"Reliable Service and Great Value, But Hardware Delivery Needs Improvement"

4.5/5

What do you like best about CallTower?

This has been a mostly worry-free service for us since our implementation. Service is effective, account management is relatively easy, pricing is good. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

If there was one nit to pick it would be around hardware timing - any time we need replacement phones it always takes longer than it should - both the ordering process and the shipping timeline. That's a definite area of improvement. Review collected by and hosted on G2.com.

"Review of CallTower transition with Microsoft Teams integration in GCC High"

4/5

What do you like best about CallTower?

CallTower is one of a few companies that support GCC High Teams environment. It was very easy to transition from our TSP to the Call Tower Teams solution. The service has been very good and we are quite happy with the overall experience. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

This is not an inexpensive service, and there are some costs that are not seen on the Teams backend like Microsoft licensing that have annual fees. Overall the costs have been significantly reduced on the calling side, but the licensing costs have increased. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

edit

Thank you so much for your thoughtful review and for choosing CallTower to support your GCC High Teams environment! We're thrilled to hear that your transition to our solution was smooth and that you've had a positive experience with our service.

We truly understand the importance of transparency when it comes to costs, especially in highly secure environments like GCC High. Your feedback regarding licensing clarity is greatly appreciated, and we’re continuously working to make these aspects more visible and easier to manage for our customers.

It’s great to know that our direct Teams integration eliminated the need for additional on-prem hardware and provided a seamless, cloud-based voice experience. Helping organizations streamline their communications while maintaining compliance and security is exactly what we aim to do.
