"Affordable Simplicity with Great Support"
4.5/5
What do you like best about CallTower?

I appreciate CallTower’s awesome and very helpful service as I use it at my company. I love the simplicity of the portal, which makes user interaction easy and efficient. The updates sent directly to my email are incredibly useful, keeping me informed. The setup process is straightforward and cost-effective, making CallTower an affordable solution for the organization. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

I find some challenges with the tech support system, particularly that if we don't respond quickly to a case, it gets closed within an hour. This is especially problematic for priority one and priority two issues, where more time is needed to address and resolve concerns adequately. Review collected by and hosted on G2.com.
