Press the Green Button: Frisco‑Based Tango Networks Enables Easy Microsoft Teams Calls on Mobile with Dual Personas

In a "bring-your-own-device" world, Tango Extend lets Microsoft Teams users make and receive calls straight from any mobile device's standard dialer. Businesses can control the eSIM in a multi-SIM personal phone, for a secure separation between work and personal calls.

Frisco-based Tango Networks has announced a new solution that enables mobile phones to be an extension of a Microsoft Teams-enabled fixed-line phone number.

Called Tango Extend, it leverages Microsoft Teams SIP Gateway technology to mobilize fixed-line phone numbers, allowing users to make and receive Teams calls through the native dialer on their mobile phone.

“Today’s work-from-anywhere world demands simple and easy-to-operate communications to boost productivity,” Tango Networks President Andrew Bale said in a statement. “Tango Extend brings business communications to any worker in any location. With Tango Extend, business customers can get more from their investment in Teams.”

The company said that Tango Extend seamlessly brings Teams to employees on-the-go and the deskless workforce, such as frontline workers in retail, delivery, transportation, and in-home services.

It said that the frontline workforce is estimated at nearly 2 billion people worldwide, and many of them lack access to corporate communications platforms.

Tango Extend connects them with corporate communications, improving collaboration across the extended workforce, the company said.

“Tango Extend unlocks even greater flexibility and a superior user experience when used in combination with the Operator Connect by NTT solution. The solutions together enable the ability to use the same Teams number and telephony provider to make calls through either the native dialer on mobile phones or the Teams application,” said Charlie Doubek, VP of Managed Collaboration and Communications at NTT, one of the Operator Connect partners for Microsoft Teams. “Global business users can easily mobilize their existing Teams numbers and calling plans across multiple mobile networks.”

A dual persona approach separating business and personal communications

Tango Extend offers a dual persona approach that turns Bring-Your-Own-Device (BYOD) mobile phones into business-ready extensions of Teams.

It allows an eSIM in a multi-SIM personal mobile phone to be controlled by the business, allowing work communications and personal communications to be separated and secured as dual personas.

“Microsoft Teams and Microsoft Teams Phone are powering collaboration and enterprise-grade calling wherever work happens, in the office, at home or on the road,” Mahendra Sekaran, VP of Microsoft Teams Engineering, said in a statement. “Tango Extend provides another approach to deliver voice services to Teams Phone users by extending fixed lines to mobile devices and enabling a single business number that works across endpoints.”

Tango Networks said that the Teams-integrated persona uses the work-controlled SIM and the employee’s Teams identity and number for communications.

Business mobile communications can be centrally captured and recorded for compliance with records retention rules or for customer service quality assurance, the company said.

Personal communications, on the other hand, remain private using the employee’s personal identity and number.

Tango Extend is covered by more than 100 patents and has won more than 10 best new product and channel solution awards, the company said.

Tango Networks Co-Founder and CTO/CISO Andrew Silver, was featured as a force in telecom in Dallas Innovates’ 2023 Future 50. The prolific inventor received his 100th patent in late 2021—many related to Tango’s work giving businesses control over mobile voice, messaging, and data in a “work-from-anywhere world.”
