What users say about RingEX's value for money

I like the ability to video chat. Being a company of nearly 1000 people calls for a lot of meetings and we recently transitioned from LifeSize which has been nice.
That's been my experience lately, which can be a pain if I inadvertently forget to open the application when I'm supposed to be called.

What users say about 3CX's value for money

The quality of the recorded calls is amazing and it makes them very useful for training purposes. 3CX gives you a lot of freedom to organize the call list in a way that works for you.
Great integration with existing system, and helped us streamline the forwarding/holding/transferring process. VM to inbox was amazing.

What users say about ULTATEL Cloud Business Phone System's value for money

Our salesperson,[sensitive content hidden], was great. We didn't want to see demo's, so he did an amazing job outlining everything that they do and how it would benefit us and our company.
Unreliable, lost calls daily, complaining customers, HANGING APPLICATIONS, and the amount of data they will ask you for in order to be able to fix absolutely anything is insane.

The seamless integration between the VOIP handsets and mobile app has been great. Call quality has always been clear.
Works great on mobile and desktop. The call quality was overall consistently good and it did integrate with Salesforce.

What users say about Ringover's value for money

I can proudly say that my user experience is very successful. I keep a good opinion of this solution.
Integration with salesforce is good, overall quality of calls are good. There are some nifty features like note-taking and more.
