"CallTower Review"
4/5
What do you like best about CallTower?

The system works fairly well with a few issues. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

We are having trouble where some incoming calls display an internal team member's name instead of the originating caller's caller ID. I have a ticket (Case Number: 01562616). I provided the information about the call but it was over a week old so they could not see it. (That is silly, in my opinion) Now they keep wanting to close it the ticket because it is taking me a while to find another more current example. They should not even ask me to close ticket unless the issue is actually resolved. I understand they are probably under pressure to close tickets but it is not resolved. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you for sharing your experience and for choosing CallTower. We’re glad to hear that our system is supporting your customer communications, though we understand your concerns regarding the caller ID issue and support ticket process.

Your feedback about ticket handling is very important to us. We agree that tickets should remain open until the issue is fully resolved, and we will review this case internally to ensure it’s addressed appropriately. We appreciate your patience as we work to identify a current example and resolve the problem permanently.

We truly value your partnership and will continue striving to improve both our platform and our support experience to better serve your needs.
