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. **Official Response from Kade Herbert:** > Thank you so much for writing a review! We will be using your feedback. ### 4.

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.

One of the best in the industry: **Rating:** 4.0/5.0 stars **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.
