If you are looking for a 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 a contact center for inbound and outbound calls. In addition, you can connect other communication channels, if you have them, and collect incomings in one place. Bitrix24 offers quality control, automation, efficient management, call analytics and the opportunity to run professional campaigns. 

It’s also the only VoIP system that comes with fully featured free CRM. Importantly, when your clients call you from a phone number recorded in CRM, they will be identified, connected to the assigned manager and their phone call will be logged and recorded, if necessary. All interactions with the client are recorded and logged though, not just calls. So if you need to send SMS or use WhatsApp to the same client you had a call with, Bitrix24 can help you with it. bitrix24 is not just a business VoIP system, but the very best VoIP system that will support your business from all sides.

Bitrix24 is available in the cloud and on-premise as self-hosted software that can be installed on your server (the latter version comes with open source code access).
