[asterisk-users] Asterisk 11.23.0 on CentOS6 : how to get ICE support ?
Hello I'm trying for several days now to get ICE support for my Asterisk 11.23 on CentOS 6. My call setup : sipml5_webRTC (nat) --> public Asterisk on 178.18.90.230 --> softphone Zoiper (problem : no audio) Reverse does not work either. (problem : failed get local SDP) I followed this guide : https://wiki.asterisk.org/wiki/display/AST/WebRTC+tutorial+using+SIPML5 https://wiki.asterisk.org/wiki/display/AST/Asterisk+WebRTC+Support I researched on the web and found this useful thread : http://forums.digium.com/viewtopic.php?f=1&t=90167 This is no question "what is wrong ?". I know what is wrong : I need ICE support ! So the question here is : how to get ICE support in my Asterisk ? I've compiled asterisk as follow : [root at myserver admin]# yum install uuid-devel libuuid-devel [root at myserver admin]# ./configure --libdir=/usr/lib64 [root at myserver admin]# make menuselect [root at myserver admin]# make && make install In my sip.conf I have : icesupport = yes In my rtp.conf I have : icesupport=yes stunaddr=stun.l.google.com:19302 My SIP peer definition for webRTC client (sipml5) : [770000wrtc] type=peer host=dynamic username=770000wrtc defaultuser=770000wrtc fromuser=770000wrtc secret=987654 disallow=all allow=alaw ;allow=gsm qualify=yes canreinvite=no dtmfmode=rfc2833 amaflags=billing context=testwebrtc nat=force_rport,comedia transport=udp,ws,wss encryption=yes avpf=yes force_avp=yes icesupport=yes directmedia=no dtlsenable=yes dtlsverify=fingerprint dtlscertfile=/etc/asterisk/keys/asterisk.pem dtlscafile=/etc/asterisk/keys/ca.crt dtlssetup=actpass SIP registration works fine : [Aug 9 22:12:00] == WebSocket connection from '178.119.146.190:36940' for protocol 'sip' accepted using version '13' [Aug 9 22:12:00] -- Registered SIP '770000wrtc' at 178.119.146.190:36940 [Aug 9 22:12:00] > Saved useragent "IM-client/OMA1.0 sipML5-v1.2016.03.04" for peer 770000wrtc But when I call from my webRTc client (sipml5 website demo) I have no audio. I think this is because there is no ICE support. You can see in de SIP trace below and the RTP trace below that there is no ICE support in Asterisk.
