### 1/5 — Issues

*2026-06-24, version 3.6.0*

Why am I unable to delete a contact…..seems to always have a “Something is wrong..” message pop up when trying to make an outgoing call. Beginning to fall under a useless category of apps.

### 5/5 — Great App

*2026-06-03, version 3.6.0*

It works great when I am home and have my WiFi connected and it works great when my cell phone signal has two bars or more.   Obviously if WiFi or cell signal has issues, it will disconnect but in LA we have great cell service when away from my home WiFi .

### 1/5 — Error messages galore

*2026-02-19, version 3.6.0*

Unfortunately I’m unable to use it for work. Continuously getting error messages of not being able to access or connect to make calls.

### 1/5 — Randomly won’t let you make calls

*2026-01-28, version 3.6.0*

I don’t know what triggers it, but randomly you can’t make calls out. It just sits there “Connecting…” forever and ever. Logging out / back in and rebooting rarely works. You just wait it out or use your cell phone itself, looking unprofessional.

### 1/5 — This app sucks not user-friendly

*2026-01-20, version 3.6.0*

This app sucks. First off. I have to click the hangup button on iPhone three different times before it. It’ll actually disconnect.

Secondly, they do updates to their system and don’t tell the provider who is contracted with them, which is not me and if the provider is not notified, then the customer is not notified

The update that they did I am not able to access video recording at all the provider I have that is contracted with this company Informed me that not even their tech support knew.

### 5/5 — Cloud Phone System User

*2025-11-06, version 3.6.0*

The app is a very helpful tool to supplement my office phone keeping me connected to my business anywhere.

### 2/5 — IOS device heats up when making phone calls.

*2025-08-24, version 3.6.0*

My IOS device heats up when making calls. My associates have an android and it works fine. My clients that I uploaded only show up on the phone app. They do not load using the web version. App Needs help, app works great for changing my voicemail. I cannot make calls.

### 1/5 — Horrendous

*2025-08-08, version 3.5.20*

Calls drop constantly and they have no willingness to improve the quality.

### 1/5 — Terrible

*2025-06-27, version 3.5.20*

Calls drop or can not hear. My company currently uses this but wish they didn’t.

### 3/5 — Call button

*2025-06-13, version 3.5.20*

Maybe nudge the call button up a tad? Away from the bottom bar just a bit.
