### 1/5 — Unreliable

*2025-03-28*

I want to like the app. I really do. But it fails me each time I need to use it. The amount of phone restarts and redownloads of the app I need to do before I can make a successful call is certainly a challenge and very time consuming. It’s simply not reliable.

### 2/5 — Bad connection

*2022-11-16*

The app is a great idea. However, the constant connection issues create inconsistent ability to use the app as intended.

### 1/5 — Just doesn’t work

*2022-08-22, version 1.3.7*

We have this for work. It worked for a short while and in fairness, was okay. It has since stopped working on my phone; despite uninstalling, reinstalling and reviewing all logins. Now it no longer connects at all. Not sure if it’s worse with Apple products?!

### 1/5 — Terrible

*2021-11-04, version 1.3.7*

Feels 10 years old or more. I’ve had it for weeks and still can’t receive calls. No address book functionality. Just horrible.

### 3/5 — Unable to play voicemail on IOS14

*2021-05-04, version 1.3.7*

Unable to play voicemail from visual voicemail tab, on the latest IOS 14 update. Please look into fixing this 

Rest of the application is simple and easy to use

### 1/5 — Doesn’t even logon.

*2021-03-29, version 1.3.7*

Don’t waste your time. Commanders sold us a phone system because we wanted this app. We haven’t been able to LOGON let alone use it.... 

Definitely sold the dream but got a dud.

### 2/5 — Drains battery

*2021-01-27, version 1.3.7*

Using it for work - functional. However it overrides the iOS background refresh limitation and drains all of my battery in <3hrs. Have to keep uninstalling, as it ignores even battery saver mode.

### 1/5 — Terribile!

*2020-02-22, version 1.3.7*

Non si può lavorare! Anche se la connessione è stabile dopo 2 minuti di conversazione l’app non riceve più! Non si può, veramente! E non solo, il centralino rimane offline anche se la connessione o il Wi-Fi funzionano.

### 1/5 — iPhone XS Max 13.3.1 no volume on calls

*2020-02-03*

iPhone XS Max 13.3.1 no volume on calls

### 1/5 — Needs updating

*2019-09-05, version 1.3.7*

No longer works - please update
