"Seamless Transition to Cloud with CallTower"
5/5
What do you like best about CallTower?

I use CallTower as our PSTN provider with Webex Calling, and I love how it connects multiple campuses' phone numbers all in one cloud phone carrier. The setup was easy to port all our numbers, and whenever we've had to raise a support ticket, the responses have been timely. Having someone from CallTower ready to answer questions and assist with the number porting to the cloud was fantastic. We transitioned from using multiple phone companies to just one cloud-based provider, and the process was very structured with good instructions. I also appreciate the assistance we received during the migration, which made it seamless. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

at this time there isn't anything going on that I dislike Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you so much for sharing your experience with CallTower! We're thrilled to hear that your transition to the cloud was seamless and that our team was able to provide the support and guidance you needed during the migration process. Simplifying communication across multiple campuses and consolidating providers is exactly what we aim to achieve, and it's wonderful to know that our structured setup and timely support made a positive impact for you.

Your feedback about the ease of porting numbers and the responsiveness of our support team truly means a lot to us. At CallTower, we strive to ensure that every customer feels supported and confident throughout their journey with us. We're also glad to hear that you're enjoying the benefits of having all your phone numbers connected through one reliable cloud carrier.

If there's ever anything more we can do to enhance your experience, please don't hesitate to reach out.

2.5/5
What do you like best about CallTower?

Most of the time, the cases are resolved quickly. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

There have been a couple of instances where cases have had delayed answers or closed altogether without any subsequent communication that the request has been processed. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you for your review and for sharing both the positives and the areas where we can improve.

If you experience situations where our service falls short of expectations, please don't hesitate to reach out to our management team. Feedback like yours helps us identify process gaps, better understand specific concerns, and take the necessary actions to improve both the customer experience and our internal processes.

We appreciate your feedback and look forward to continuing to support your team.

"Reliable Voice Integration for Microsoft Teams"
0/5
What do you like best about CallTower?

I find CallTower to be an excellent platform for streamlining our telecommunications, especially when linking phone numbers to Microsoft Teams. Its VOIP services are integrated reliably with Teams, which makes it a dependable choice for our communications needs. One of its standout features is the smooth handling of phone number provisioning, porting, and routing. Additionally, I appreciate the ease of managing day-to-day tasks like assigning phone numbers and overseeing routine changes, despite the portal's potential for improved intuitiveness. The service is consistently reliable and well-integrated, contributing to a strong support system. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

I find that the admin portal could be more intuitive, especially when managing larger batches of numbers or making routing changes. While the current management and day-to-day user experience with CallTower is generally straightforward, the portal's usability could be improved to make these tasks easier. Additionally, I believe there's room for improvement in port transparency, which would enhance the overall experience. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you for taking the time to share your experience with CallTower! We're glad to hear that our reliable communication solutions and support have met your expectations. Your feedback regarding the web portal is appreciated—we're continuously working to enhance the user experience and will share your input with our development team. It's great to know that enabling Direct Inward Dialing (DID) through Microsoft Teams is helping to streamline your communication infrastructure. We’re proud to be part of your journey toward greater efficiency!

"One of the best in the industry:"
4/5
What do you like best about CallTower?

CallTower staff are knowledgeable and responsive. It feels like they are interested in partnership, not just being a vendor. Their integration with Microsoft is top notch and unlike most other providers. The broad range of services they offer are icing on the cake. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

There is too much emphasis on self-service and not enough direct customer support. Relying on a portal for nearly every task is frustrating, especially since the portals are hard to navigate and often require switching between several different interfaces. It becomes extremely challenging to obtain operationalized reporting from any source, making it difficult to truly understand how your services are performing. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you for your feedback! Providing excellent service and support is a top priority for us, and we're glad to hear that we're meeting your expectations in these areas.

We're sorry to hear that you've experienced difficulties deciphering certain billing actions within our portals. Your feedback is invaluable, and we will work to enhance the clarity and depth of information provided in our portals to better meet your needs.

It's great to hear that our MS Teams voice solutions are benefiting your organization. We strive to offer competitive plans and pricing to ensure our customers receive the best value in the market. Thank you for choosing CallTower as your partner, and we look forward to continuing to support your business needs!
