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.

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.

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.
