For interested 3CX iOS client users, some useful good news: it seems now iOS properly allow 3CX client to be invoked from other applications to call phone numbers: just long-press the number and the iOS will display a popup menu where 3CX client is now also present (attached screenshots img_0129 is from Notes app. img_0130 is from Mail app). Now, the bad news: - it seems the menu shown in browsers doesn't contain the 3CX client (we tried with Safari and Chrome); however, neither Viber (we tried it as another softphone) is shown. We'll have to dig to see why (maybe's a security precaution taken by Apple). - if you try with released, AppStore's 3CX client (15.2.11) it may not work first time when 3CX client is launched - it should have been in the background already. However, this issue is fixed and will be available starting with 126.96.36.1992.
