Asterisk for Docker GitHub sites https://github.com/christoofar/asterisk   https://github.com/mlan/docker-asterisk   https://github.com/azielke/docker-asterisk   RTP ports and Docker Way 1 Docker cannot deal with a wide range of UDP ports being forwarded. One way to get around this is to run the container on a machine that is not using 10000-20000 UDP and start the container with  --network=host . The downside is that a container stated in this way cannot communicate on any of the docker networks. Way 2 編輯 rtp.conf 將預設的 RTP Port 號範圍做修改。 有些 trunk providers 可能可以支援這個埠號範圍 rpt.conf [general] rtpstart = 10000 rtpend = 10099
