Uhhh, so as to the initial order of called vs. caller, it seems they're actually correct, and it was actually me being civilian and having reverse expectation; sorry!

As to the hardline related communications, I'm trying to find a good point in the recording. For now I managed to find the eventual successful contact attempt here: https://youtu.be/zNklfC6jgBs?t=10746; I'll try to rewind and find esp. the earlier Endeavour responses & the Russian responses.

edit: Ok, here's some early fun with Russians: https://youtu.be/zNklfC6jgBs?t=6085, not yet sure if that's the 1st one but definitively a sample of what I meant. Still looking for more. edit 2: A bit more just seconds later: https://youtu.be/zNklfC6jgBs?t=6616

If you check SpaceX's stream on YouTube, they check the hardline communications with the Dragon capsule multiple times in the hour or so after hard capture.
