Twilio is one of the most powerful cloud telephony platforms currently available on the market. Twilio reviews are overwhelmingly positive and Twilio pricing is very reasonable. If you are looking for a free Twilio alternative, Bitrix24 offers you a number of advantages, other than the zero price. First, Bitrix24 is available both in cloud and on-premise, with API/REST API available for both and open source code available for the self-hosted editions. Second, Bitrix24 is ready to use in just 30 seconds with minimal setup – you don’t need to integrate anything and all telephony features, such as the ability to rent local or toll-free phone numbers, set up work hours, call recording, internal extensions, forwarding/transfer/queues/voicemail, SIP phones, etc. are available to you out of the box. Third, Bitrix24 comes with free fully-featured CRM and sales automation system, which means that you can have a free call or contact center and pay only for outgoing calls.
