CloudCall by Synety is a British-based cloud telephony solution that comes with a standard set of features and pricing policy. You pay 20-30 pounds a month and get incoming and outgoing phone calls, ability to rent local phone number, record phone calls and so on. If you are looking for a free CloudCall alternative, check out Bitrix24. The first advantage is that Bitrix24 is 100% free for 12 users. The second advantage is that Bitrix24 is a fully featured CRM and call center in one, so you don't have to spend any money on CRM consultants. The third advantage is that Bitrix24 is available both in cloud and as self-hosted software that can be deployed on-premise, using your own server (you'll get open source code access if you opt for this).
