Seamless Migration from Legacy Telephony to Microsoft Teams Phone System


Tecpetrol had been using Cisco CallManager and Skype for Business for their business communications but began looking for a single platform solution to unify their communications infrastructure. Their desire to integrate stemmed from wanting to minimize communication complexity, as well as reduce operational expenses.

Tecpetrol searched for an all-in-one solution that could deliver both unified communications (UC) and collaboration.

Tecpetrol wanted to utilize Microsoft Teams as their UC and collaboration platform for communications and meetings, but it was important for them to create a seamless transition for their users.

This change started with implementing an independent video conferencing system that enhanced their employees’ collaboration, communication and teamwork.

With this new video conferencing platform, Tecpetrol was able to host live events on Microsoft Teams. This helped them strengthen the adoption of Teams throughout their organization and quickly became their preferred platform for UC and collaboration.

However, Tecpetrol still relied on Cisco’s infrastructure to communicate between their headquarters and other offices located throughout Latin America. They also needed the capability to communicate with their customers who were using Microsoft Skype for Businesses as their enterprise voice and video communications platform.

Tecpetrol’s strategy was to analyze different migration scenarios to minimize possible impacts and reduce the risks associated with migration. They wanted to unify their offices and PBXs locally using hardware SBCs on premises and core software SBCs that would integrate within their entire operation.

Ultimately, they were aiming for a quick and successful user adoption of Microsoft Teams.

“Because of Microsoft’s great UC platform, our integrator Newtech and AudioCodes’ flexible approach and products, we managed to successfully migrate to Microsoft Teams and improve our customers’ experience and productivity.”
