"Great Communication - Easy Process"

5/5

What do you like best about CallTower?

I really enjoyed the Project Management Dashboard that our CallTower PM worked with us on and the effective and prompt communication. We also greatly appreciated the flexibility when needing to set up calls to gain more clarification on specific processes and required information. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

There weren't necessarily any dislikes or downsides that I came across during the process of setting up our company's VoIP numbers and Auto Attendant. Once we had the required information from our side to complete the Onboarding documents/spreadsheet, things were smooth sailing. Review collected by and hosted on G2.com.

What problems is CallTower solving and how is that benefiting you?

CallTower has assisted us in setting up our very first iteration of Business Phone lines and Auto Attendant to help support us in better company communications.

This is benefitting us by having designated company phone lines that are separated from our personal phones and can be dedicated and associated to our company. Review collected by and hosted on G2.com.

"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.

"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.

"Efficient License Procurement with Call Quality Support Challenges"

4/5

What do you like best about CallTower?

I really appreciate the marketplace and the ability to self-serve with licenses that CallTower offers. This functionality allows us to obtain licenses efficiently without having to rely on quotes or reach out to someone for assistance. It's a significant time-saver for my team and me. The process of procuring telephone lines has been smooth, and any initial challenges we faced with license procurement were quickly resolved. Furthermore, CallTower excellently solves onboarding processes and call quality issues, making overall communication within our teams more effective. I find the integration with Microsoft Teams particularly useful, enabling us to leverage its capabilities seamlessly. All these factors combined make CallTower an appealing choice that I would consider repurchasing and recommend to others. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

"Reliable Service and Great Value, But Hardware Delivery Needs Improvement"

4.5/5

What do you like best about CallTower?

This has been a mostly worry-free service for us since our implementation. Service is effective, account management is relatively easy, pricing is good. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

If there was one nit to pick it would be around hardware timing - any time we need replacement phones it always takes longer than it should - both the ordering process and the shipping timeline. That's a definite area of improvement. Review collected by and hosted on G2.com.

"Review of CallTower transition with Microsoft Teams integration in GCC High"

4/5

What do you like best about CallTower?

CallTower is one of a few companies that support GCC High Teams environment. It was very easy to transition from our TSP to the Call Tower Teams solution. The service has been very good and we are quite happy with the overall experience. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

This is not in inexpensive service, and there are some costs that are not seen on the Teams backend like Microsoft licensing that have annual fees. Overall the costs have been significantly reduced on the calling side, but the licensing costs have increased. Review collected by and hosted on G2.com.

Response from Tonya Wheatfall of CallTower

Thank you so much for your thoughtful review and for choosing CallTower to support your GCC High Teams environment! We're thrilled to hear that your transition to our solution was smooth and that you've had a positive experience with our service.

We truly understand the importance of transparency when it comes to costs, especially in highly secure environments like GCC High. Your feedback regarding licensing clarity is greatly appreciated, and we’re continuously working to make these aspects more visible and easier to manage for our customers.

It’s great to know that our direct Teams integration eliminated the need for additional on-prem hardware and provided a seamless, cloud-based voice experience. Helping organizations streamline their communications while maintaining compliance and security is exactly what we aim to do.
