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.

What’s New

Version 15.5.18

Full redesign of 3CX Chat. It’s look is now more messenger like.
“Chat” is now called “Messages”
Added an unread message counter.
Moved the “More” menu and replaced it with a slide-in navigation button located at the top left of the app.
Where the “More” menu previously was, “Messages” for easier access to 3CX Chat.
Added the ability to tap your avatar in the options menu to quickly navigate to the “Accounts” page.
Updated PJSIP to a newer version for much better IPV6 support.
The keypad is no longer useable if the network state is “No network”.
“Schedule Conference” is now called “Conference”
Reordered several of the list items in the options menu.
“QR Provisioning” has now been renamed to “Scan QR Code”
Fixed issues related to TLS and no audio in a certain networking condition. (The fix has a server side dependency and so it will be available in the post SP6 3CX PBX Update)
Fixed several issues related to IPV6 when used with various transport modes.
Removed the “i” help icon from all menus.

Voiceover Accessibility Problems!

Update December 7, 2018.
I utilized the services of a sighted agent at Aira, installed Teamviewer on my iPhone and opened 3CX. The agent was able to tell me that there is a "Hamberger" shaped icon at the top left. THis Button is skipped when using Voiceover navigation. However I turned VO off and through trial and error was able to tap on the icon. The agent confirmed that the settings dialog came up.
After turning on VoiceOver I was able to access the items in the settings dialog.

I have not done exaustive testing.
Hoever much of the app is accessible and would be very accessible if care was taken to apply VoiceOver labeling to the buttons.
Since there is a builtin accessibility API and the 3CX app appears to already comply with many VoiceOver accessibility standards, it shouldn't be a huge undertaking to make this app into afully accessible solution.
THis would be a great help to Blind persons, since we would then be able to partisipate easily in any function available on the 3CX client.

In attempting to use the 3CX app with VoiceOver accessibility, I find the following problems.
* There is no "more" tab that is accessible. This means that I cannot use any settings options.
* The messages tab is useless because there is no accessible send button that will permit one to send text after the line has been entered.
* The buttons to the left and right of the call button are unlabeled.
* The keypad requires a double tap in Voiceover in order to enter a number.
It appears that some care has been taken to make portions of the app accessible. However, inadequate testing, and omission of accessibility in key sections of the app make the usage very difficult, and in some cases including chatting, impossible!

Great when it works, but it’s horribly unreliable

I really want to love this app, but I can’t. When it works, it works great! The problem is that it’s just not reliable. I use this app only when I’m in my office with my iPhone connected to my office’s wi-fi. Frequently (but not always) when my iPhone is connected to my AirPods and I launch it and make a call, the call connects and I can hear the recipient, but the recipient cannot hear me. When I click the speaker button on the “in-call” screen, it says it’s connected to the AirPods, yet the recipient can’t hear me. And it’s not just with Apple’s Bluetooth AirPods. This also frequently happens with Apple’s wired EarPods. In addition, I can never successfully make 2 calls in a row without having to force the program closed. The first call connects, but the second call doesn’t. Basically, I have to force-close the app after every single call. Occasionally even a force-close doesn’t help either and I end up having to reboot the phone for the app to start working again. This is all on a brand-new iPhone XS Max running iOS 12.1. I had the same results with my previous iPhone 8+.

Works ok

I’ve replaced my desk phone with this app and it’s been quite an experience.
App has no support for Shared Parking buttons.(had to create contacts for each shared parking slot and have to call one of them to grab a call, or transfer a call to it)
The IM feature is practically hidden. (Personally think the IM should be it’s own app)
Sometimes I answer calls and have no audio have to hang up and call back.
The android version of this app is completely unreliable and only actually rings maybe 30% of the time.
If you go on their forum and give any type of feedback that doesn’t involve overwhelming praise they will ban you.
