Can't make video calls without internet (Wifi hotspot)

Steps to reproduce:

You are using two Android phones with the same Jami account (device 1 (sameuseraccount) - device 2 (sameuseraccount)).

Now you disable all internet connections (on all devices; wifi and/or LTE)

1. Now use device 1 to create a Wi-Fi hotspot
2. Now device 2 will use the same Wi-Fi hotspot like device 1 (and will warn you that there is no internet)
3. If you tap a contact ONLY device 1 will show "no network connection" (NOT device 2 although it uses the same hotspot (without internet))

• You can send messages (haven't tried attachments) but at first you'll have to wait like 30 seconds or a minute (even if you're already connected to the WiFi)

• If you switch- so that device 2 no creates a hotspot even text messaging won't work anymore?

• But you can never make any calls (Desktop (hotspot WITH internet?) - Android had no issues?)

changed the description

I guess DHT status is disconnected. I have never seen any android phone which its hotspot supports multicast (Local peer discovery is not working).

If you know the DHT port (hard for android) , you can paste ip:port pair to "Bootstrap" (separated by ;) and disable DHT proxy.

Sorry. Previous opinion is incorrect, I have re-tested with three android devices(device 1 is hotspot), device 2 and device 3 can make calls. @El4

yeah hotspot will certainly not support multicast. you will have to bootstrap one account on the other one and also disable push notifications
