CallTower

I’ve been reselling for Calltower/Appia even before the merger. The trunks are very reliable, and there’s only been a few hickups due to the ISP’s being at fault. I manage over a dozen businesses that have Calltower as their provider.

I am using just basic SIP trunking, and I handle all the PBX operations on my side.

Pricing is very good on what is delivered for the cost. I fortunately have some good reps I can deal with to get things going.

A few customers have had billing issues, such as 2 trunks that needed to be invoiced to one owner was messed up for a few months, and a trunk that needed to transfer ownership proved a huge challenge.

Once it’s set up and rolling correctly, Outages and service interruption are pretty darn rare. Getting things rolling can be a bit of an adventure, HOWEVER, the tech team always speaks English, and I don’t have to deep dive into proving that I represent the customers before we can get something done.

Tech team gets an A-
Billing Team gets a C.

We are a small company and used Appia, then calltower for over 10 years. We were very satisfied when it was Appia but then after the take over we had service issues abit infrequent. When our new owner moved us to their system the irritation started. We cancelled but they kept billing my credit card and for two months no response to my calls or emails. Finally a nice rep called me and said he’d get it fixed and did, I think, but it took two more months plus no email explaining the credits. I just let it go as amounts were small. Good luck with your service.

Calltower is becoming the go to Carrier for mid-large Not-For-Profits in the D.C. Metro. I love dealing with them. Not perfect, but the support damn near is. I give them 5 stars for any/all clients, that I work with. Calltower is great company and I have loved working with them through all levels of the sales cycle.

I have been tying to CANCEL this service for many months as the company utilizing CallTower services is no longer in service. I’ve sent many requests for cancellation of service. In one e-mail they responded if i wanted to port any of the lines to another service and I simply replied “no.” Eventually when I spoke and e-mailed back to them they said the didn’t understand what my response “No” meant. One excuse after another. Once I canceled the credit card for the account they were somehow able to “hack” into the the subaccount of my wife and charge that account. What word do i use? Fraudulent, unethical? I have not used Call Tower for many months (I moved out of my office space last year) and they continue to bill me.

I have been utilizing services from Call Tower since September 2020. FIVE STARS for an outstanding level of customer service and availableness of the team for sincere help when needed! Best part: they even follow up! Big shout out to Richard Page & Frank Rusignuolo for going above & beyond! Thanks!

CallTower offers many products and they work to find solutions to Microsoft Teams limitations. We use their paging solution with Algo devices. They have setup an Intercom solution for us as well. They have Microsoft Certified Engineers and many people working on the back-end to make sure the solutions all work together. I am very happy we went with CallTower to host our SBC.

We had a few hiccups due to unclear expectations set from the beginning, but the implementation team was organized and on top of the transition that occurred. When needed, the escalation process worked extremely well and responses were received timely. Overall, I enjoyed working with the CallTower team and would recommend their solution.

We switched from straight Microsoft with literally no support to Call Tower. They now handle all our O365 licenses and provide an in-depth level of support for both Teams Calling and O365. We attempted to mimic our old VOIP phone system and it’s operations and Call Tower was able to provide to closest match possible. Additionally they have provided a go-to for all our support issues and license needs.

Our company’s previous carrier could not connect directly to MS Teams, which is what our organization decided to use for a complete communications solution, including telephony. We decided to go with CallTower and couldn’t be happier. They were organized, and quick to port our numbers. User only noticed that call quality was better, and more stable. For an admin like me, I’m happy to no longer have to maintain on-site hardware.

We migrated from our old provider Ring Central to CallTower to move our users to Microsoft Teams calling. They put together a plan gave us the options we needed and handled the migration. During the migration we had one contact person that handled all questions and any problems that came up. After all users were converted and our numbers ported over they helped us with Teams issues that would eventually come up and gave us solutions to solve them. We have been on the service for over ten months without issue. If anyone is looking for a company to help with your voip conversions I’d say give CallTower a try at least hear what they have to offer.
