User reviews

Disappointing missing basic call blocking feature

For a company as established and widely used as 3CX, it is very disappointing that the mobile app does not appear to offer a simple option to block unwanted callers. Spam calls are a daily issue for many users, and call blocking is a basic feature most phone apps already provide.

The app may work for business calling, but not having an easy way to block spam numbers makes the user experience frustrating. This is something 3CX should prioritize and add as a standard feature.

Inconsistent

Sometimes it rings to my phone, sometimes it doesn’t. Sometimes I get a notification and no ring. Sometimes when I click on the notification, the app opens but I can’t answer the call. Just a poor experience overall.

No funciona

Tengo la versión online pero ahí no me entran llamadas, solo salen, descargué la app pero no me deja conectarme con el codigo QR, se queda congelado

After update it doesn’t work

It was working before, I could able to get the calls now i can see the incoming call but cannot response it %90

So unreliable

Terrible how is that they can’t fix this problem. Missing and not receiving phone calls How is this still in business
