#issue9021 No, most of other submissions work fine with similar input. And in our environment I can't make it work even 1 out of 5 times

Can't manage to make tgvoipcall work on Buster. Every time ends with

Error connection timeout

Same for callee. Tcpdump shows traffic both to and from reflector.
Just tried with completely fresh install, still doesn't work.

Trying to do it manualy will ends with the same results. But in autotesting i wil make successfull cal. Do autotesting with simple python3 util.

You can run it with:
python3 ./tg_runner.py -k <api_key> -S <samples_dir> -O <output_dir>

Script dependencies:
# apt install -y python3 python3-pip
# pip3 install argparse requests uuid

With enabled debug I see this error:

W/tgvoip: Received packet has wrong key fingerprint
W/tgvoip: wrong decrypted length

Full log of such call you can see there: https://pastebin.com/DzYEJbj0

Sorry, it is mixed output from caller and callee, but there all info you needed
