"Reliable VoIP Solution with Minor Admin Hiccups"
4/5

I find CallTower to be a reliable platform for our Teams VoIP solution. It replaced an antiquated phone system, which was a significant improvement for us. The initial setup was straightforward, especially with the help of CallTower's technical support. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

The portal can be clunky to use for administering our DIDs (adds, changes, deletes). It can be hard to figure out how to add a new number to one of our locations, especially for someone that does not do it that frequently. Review collected by and hosted on G2.com.

It functions smoothly with Teams Voice, and as far as I know, we haven't encountered any problems with our service. Review collected by and hosted on G2.com.

We were enrolled in autopay, but the amount withdrawn from our bank account seldom matched the statement balance. There were frequent billing adjustments, and as far as I could tell, there was no option to automatically pay the exact statement balance. Review collected by and hosted on G2.com.
