After the initial port, the porting process has turned into a complete shambles. There is a lot of back and forth between myself, CalllTower and the losing carrier. Review collected by and hosted on G2.com.

"Quick, Easy Microsoft License Management with a Straightforward UI"
4/5
What do you like best about CallTower?

My favorite feature is being able to adjust our Microsoft licenses quick and easily right through the site; no waiting required. Straight forward and easy to use UI. It processes new user setup quickly too. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

The MFA to login is very quirky. Sometimes works, sometimes it doesn't and you have to wait or try multiple browsers to get it to let you in. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you for taking the time to share your feedback. We're thrilled to hear that the CallTower portal helps simplify Microsoft license management and user provisioning, making it faster and easier than working directly through the Microsoft admin center. It's great to know that the intuitive interface and seamless Teams integration are delivering value for your organization.

"One-Stop Shop for Seamless Telecom Integration"
4.5/5
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. Review collected by and hosted on G2.com.

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. 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 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.

"Affordable Service with Great Support, but Reporting Needs Improvement"
4.5/5
What do you like best about CallTower?

I like CallTower for their low price and excellent customer service. They also provide a really stable system. I use the phone service and SMS texting through CallTower that integrates within the Teams application, and it works well. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

Reporting is not good. I have to submit a ticket every month to get user reports. It would be much better if there was just an account I could log in to or an automated report that would send to me. Also, the porting was a nightmare. The porting took way longer than what was promised. Review collected by and hosted on G2.com.

Microsoft licensing management is very important. I'd say we're getting what we pay for. Review collected by and hosted on G2.com.

What do you dislike about CallTower?

The user interface could be improved. The save buttons are too small, and the error processing leaves a lot to be desired. Sometimes the app doesn’t perform as intended, which makes it frustrating to use. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

Thank you for your review. We're pleased to hear that CallTower is helping streamline Microsoft licensing and Teams phone number management while keeping those services in one place.

We also appreciate the constructive feedback regarding the user interface. We understand how frustrating it can be when workflows aren't as intuitive as they should be or when an application doesn't behave as expected.

Your comments have been shared with our team as we continue to enhance the platform and user experience. Thanks again for your partnership and valuable feedback.

"Seamless Microsoft Teams Integration with CallTower"
3.5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Response from Tonya W. of CallTower

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.
