As other DC clients, DeltaTouch v2.220 comes with experimental calls support. To test the new call feature, go to Settings → Advanced, enable “Experimental Features” and then “Debug calls”. You will then see a new 📞 button in the header of 1:1 (direct/private) chats, click there to start calling!

NOTE 1: It is a know issue that outgoing video from Ubuntu Touch devices does not work at the moment, and incoming video only works sometimes. Please report if audio is not working though.

NOTE 2: report your experience using different networks etc. did you manage to establish the p2p call or was not possible? tests using mobile data are appreciated, but may consume a lot of data as not yet optimized

I have tested it with my [Xiaomi Mi A2]  
([Xiaomi Mi A2 (Mi 6X) - Full phone specifications](https://www.gsmarena.com/xiaomi_mi_a2_(mi_6x)-9140.php)) - ubuntu touch 20.04  
and it is working 🙂

I have tested with fresh install from OpenStore.

I have tested these:

- ✅ voice going & comming 🙂
- ✅ same network call works
- ✅ if call comming from android the video also works
- ✅ call ring (notification) works

I have tested it with android 14 device

Just to be sure, you are trying to establish calls between

- DeltaTouch and /e/OS
- DeltaTouch and Android 13  
?

Ah, so you’re using the Android app, right? This thread is about the client DeltaTouch. Maybe you can head over there: [Help testing upcoming Delta Chat release with calls 📞! - #45 by user.123](https://support.delta.chat/t/help-testing-upcoming-delta-chat-release-with-calls/4220/45)
