[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.

For WebRTC, I recommend you to use Asterisk 13+.

Have a nice day.

Hello

then why is there an option in sip.conf and rtp.conf " icesupport=yes"
??

This is no answer to my question.

So again : what am I missing to get ICE support on my Asterisk 11.23.0 ??

Kind regards.
