Simply does not work - at all

Mobile telephone user

I have spent months tring to make this app work with expense of IT tech assistance and upgrades. It worked sporadically on I-Phone before 10 iOS. Absolutley does not work at all since then no matter how much time you invest in it. It will, however, dial your party, sometimes connect, and then they will be frustrated in that they cannot hear your voice. Great way to aggravate your customers. Even before it stopped working at completely after "I-Phone 10 IOS, " really too sporadic of performance to rely on in business. Forget this one.

Great app but lacking a few features


It is a nice and functional app for what it does it does well. I would like a little more flexibility. Like changing the ringtone for example. The call recording is also hit or miss, sometimes static background noise and large file sizes. If they add custom ringtones and improve call recording quality I will rate it 5 stars

Quite improved


Used it for 3 years with UcallWeconn. Current version is quite improved - no drops and nice quality.
