I have configured kamailio to work as webrtc server and it forwards= the registration to asterisk. Now when I am trying call from jssip webrtc cl= ient it reaches kamailio and route it through private interface to asterisk s= erver. Asterisk then route it to the provider server. When i make a call aste= risk server recives rtp from the provider and convert the rtp to srtp and sen= ding back to kamailio. but there is no sound for webrtc from public internet = . Also i am getting warning (SRTCP /RTP output wanted, but no crypto suite wa= s negotiated) webrtc from Local network works fine with VPN For normal udp call without webrtc works fine. Kamailio having two interfaces, interface1 is private 10.13.1.140 and interfa= ce 2 is publi ip 100.x.x.x webrtc client sends calls to the public ip interface 100.x.x.x and kamaiio ro= utes the call to the asterisk via private interface 10.13.1.140. asterisk server sends the call to remote server and gets the rtp back from th= at Asterisk server ---converts RTP to SRTP and forward to ----> kamailio 10.13.1= .140 but there is nothing happens after that, please help me on this i am new to k= amailio and rtpengine. The issue is only for webrtc from public internet. But when using webrtc from= LAN works fine below are the logs Mar 9 20:21:02 debian /usr/local/sbin/kamailio[11778]: INFO:
