Hi,
I have run flexisip sip proxy in docker image and under my wifi router, and I have setup port forwarding of 5060 only in my router. so my linphone(mobile phone) could register to my flexisip by public ip. But I cannot hear voice/video during the sip call, and it will automatically end the sip call after few second (30 second),
But everything is working fine in private ip. I think it should be firewall problem, but I have no idea how to configure it, can someone show me the flexisip.configuration?
