P2P group conversation gets created, not cloud-bas...

Question

using Skype 4.3.0.37 on Linux
newly created group conversations are P2P, not cloud-based. I kick all the participants, quit myself, recreate group conversation - and it is P2P again
how I create new group conversation:
I open chat with one of my contacts(1), then use "Add people" feature to add one more contact(2) - group conversation gets created, where there are three people - I, contact1 and contact2
I am checking conversation type using "/get name" command as its described here: https://support.skype.com/en/faq/FA10042/what-are-​chat-commands-and-roles

Answer 1

(To check if your group is P2P or Cloud based, type /get name into the chat window and press Enter.
If the group name response starts with 19:... you're in a cloud-based chat; if the group name response starts with #skypename... you're in a P2P-based chat.)
There are 2 ways to move your group chat to the Cloud.
The Fork Way
Type /fork in your old group chat. That will instantly create a new group chat with all the participants of the old chat.
The URI Way
1) Create a new group chat with a few of the people from your old chat. 2-3 will suffice.
2) In this new chat, type /set options +JOINING_ENABLED
3) Then type /get uri. You will see a link appear in your chat - that is the URI of your new group chat.
4) Paste the URI in your old chat, and tell users to jump across by clicking on it.
Note that these options work best if every person is using the latest version of Skype.
