### 4/5 — Still learning

*2024-02-08*

Love this app, canceled ring central

### 1/5 — Inbound calls / no registration

*2024-02-02*

After using this app for several years it was the best app reliable for inbound calls without having to leave the app open in the background on iOS. Within the last week or so I noticed I wasn't getting calls. It's no longer registering on my pbx. And I figured it was an account issue so I deleted my account and went back to sign up and the sign up was gone. So I think this app is now dead.

### 5/5 — Great interconnected system!

*2023-10-24*

Works flawlessly on ios, android, and windows, or from any browser. Ties all your devices and voip together. Have to register using their online server and bit of a learning curve to figure it all out. Online tutorial and help leads you the way.

### 3/5 — DTMF Tones

*2022-09-17, version 1.21*

Need the ability to send DTMF tones during a call. Nothing in your user guide addresses this widely and commonly used feature. How can I access features on the calling line if I can’t even send a “1” for English? How can I leave voice messages if I can’t send a “#” to complete? Please add this feature as soon as possible, thanks

### 1/5 — Works nice for iphone, complete broken for android
