How to set up asterisk + webrtc in docker?

Question

Asterisk

Hello. No sound when talking between softphone and webrtc client if asterisk is deployed in docker. First I tried everything on a separate machine (centos) on the local network, and everything works. Maybe someone came across? Where to dig, rtp, firewall?
Asterisk configs:
http

[general]

rtp

sip

when a debug call between softphones shows something like this

Sent RTP P2P packet to 172.17.0.1:62473 (type 00, len 000160)

when between softphone and webrtc

Got  RTP packet from    172.17.0.1:56960 (type 00, seq 030790, ts 2058200046, len 000160)

Sent RTP packet to      61.176.2.13:33001 (via ICE) (type 00, seq 029385, ts 2058199880, len 000160)

61.176.2.13 - ip external (not white)

when calling docker I send

-p 5060:5060/udp 
-p 5061:5061/tcp 
-p 10000-10100:10000-10100/udp 
-p 8088:8088/tcp

Answer 1

I would try disabling STUN so that Asterisk doesn't try to send something to the external IP address.
