UniVoIP Expands Microsoft Teams Voice with Operator Connect, Aims to Fill Channel Gaps, Podcast

Channel Partners 2025 | By Doug Green

“If your customers are using Microsoft Teams but still relying on a third-party phone system, you’re leaving money on the table.” That was the bold message from Dean Manzoori, CEO of UniVoIP, during our conversation at Channel Partners. Manzoori isn’t just pitching a product—he’s outlining one of the clearest opportunities for the channel in 2025. UniVoIP is expanding its cloud voice solution for Microsoft Teams with support for Operator Connect, Microsoft’s fast-growing platform for direct PSTN integration. For channel partners and MSPs, that means a frictionless path to deliver full Teams voice capability—supported by automation, real-time number provisioning, and a management layer built for scale.

From Hosted PBX to Teams Native

Manzoori brings over 30 years of experience in telecom. As a founding member of the Cloud Communications Alliance and UniVoIP’s former Chief Technology Officer, he has been at the forefront of unified communications since the Hosted PBX era. Now, as CEO, he’s leading UniVoIP’s next evolution.

“We saw the Teams opportunity coming as early as 2017,” said Manzoori. “By 2019, we had fully pivoted to become the best voice provider for Microsoft Teams.”

UniVoIP’s onboarding process is fully automated and designed for businesses of all sizes. One standout feature is intra-ID synchronization, which enables seamless number assignments across both the UniVoIP portal and Microsoft Teams Admin Center—giving users and admins maximum flexibility.

Built for the Channel, with the Channel

What sets UniVoIP apart is its partner-first platform, developed with direct input from the channel. Partners have complete visibility across tenants, with a single sign-on experience for quoting, provisioning, ticketing, and ongoing support.

“We don’t just sell PSTN access,” Manzoori emphasized. “We provide analog support, contact center integration, texting, paging, and more. And we remove the uncertainty from Teams voice deployments.”

With over three years of delivering Teams-native voice and a 100% customer retention rate, UniVoIP’s expansion into Operator Connect marks a milestone in their channel commitment—and a major opportunity for partners looking to grow revenue while delivering lasting value.
