The 3CX client for iOS only works with 3CX Phone System v15.5. It will not work with other commercial or open-source PBXs.

This app allows you to make and receive office calls on your device from anywhere. The app fully supports PUSH, allowing your device to be on standby when not in use and save battery life. When an incoming call occurs on your office extension, your device will 'wake up' and notify you as it would with a regular GSM call.

Benefits include:

- Make and receive calls on your smartphone/tablet from your office extension.
- One number concept. Calls made to your office extension will ring on your iOS device.
- Reduced mobile phone bill; call colleagues via the 3CX client rather than via the mobile network.
- Seamless out of office or in office detection.
- Transfer & Hold calls.
- Easily change your status (available, busy etc.).
- Take multiple calls simultaneously.
- View the status of your colleagues.
- Easily setup conference calls.
- Instant Corporate Chat.

The 3CX client requires Apple PUSH to be configured by your organization's PBX administrator.

Great Phone System (PBX)

Tomorrow's forecast

Excellent phone system for micro business up to enterprise. The app is a good complimentary product to accommodate people on-the-move. The call quality is well improved and definitely gets the communication job done! Packed with features to handle inbound calls to your liking. I use Flowroute as my "phone lines" provider IPpbxHost to host my 3CX system and the whole solution has cut my phone costs by approximately 60%. Our system serves 3 offices and multiple remote workers. Works great!

Doesn’t always work right

Sonic SA

Hi, been using the app for a while now. Made life great when going out of the country.

Couple of points to fix:
1. Drains the battery very fast
2. First calls received when the app isn’t open doesn’t work. I always have to open the app after the first call and then from there on further it seems to be fine
3. Calls get scrambled and delayed once someone else phones you or if you receive WhatsApp message
4. Can’t change the ringtones and that one ringtone is getting irritating
5. Spam call Apps don't work through the app
6. Blocked numbers can get through
7. International dialing codes in saved phonebook numbers needs to be changed (eg. +27 must be changed to 0 for the number to work)

If some of these points are looked at, I will definitely change my rating.

Developer Response

Please try latest 15.5.13 - push support, call handling and background functionality has been heavily revised and improved and ringtone support has been added.

Great Softphone


The 3CX softphone app works very well on wifi, LTE, and 3G. It's a great way for me to take business calls on my mobile phone without having to set up forwarding or hand out my personal cell phone number. The call quality is great, and the calls are reliable. I can't say enough good stuff about the 3CX server and this iOS app.
