If you Google 'free CTI software', 'free CTI system', 'free CTI client' or 'free CTI server', you won’t find any other solution that gives you as many computer telephony integration options free of charge as Bitrix24. We can afford to give away our CTI solution, because we make money via phone number rentaloutbound phone calls and SIP connector. In addition to that our free cloud CTI serves as great advertisement for premium self hosted Bitrix24 editions. 

Any CTI starts with a 'screen pop' – a callerID popup windows that shows client information who your agents are currently talking with including history of past interactions. Bitrix24 also automatically logs and records all phone calls, if necessary. Canned 'this phone call is recorded' message is included, as are greetings and on hold melodies. CDRs (call detail records) are available as well.

Because our CTI is extremely popular among small businesses and large call centers alike, you can think of it as a cross between business phone system and telemarketing software. Imagine 'Salesforce' and 'Asterisk' in one and this is what Bitrix24 is like. ICR, ACD (call queuing), CLI (ANI), DID (employee extensions), voice mail, call forwarding, call transfer, phone hour settings, click to dial, iOS/Android smartphone support, CRM, helpdesk (self hosted Bitrix24 only), videoconferencing, instant messaging, agent management and a number of other features are available to you as well both in free and premium Bitrix24 plans, in cloud or on premise.
