Top two on-premise IP-PBX UC Appliance Manufacturers

Our second manufacturer, Sangoma, incorporates all of our initially discussed requirements (part one- Best On Premise PBX Manufacturers) into two well thought Asterisk IP-PBX server appliances, FreePBX and PBXact. For those that demand control of their system using Asterisk and FreePBX, the well tested, hardened PBXact line comes with several optional levels of support available directly from the manufacturer. These locked systems have been meticulously tested for flawless operation under various conditions. For those companies that require SLAs (Service Level Agreements) these support options can be a critical requirement.
For companies that demand individual granular control, the FreePBX line incorporates the quintessential server choice, because Sangoma, now the owner of Asterisk and FreePBX, designed them. The largest PBX companies have taken notice of Sangoma, who since acquiring Schmooze and FreePBX in 2015 went on to acquire Digium and Asterisk® in late 2018. They have become a dominate provider of effective communications solutions. And not to lie still, they subsequently went on to acquire VoIP Innovations in late 2019 and LLC in 2020.
