  • Accessible Anywhere: CloudTalk is a completely cloud-based business phone system – all you need is to set up your CloudTalk account. But don’t worry, if you already have an existing infrastructure, CloudTalk can be easily linked to it. Switch between your laptop and your cell phone easily.
  • Smarter Calls: Distribute all calls to your team in a smart way and view past customer interactions during the call to enhance customer experience. Native integrations with CRM, helpdesk or other popular apps boost your productivity and take lots of manual tasks out of your workflow.
  • SLA: A service level agreement can be provided for all CloudTalk PBX business phone systems, guaranteeing a maximum level of reliability and technical support.
  • Reliable Operation with 24/7 Monitoring: We always make sure your data and voice services are safe. All data (including VoIP itself) are stored in secured locations of Amazon AWS with 24/7 monitoring provided by CloudTalk experts.

Key Features

With CloudTalk advanced features, your phone experience will get to a whole new level.

  • ACD: Automated smart and efficient queue distribution of inbound calls based on all available data to make sure that callers are always directed to the most qualified agent or agent group.
  • IVR: Create your multi-level interactive voice response (IVR) menu to guide the caller through different options. Make sure they are always directed to the right department, agent or group of agents and that they are receiving relevant information through customized messages.
  • Call Queuing: Create customized call queues. Inbound calls are sorted in call queues based on pre-defined rules and steered to available agents within the right group. Personalized messages are available as well.
  • Call Recording: CloudTalk can automatically make a recording of all calls. Once the call ends, you can listen to it directly from your internet browser anywhere and anytime. Improve customer interactions by monitoring your team’s calls.
