About

Adversus is an outbound dialing solution that helps you streamline your call strategies, automate manual processes, and provide valuable insights to improve your outbound workflows and efficiency. Adversus was born in 2015 after our founders experienced a lack of flexibility with the solution they worked with. The dream was to build an outbound solution that would change the game․ We believe in user-driven innovation, and we acknowledge that every single user has different needs and demands. We provide a solution that incorporates flexibility and customization to every aspect of the workflow. At Adversus, our primary focus is to have a future-proof solution that never falls behind. We do not just want to adapt to the market but instead push the boundaries of what is possible. Adversus is used by businesses in a wide range of industries, with the common goal to make their outbound call activities more efficient. The size ranges from one to several hundred end-users.

Pros & Cons from Real Users

Pros

  • CallTools offers excellent customer service. David has been incredibly helpful in walking me through the system, explaining each feature in detail, and making sure I feel supported. The platform itself has powerful tools that can really elevate your workflow once you understand how to use them.
  • CallTools has everything: 1. Voice 2.SMS 3.Email 4. Dialer strategy. etc All of its features makes it really easy for any company to provide best customer service and be profitable too. its tough to find something like CallTools at this cost in the market.
  • The customer service and the dialer services perfect i will recommend to other people. I will also be using this service for my business long term
  • When calling in, they get someone to help you right away. And everyone that I have spoken too, has been amazing, kind and knowledgeable.
  • Ease of use

Cons

  • Calls and trainings cannot be recorded, which makes it difficult to review the steps later. I often find myself needing additional support to remember how to use certain features. It would be extremely helpful if CallTools added a section with video tutorials covering all the available features, so users can learn and revisit the material at their own pace.
  • I can just think and waiting of them having Phone apps as well making CallTools no. 1.
  • N/A.
  • I have had such a great experience so far, that i haven't found a negative thing about CallTools.
  • System doesn't do a great job of alerting us if our #s are spam.
