1 year ago I grabbed a logcat of the Pixel 6 just after turning ON the VoWifi settings and I see the following errors:

Some more details on the edpg server that it's trying to connect to:

Edit: fix formatting

Creating a new issue as I'm not sure you will see the #15 as it is closed. First of all again, thank you for your work, it really is a shame that ISP/manufacturers cannot make this work. I have a Pixel 6 with Movistar in Spain and cannot get VoWifi to work while in airplane mode and connected to wifi only, while it works when also connected to 4G/5G (not 3G as then it doesn't get IMS registration). With the same SIM on a Samsung Galaxy S10+ (Exynos version), VoWifi works perfectly while in airplane mode. Here is the carrier config of the Galaxy S10+: s10p-carrier_config.txt This was the file submitted by @combathero32: carrier_config.txt I hope with your experience you can identify where the issue might come from. I have both devices here and can help / provide any further info that you need. I'm hopeful with your help we will make it work this time.
