"Seamless Switch with Top-Notch Support"
4.5/5
What do you like best about CallTower?

CallTower was especially helpful in transferring our entire number block from our old system. They have an excellent, very fast, and very friendly support team. Their prices and service uptime are top notch. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

I think the billing center for managing bills and invoices could use a little bit of love. The interface is just a little slow and clunky. It looks a little outdated. It's not particularly easy to navigate. And user management is a little iffy. Review collected by and hosted on G2.com.
