Telzio is a cloud based service that lets you rent a phone number in many countries and forward a phone call to your mobile or office phone. It also comes with a basic IVR. Telzio doesn’t appear to have any advance contact center features – no CRM, no agent management, no email marketing, no helpdesk. If you are looking for a free Telzio alternative, available both in cloud and on-premise, with open source code access, give Bitrix24 a try.
