3CX IOS Support v16 Mandatory Upgrade as of 04/21/2020

We will be rolling out v16 Update 5 tomorrow. It is very important that you get your installs updated to this latest version asap because iOS app users will experience failures if on outdated versions. This is because our iOS app will be using Apple’s new PUSH infrastructure.

New iOS App Requires Update 5. Upgrade to v16 Now.
Preparing for Update 5 is especially critical now, as the new iOS app will no longer work with 3CX v15.5, or any updates prior to this one. Furthermore, v15.5 is reaching EoL (End of Life) status and will no longer receive updates or support. Note that v16 Update 5 is not compatible with any Windows version below 10 or Server 2016, due to the new Apple Push Notification service (APNs) requirements.

The old iOS App will remain the default app for a month following the release of update 5, to give you time to upgrade.
