Guy Miller, Director of Next Generation Voice Services, TalkTalk Business, said: “Although we have managed to maintain a good degree of interoperability for our SIP offering in the past, the launch of our new service highlighted the need for a fast and effective approach to testing and certification that would allow us to address the widest possible market opportunity.”

“TalkTalk Business SIP trunking offers attractive cost savings and centralized management advantages over its rivals, but ensuring that it works with the leading PBXs is critical – and with the variety of PBX platforms in the UK market, each with multiple versions, verification becomes a challenge.”

With this in mind, Talk Talk Business approached tekVizion to provide SIP interoperability testing and certification services for a number of leading PBX and UC platforms, to help accelerate the availability of a complete solution to their channel partners and customers.

“tekVizion is helping us to certify a range of PBXs rapidly and consistently to help us get and stay ahead of customer needs. Rather than being dependent on scarce and valuable internal resources and the different levels of support and varied processes of the PBX vendors, our collaboration with tekVizion has streamlined the testing process, delivering consistent high-quality results and accelerating our market readiness.”

Chakra DeValla, CEO of tekVizion, added: “We’ve been delighted to support TalkTalk Business in its plans to develop the UK SIP trunking market with an innovative product and a strong focus on interoperability.”

tekVizion works with major PBX and UC vendors and leading service providers worldwide to accelerate SIP service deployments with reduced cost and improved customer satisfaction.
