5/5

What do you dislike about Ultatel?

Sometimes the system can be a bit slow or glitchy when switching between devices or managing the admin dashboard, and the interface could be more intuitive for new users. Review collected by and hosted on G2.com.

Ultatel is helping us streamline communication across multiple departments and team members, ensuring calls are routed to the right people without missed connections.

"Top Notch Service from Phone Provider, Ultatel"

5/5

What do you like best about Ultatel?

The incredible personalities and helpful nature of the team members I've dealt with from the beginning. From Alex, the Account Manager, to the onboarding team with Peter and from the start the process has been easy. There were some minor hurdles along the way but the team made me feel 100% that they were in control and had this.

The pricing is much better than we were paying.

Their dedicated non-profit structure is to be commended.

The app is awesome.

24/7 Customer Support line is a game changer!

There are a number of features we haven't signed up for, but we can already see ourselves integrating down the road. Review collected by and hosted on G2.com.

What do you dislike about Ultatel?

I have not found anything that I dislike yet. Review collected by and hosted on G2.com.

What problems is Ultatel solving and how is that benefiting you?

As our organization has grown we were looking for a phone system that could service us with up to 7 of our locations being in different areas. UltaTel's service allows us to reach our outlying drop ins and connect with the staff there easily, while also connecting donors that call the admin office and don't know the phone number of the locations in other towns, we can now just transfer them directly to the locaiton of their choice. It's made our world smaller. Review collected by and hosted on G2.com.

"This company bites off more than it can chew."

1.5/5

What do you like best about Ultatel?

Can click to dial. Can turn off click to dial for specific sites. Review collected by and hosted on G2.com.

What do you dislike about Ultatel?

Have to keep a large app open to actually use the phone system, which covers up important docs or information from other systems I use simultaneously. Constantly having connectivity issues, they tried to bully our IT team into allowing them access to proprietary information to make their jobs easier. They were not ready for such a large scale company to use them and made false promises. Integration was a nightmare. Review collected by and hosted on G2.com.

"The Best Phone System Integration for Microsoft Teams"

5/5

What do you like best about Ultatel?

What I like most about UltaTel is their excellent customer service and their desire to support the needs and resolution for the customer. Review collected by and hosted on G2.com.

What do you dislike about Ultatel?

There is nothing I dislike about UltaTel. Very happy with the phone system. Review collected by and hosted on G2.com.

What problems is Ultatel solving and how is that benefiting you?

We previously had a voip phone service that did not meet our expectations. We had extreme issues with dropped calls, static and volume. Since our primary business is at least a 75% call center environment, it is essential that our phone system is up and running at all times. Ultatel had the best solution for us. Especially since they offered the integration with Microsoft Team and the ability to use soft phones. This allowed our staff to have connection with our clients even when working remotely.

"Seamless Onboarding"

4/5

What do you like best about Ultatel?

I appreciate Ultatel's seamless onboarding process. Making the transition to their service was a breeze, thanks to their user-friendly system. It's always a plus when things just work smoothly from the start. Review collected by and hosted on G2.com.

What do you dislike about Ultatel?

There are a couple of aspects that could use improvement. The process of resolving support tickets through email proved to be inconvenient, especially during the two instances when our phone system went down. Having the ability to call for immediate assistance during such times would have been invaluable.

Additionally, the promise of complete autonomy in managing our user list and making changes was not entirely fulfilled. While we were told we could handle these changes, it turns out they require Ultatel's intervention on the back end. This dependency on their end somewhat contradicts the initial understanding of autonomy. Review collected by and hosted on G2.com.

What problems is Ultatel solving and how is that benefiting you?

Prior to Ultatel, we were in dire need of a phone system that could cater to our quality assurance needs, specifically in terms of call recording and analytics. Ultatel stepped in as the solution to this problem. Their phone system not only addressed our communication needs but also provided robust features for quality assurance.

"Solid Performance, Good Price Point, Seamless O365 Integration"

4/5

What do you like best about Ultatel?

So far the performace has been better than expected really. I had concerns with this due to not hearing much about the platform before researching. I was looking for seamless O365 integration with Teams and this does the trick perfectly. Great price point as compared to other options. Customer support is very quick to respond. Review collected by and hosted on G2.com.

What do you dislike about Ultatel?

I would say onboarding could have been a little better but probably similar to others. This was my first time converting from on prem to cloud so it is hard to compare. Review collected by and hosted on G2.com.
