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. **Official Response from Tonya W.:** > Thank you for taking the time to share your experience with CallTower! We're glad to hear that our reliable communication solutions and support have met your expectations. Your feedback regarding the web portal is appreciated—we're continuously working to enhance the user experience and will share your input with our development team. It's great to know that enabling Direct Inward Dialing (DID) through Microsoft Teams is helping to streamline your communication infrastructure. We’re proud to be part of your journey toward greater efficiency! ### 2. CallTower only cares about your money and locking you into a contract **Rating:** 0.0/5.0 stars **Reviewed by:** Murad A. | Small-Business (50 or fewer emp.) **Reviewed Date:** May 16, 2024 **What do you like best about CallTower?** They were helpful only until the point that a contract was signed. No support afterwards. **What do you dislike about CallTower?** They are entirely unhelpful when the service does not perform as expected. We signed up for Microsoft Teams with Operator Connect. Our audio has significant latency, causing us to talk over our customers - which obviously leads to frustration on both ends. CallTower ran some basic tests and said nothing was wrong and if we want any more help it will be $200 per hour. When i inquired about switching to another service still with CallTower, i received no reply whatsoever. Long story short, they do NOT care about any problems that arise after the contract is signed. Once they've guaranteed they are getting paid, you do not matter. **What problems is CallTower solving and how is that benefiting you?** They have not solved any problems. Our service was better before, and now it is much worse and almost unusuable. **Official Response from Tonya W.:** > Thank you for sharing your experience with us. We are genuinely sorry to hear about the issues you've encountered and understand your frustration. At CallTower, we strive to provide exceptional support throughout the entire customer journey, not just during the initial stages. We apologize if we fell short in addressing your concerns regarding the audio latency with Microsoft Teams and the subsequent support process. Your feedback highlights critical areas where we need to improve. We are committed to resolving these issues and ensuring that you receive the support you need. Please reach out to us directly at (800) 347-5444 so we can prioritize your case and work towards a solution. We regret any inconvenience caused and appreciate your patience as we work to make things right. Your satisfaction is important to us, and we are here to assist you in any way we can. Thank you for bringing this to our attention and for allowing us to improve our services. ### 3. Keeps breaking **Rating:** 1.0/5.0 stars **Reviewed by:** Verified User in Industrial Automation | Mid-Market (51-1000 emp.) **Reviewed Date:** August 18, 2023 **What do you like best about CallTower?** It was previously functional. We previously had support. **What do you dislike about CallTower?** It is legacy & we will lose support by the end of the year. Users will not be able to receive calls or go into RONA for no reason. **What problems is CallTower solving and how is that benefiting you?** We need a call center system that runs on SFB, currently Call Tower is going that for us. **Official Response from Tonya W.:** > We're truly sorry to hear about your less-than-satisfactory experience and we sincerely apologize for any inconvenience this may have caused you. We take feedback like yours very seriously, as it helps us identify areas for improvement and ensure a better experience for all our customers. We would appreciate the opportunity to better understand the specifics of your situation so we can address the issues you've faced. Please reach out to our dedicated support team at support@calltower.com so we can work towards resolving your concerns promptly. ### 4. An Astounding Culture of Apathy and Unresponsiveness **Rating:** 0.0/5.0 stars **Reviewed by:** Andrew L. | IT Manager, Enterprise (> 1000 emp.) **Reviewed Date:** December 13, 2022 **What do you like best about CallTower?** Like any other Operator Connect provider, the telephony services that run through Teams are as reliable as Teams is. **What do you dislike about CallTower?** It takes months of repeated calling and emailing to reach any resolution, and we have yet to receive a single correct invoice. In all my years of working with telco providers, I have never worked with a company that cares so little. **What problems is CallTower solving and how is that benefiting you?** They are presently creating problems for our accounting team. It is handy to have an Operator Connect provider for Teams calling, though. **Official Response from Kade Herbert:** > We appreciate you bringing this matter to our attention, rest assured that we will be passing this information to the related parties and we will work hard to make this right. Please reach out to support@calltower.com if you need any service assistance during the interim. Thank you. ### 5. Frustrating for anything besides general call queues **Rating:** 0.0/5.0 stars **Reviewed by:** Rebecca J. | Associate Director, Small-Business (50 or fewer emp.) **Reviewed Date:** January 30, 2023 **What do you like best about CallTower?** The ability to view and monitor calls/agents **What do you dislike about CallTower?** Not compatible with much of what we do, even though we had been assured it was. **What problems is CallTower solving and how is that benefiting you?** They try, but I think it is more of a compatibility issue. **Official Response from Kade Herbert:** > Thank you for your feedback, we will be sure to take it into account and make changes. If you need any assistance from CallTower, please reach out at support@calltower.com ### 6. Many outages **Rating:** 0.0/5.0 stars **Reviewed by:** Verified User in Government Relations | Mid-Market (51-1000 emp.) **Reviewed Date:** June 02, 2022 **What do you like best about CallTower?** Nothing. Would not recemeend it. False promises with SalesForce integrations. **What do you dislike about CallTower?** I haven't used Call Tower for 2 years. I am still paying for it since a signed a 3 years agreement. I can't wait until my contract is up. We were down for entire days at a time without a response. I switched to Five9 and everything works perfectly. There is a huge disconnect between your partners. I would open a ticket and would be down for at least 24 hours multiple times. I wouldn't hear anything until the next day. I was forced to switch to a service that works, but I still pay my CallTower bill. **Recommendations to others considering CallTower:** Use another service **What problems is CallTower solving and how is that benefiting you?** It is not benefiting me at all. I haven't used it for years **Official Response from Kade Herbert:** > We're sorry to hear about your experience. If you need assistance during your contract, please reach out to support@calltower.com. ### 7. IT started out good back before Appia was bought by Call Tower, but it has gone down hill ever since **Rating:** 0.0/5.0 stars **Reviewed by:** Brentt G. | Chief Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** May 13, 2022 **What do you like best about CallTower?** not much anymore, the tech support is clueless, and the service is not reliable like it used to be **What do you dislike about CallTower?** their contracts are a mess and they use them to hold onto you even when service outages are frequent **What problems is CallTower solving and how is that benefiting you?** none, we are actually moving all of our voip systems away from it due to the drop is quality of their business **Official Response from Kade Herbert:** > We're sorry to hear about your experience. If you have remaining issues, please contact us at support@calltower.com for prompt assistance. ### 8. Crooked leadership **Rating:** 0.5/5.0 stars **Reviewed by:** Jim C. | Small-Business (50 or fewer emp.) **Reviewed Date:** January 01, 2020 **What do you like best about CallTower?** Not much. Tech support is typically helpful. **What do you dislike about CallTower?** As a reseller, look elsewhere. Once you start adding clients, the Chief Revenue Officer will pull your commissions and steal your clients. The leadership is very very crooked. **Recommendations to others considering CallTower:** I would look at other service providers who have a better understanding on client relations. Save yourself the headache. Look elsewhere. Especially if you are an MSP. **What problems is CallTower solving and how is that benefiting you?** Service is ok at best. Many of our clients have complained about service, calls dropping, etc... ## CallTower Discussions - [What is CallTower used for?](https://www.g2.com/discussions/what-is-calltower-used-for) - 1 comment -
