Cost-Effective Service with Setup Hurdles
What do you like best about CallTower?
I like the cost and the service that CallTower provides. We need phone service, and CallTower provides low-cost, good quality phone service and tech service through Teams. The reliable phone service and the ability to text message from within Teams is very convenient.
What do you dislike about CallTower?
The CallTower CT connect portal where we administer our phone numbers is antiquated and it has several friction points. It's just not easy to navigate. It's not intuitive. The porting process was a disaster. It took months, much longer than we were originally told. Communication with the project manager was pretty bad initially.
What problems is CallTower solving and how is that benefiting you?

One-Stop Shop for Seamless Telecom Integration
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.
