No audio from phone

Installed jitsi-meet+jigasi from docker hub images. Default configuration with jwt authorization enabled. Everything works well, but those invited to the conference over the phone cannot be heard, they hear only the conference participants from the computer. Removed docker, installed jitsi+jigasi from stable debian-packages and configured jigasi to the same sip-account, also with minimal configuration changes, everything works fine, but could not configure jwt-authorization. I would like to stay on a variant with docker, but it is not clear why the sound is in one direction. Maybe there is a problem with the docker network stack?
