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

Doesn’t ring

Notification still comes in but ringer stopped.

Verizon Wireless

I installed the app on my Verizon Wireless iPhone scanned the QR code and it worked. Left work, went to call a client and the app just says connecting. I get home and it works. I realized it only works while on WiFi. It then says I’m blacklisted. Reached out to IT and they added my cell phone IP to the whitelist. It still says IP is blacklisted…. Any support to get it working on the Verizon Wireless network and not only on WiFi?

Unable to Scan QR Code

For some reason when trying to scan a QR code the camera stays in black. After deleting and reinstalling the app it still does the same thing. I am using an iPhone 15 Pro Max.

Efficace

Super outil collaboratif

Lautsprecher extrem Leise

Am iPhone ist das Freisprechen extrem Leise geworden. Bitte wieder nachbessern. Schnelle Reaktion. Jetzt wieder alles gut.

rings constantly

I have a problem with the app. When they call me and I pick up from the staff phone, the mobile continues to ring until I close the app.

Verybad

Ứng dụng cực kỳ tệ. Chậm. Gửi file thì hạn chế nhưng lỗi file liên tục. Tìm lại tn cũ khó khăn. Một ứng dụng không bao giờ nên xài

Speakerphone Not Working

I previously had no issues till this latest update. Now my speakerphone isn’t working and everyone is hearing an echo from me. Please fix the bug! This app helped me work remotely seamlessly.

Speakerphone

With this most recent update the speakerphone no longer works, and creates an echo for the person on the other side.

Bad app

The app is now blocking me to access my contacts, chats, everything. At least, I can receive calls.

I reinstalled the app and you can only log in by scanning a QR code. Unfortunately, I only get a 403 errors and it doesn’t work.

Where is the support?

This APP is pure garbage.

Update: this app doesn’t work because of my VPN. Still very bad.

Works great and developers keep improving it

I think a lot of negative reviews are old or are problems that are not actually the fault of the app. Development was slow for a while but it’s now fully up to date including Watch support, CarPlay, etc.

Une catastrophe

Depuis la dernière mise à jour il est impossible de se servir de cette application avec le son des hauts parleurs de l’iPhone. Ça ne marche tout simplement pas. Je n’aurai jamais du faire cette mise à jour…….

Car play

No funciona

Needs work

Phone calls at times do not come in the first time of the day. I also have the ringtone set to silence and it still blasts the ringtone loud in my ears with the AirPods.

Worst app ever

Useless
