"Great project management and service."
4/5
What do you like best about CallTower?

Calltower took time and great detail to implement our project. Project manager is very responsive and addressed questions and issues promptly. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

Having two places to manage phone system (Call tower portal and Teams admin) is a bit of pain. About 50% of project also needs to be done by the customer as they won;t go to your old system (e.g. Nextiva) to pull out information and designs for auto attendants and call queues. The customer must do all these prep work. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you for taking the time to share your feedback! We’re so glad to hear that you had a positive experience with our project management and service, and that our team was responsive and thorough in guiding your implementation.

We also appreciate your candid feedback regarding managing phone systems across two portals and the prep work required from customers. This type of input is invaluable as we continue to refine our processes and enhance the CallTower Connect portal to simplify administration and reduce manual steps for our customers.

It’s great to hear that you’re already seeing benefits through cost reduction and seamless Microsoft Teams integration—that’s exactly the outcome we strive to deliver. We look forward to continuing to support your organization and making your experience with CallTower even better.
