CallTower Review **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Manufacturing | Mid-Market (51-1000 emp.) **Reviewed Date:** August 21, 2025 **What do you like best about CallTower?** The system works fairly well with a few issues. **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. **What problems is CallTower solving and how is that benefiting you?** They are allowing us to communicate with our customers. **Official Response from Tonya W.:** > Thank you for sharing your experience and for choosing CallTower.
