## CallTower Reviews
  ### 1. One-Stop Shop for Seamless Telecom Integration

**Rating:** 4.5/5.0 stars

**Reviewed by:** Antonio F. | Enterprise (> 1000 emp.)

**Reviewed Date:** April 24, 2026

**What do you like best about CallTower?**

I like CallTower because it's a one-stop shop for our needs. They provided great support to migrate from our existing platform to Microsoft Teams and assisted in building menus. They're also excellent in configuring and supporting devices. This all-in-one support has simplified our processes, including migrating all numbers to one carrier which makes billing easier. The resources assigned were really knowledgeable and helpful, making the setup process very easy for us, even though it was our first time doing anything like this. I recommend them all the time and would give them a nine out of ten.

**What do you dislike about CallTower?**

I could use some help with improvement on managing new projects. There's some new technologies and opportunities getting shared with us, but not all fit into our current working model. One of them is the rent-to-own option, which is continually presented to me despite having expressed that I'm not interested.

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

CallTower consolidates our DIDs to one vendor, simplifying invoicing, troubleshooting, and support.

**Official Response from Tonya W.:**

> Thank you for taking the time to share your experience with CallTower. We are glad to hear that our team was able to support a smooth migration to Microsoft Teams and provide the hands-on guidance, device support, and number consolidation that made the process easier and billing more manageable. 

It means a lot to know our resources helped make a first-time project feel straightforward. We also appreciate your candid feedback around how new technologies and options are introduced. Your input is valuable and helps us improve how we align recommendations with each customer’s operating model. T

hank you again for your trust and for recommending CallTower.

  ### 2. Seamless Microsoft Teams Integration with CallTower

**Rating:** 3.5/5.0 stars

**Reviewed by:** Nic S. | Lead Customer Relations Specialist, Small-Business (50 or fewer emp.)

**Reviewed Date:** April 22, 2026

**What do you like best about CallTower?**

I like CallTower because I don't have to think about it; it just works, and that's fine with me. I'm very pleased with how the calls work, which is the main feature I use. It's integrated with Teams, which is exactly what we wanted and the only thing we need it for. The porting process was good, and the phones worked immediately, making the setup generally easy enough.

**What do you dislike about CallTower?**

The initial setup process with CallTower varied depending on the user's tech savviness. While the porting process was good and phones worked immediately, adjusting individual settings in Teams could be a little tricky.

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

CallTower provided us with a convenient solution for integrating Microsoft Teams, which is exactly what we needed.

**Official Response from Tonya W.:**

> Thank you for sharing your feedback with us. It is great to hear that CallTower has been a solution you do not have to think about and that everything simply works the way you need it to. We are glad the calling experience has been smooth, the Teams integration fits your needs, and the porting and setup process made getting started easy for your team.

We appreciate your note about the initial setup varying based on each user's comfort with technology. Even though the porting went well and the phones worked right away, your insight about adjusting individual settings in Teams helps us understand where we can continue to simplify the experience.

It is also encouraging to know that CallTower has provided the convenient Microsoft Teams integration your organization was looking for. Supporting a reliable and familiar communication experience is exactly what we aim to deliver.

  ### 3. Seamless Transition, Robust Support

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Non-Profit Organization Management | Mid-Market (51-1000 emp.)

**Reviewed Date:** June 02, 2022

**What do you like best about CallTower?**

I really appreciate how CallTower made it simple for us to convert from a physical phone system to a web-based system. This transition has allowed our users to be connected on the same phone system wherever they are, which is really helpful. CallTower did a really good job setting up our environment when we first onboarded with them, and we've had no problems with the system in three years. I'm also really happy with the support we receive whenever we have questions. It brings cohesiveness from a telephone experience, especially since we have users in 20 different states, and our customers can communicate seamlessly with us.

**What do you dislike about CallTower?**

The limitations more have to do with Microsoft Teams than with CallTower. The actual initial setup was quite complicated, and the engineers definitely had an engineering thought process in the method that the setup was done.

