How to fix T-Mobile Wi-Fi calling issues on P5

Recently, we have received feedback that the Wi-Fi calling cannot work normally when the Phone connects to P5's network.

Here is a beta firmware that may solve the issue temporarily.

 

How to process?

Step 1: Access the web management page and upgrade the beta firmware below.

Step 2: Go to General Settings->Cellular->APN. You can see a 'T-Mobile wifi-calling' button, choose 'ON', then Save & Apply.

 

 

Step 3: Reboot the P5 and the phone at the same time, then check if the Wi-Fi calling works or not.

 

Any feedback would be appreciated!
