Open Stage 15 3rd party registration

[zhex]

Hi to all. I have found some similar topics, but all threads are closed.
I don't have any experience with Hipath, and now I need to register few Open Stage 15 HFA phones to existing Yeastar PBX system. We registered several phone brands to this existing system without any issue, hoped that the same will be with OS 15, but now I can't even approach to this phones

I see IP address of the phone but can't access to it trough network. Did factory reset.
I know that there are some brands which close ports for security reasons, can that be issue here too? I downloaded Open Stage manager V3 (only this one I found), but this software doesn't discover phones too.

I would appreciate any help.
Thanks!
