[lukass2000]

Hi,
have flashed LineageOS 17.1 on my OnePlus 3T.
Ist there any way to use VoWifi/VoLTE with LineageOS 17.1?
Thanks

Yes, there is. Do you have the settings under mobile network to enable VoLTE and VoWifi? Did you check the build.prop? Do you see the following props?
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1

If not, add them to the build.prop, reboot and try to enable the settings.

I'm running crDroid 6.5 (which is based on LOS 17.1) on my OnePlus3, and I see the settings. And it's working with the German provider Telekom.

you could have asked in LOS 17.1 thread instead of creating a new thread

@meiser have edit the build.prob and inserted the tree lines.
Now i have a button to activate VoWifi
Can activate but does not work
Thint the problem was my network operator.
On my OnePlus 6T (with OxygenOS 9.0.9) i must set to H3G Denmark profile manually with special tool, only then it did work.
So i think LineageOS can VoWifi but did not work with my network operator

Well, there're howtos to enable VoLTE/VoWifi by activating the right profile via QPST.

@meiser Have searched, but foud no info or thred to Lineageos and QPST with OP3, all is only fpr original OxygenOS
Maybe you have any URL/Link for me

It was under https://android-hubo.de/thread/7983...te-vilte-vowifi-freischalten-de-nl-ohne-root/
But the site is down.
This QPST method is independent of the used ROM, it changes the profile in the EFS partition.

Sorry, can't help you more than this.
