I've been using Callscaler for a few days and I'm impressed with its performance. The user interface is intuitive and makes it easy to track and analyze my calls. The software provides me with valuable insights into my marketing campaigns, helping me optimize and improve my strategies.

On the downside, the reporting feature could be a bit more robust, but it's not a deal-breaker for me. Another potential improvement would be to have more customization options for call notifications. However, these are minor issues and don't take away from the fact that Callscaler is a solid call tracking software.

In terms of customer support, I've only had to reach out once for clarification on something and the response was prompt and helpful. Overall, I'd recommend Callscaler to anyone in need of a reliable and efficient call tracking solution.
