3CX iOS App Won’t Connect

[Pk2CA]

We have a 3CX hosted service with users using iOS and Android apps. My iOS 3CX will not dial or receive calls. The phone dialed shows “Connecting”. I can see other users listed, with their current status. I can access and listen to voicemail. I simply can’t make calls.

I have tried:

Power cycle iPhone
Delete 3CX app on iPhone
Reprovision 3CX app on iPhone
Software updated on iPhone to 16.3 (beta)

My business partner‘s instance of 3CX on his iPhone is working fine. Any suggestions?

Are you using a VPN?

Yes! That was it, thank you! Turned it off and the app works fine. Is there a way for the app to work with a VPN or do I just need to make sure I don’t use it?

Not yet. They're working on it.
