Free Business VoIP System

If you are looking for a free VoIP phone system for your small business, Bitrix24 is what you need. Unlike other voip solutions, Bitrix24 works both as your internal PBX system and as contact center for inbound and outbound calls. It’s also the only free voip system that comes with fully featured free CRM. Importantly, when you clients call you from a phone number recorded in CRM, they will be identified, connected to assigned manager and their phone call will be logged and recorded, if necessary. Bitrix24 is available in cloud and on premise as self hosted software that can be installed on your server (the latter version comes with open source code access).
