User unable to receive calls on android

[Adrian-Blue]

Hi,

We have a user that is unable to receive calls on the 3CX app for Android. The phone is a Samsung Galaxy S23. The device is up to date with Android updates. Push notifications are enabled. The only way to get the app to work is to go into the app settings on the phone and delete all the data and clear the cache. This seems to only be a temporary fix as the issue returns after a while. We have not had any other users report issue. This user has been using this device for a while and it was working fine. The issue only started a couple of weeks ago. Any help would be appreciated.

Kindly note that everyone in a particular organization (Android and iOS users) are having the incoming call issue on the 3CX App, outgoing is working though.
In terms of NAT Rules on the Firewall, everything was set as per https://www.3cx.com/docs/manual/firewall-router-configuration/

Can you please help me on this issue.

Thanks in advance.
