Additional Information

Based on past issues, I tried to identify and solve the problem myself, but unfortunately without success. In the filtering list, I found the following server address: epdg.epc.mnc097.mcc466.pub.3gppnetwork.org and added its IP 175.96.62.1 to the ignore list in advanced settings. However, WiFi calling still does not work properly.

@zongh4n Nicely done! Try to add the 175.96.62.1/32 line to the pref.ipv4.routes.excluded list in the Advanced -> Low-level

More details about the issue and solution in #2550

@Versty Thanks for quick reply! after above steps and check #2550 and more other comment, specifically comment of @elween07 steps, now working well. even I turn on airplane mode, can still receive calls very quickly.
