Hello,
We are seeing issues with the 3CX app not registering when on the IPv6 T-Mobile cellular network. I know a lot of work has been done on this already, but for us it is not working. Our 3CX server is hosted externally.
When an iOS device is on a Wi-Fi connection, the 3CX app works fine. When we are on T-Mobile LTE / 4G, the presence is detected, but the SIP registration fails. If I connect an iOS device to another iOS device via Personal Hotspot, the IPv6 symbol in the app does not appear, and the SIP registration is successful. It's only an issue when IPv6 is detected.
Our 3CX server does not have an IPv6 address, and we have no IPv6 information in any of our DNS records.
Not sure if other people are seeing this issue or not, and if anyone from 3CX is able to troubleshoot?
I don't have access to devices that are not on T-Mobile, so I am unable to test if the issue occurs on Verizon, AT&T etc.
Our 3CX server is running 15.0.62928.5 and the iOS app is 15.2.6.194.