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

CallTower made it simple to convert from a physical phone system to a web-based one, allowing users to be on the same system wherever they are. It's really helpful.

They were able to layer the features that we needed to our MS Teams platform.  The available apps create a unique experience for each user based on their individual needs.

Nothing comes to mind.  The fact that we rarely (if ever) need to contact them speaks volumes.

We moved to MS Teams and CallTower is the service provider for the VOIP associated with it.

**Rating:** 5.0/5.0 stars

**Reviewed by:** Mike G.

**Reviewed Date:** December 17, 2025

**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.

**What do you dislike about CallTower?**

at this time there isn't anything going on that I dislike

  ### 9. Reliable Voice Integration for Microsoft Teams

**Rating:** 0.0/5.0 stars

**Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** April 30, 2025

**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.

**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.

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

I find CallTower streamlines telecommunications with reliable phone number management integrated into Microsoft Teams, making provisioning, porting, and routing smooth. Managing users and routine changes is straightforward, though the admin portal could be more intuitive.

**Reviewed by:** Verified User in Hospital & Health Care | Enterprise (> 1000 emp.)

**Reviewed Date:** April 23, 2024

**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.

**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.

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

They are our partner for leveraging MS Teams for voice, and their plans and pricing are very competitive in the marketplace. In addition, we make use of their fax services, text-to-Teams integration, virtual analog phone services, and virtual fax services.

**Rating:** 2.0/5.0 stars

**Reviewed by:** Lauren D.

**Reviewed Date:** February 12, 2026

  ### 28. Reliable Service and Great Value, But Hardware Delivery Needs Improvement

**Rating:** 4.5/5.0 stars

**Reviewed by:** Brian W. | IT Manager, Mid-Market (51-1000 emp.)

**Reviewed Date:** October 24, 2025

This has been a mostly worry-free service for us since our implementation. Service is effective, account management is relatively easy, pricing is good.

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.

It provides our Teams calling platform. While hard phones are virtually gone from our environment, the overall layout remains sound.

  ### 29. Review of CallTower transition with Microsoft Teams integration in GCC High

**Rating:** 4.0/5.0 stars

**Reviewed by:** Dennis S. | Network Engineer Project Manager, Mid-Market (51-1000 emp.)

**Reviewed Date:** July 25, 2025

**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.

**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.

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

With Call Tower we no longer needed a dedicated telephone service. It integrated directly into our Micrososft Teams environment.  This did not require any additional software or hardware onprem and the integration in Teams has been very seamless for our company.

  ### 43. Teams VoIP Works Great for Our Microsoft-Heavy Organization

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Non-Profit Organization Management | Mid-Market (51-1000 emp.)

**Reviewed Date:** April 28, 2026

**What do you like best about CallTower?**

As a Microsoft-heavy organization, the Teams VoIP system has worked very well.

**What do you dislike about CallTower?**

Support has been less than expected and we are charged for any change requests submitted.

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

We had an antiquated phone system that was not flexible and required a lot of support. The Call Tower solution fixed that.

  ### 44. Affordable Connectivity with Some Rough Edges

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Retail | Mid-Market (51-1000 emp.)

**Reviewed Date:** February 24, 2022

**What do you like best about CallTower?**

I really like the price of CallTower and find their account management team very easy to use. They are really responsive and easy to work with, which is great. The support structure is also easy to work with, which is important for us.

**What do you dislike about CallTower?**

CT text is pretty clunky and not a favorite among our users. They still prefer Apple texting, but because CT text is business numbers, then they use that. The interface could be easier to get to from both PC and phone. The initial setup was the roughest part because of the porting of numbers. It took extraordinarily long to do.

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

CallTower provides PSTN connectivity for our phones.

**Official Response from Kade Herbert:**

> Thank you for your review! We appreciate this constructive feedback.

  ### 45. 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. 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.
