OTE Group – Sangoma Technologies

Prior to 2016, OTE Group primarily used Microsoft Lync for their internal communications in the company. The main challenge with this setup was that the customer was unable to upgrade Microsoft Lync 2013 based IP telephony system to Skype for Business Server (SBS) as existing phones deployed were not supported for SBS. This was a critical challenge as it led to dependency on the phone vendor to provide upgraded firmware for phones to be operational with Lync. OTE uses IP phones from multiple vendors and the presence of more than one Microsoft certified partner in the picture complicated this challenge further. The main challenges faced by the customer were:  Upgrade to a phone system that supports multiple phone brands  Avoid costly Lync licenses  Save on time and human resources managing the phone systems  Setup a professional and easy to maintain phone system for the company Due to the nature of their partnerships, the need for a state-of-the-art communication system was of paramount importance to the company. Having deployed Sangoma Session Border Controllers (SBC) with their Lync infrastructure, OTE group was familiar with the best-in-class quality and resilience provided by Sangoma solutions. The versatility of the products and the ability to scale had impressed them. In the year 2016, the company made the decision of implementing a Sangoma phone solution – complete with FreePBX and feature add-one (AKA commercial modules), IP phones and Gateways.
