Karsten, I executed the openssl commands   against my local server and webrtc.freeswitch.org,  both show the same output that you described against a broken host.

Using Firefox I still have the same results:

Firefox -> 5000 ->  webrtc.freeswitch.org ....... GOOD
Firefox -> 5000 -> my local vm .......................NO AUDIO

And now using Chrome:

Chrome  -> 5000 -> webrtc.freeswitch.org ....... NO AUDIO This worked before
Chrome ->  -> 5000 -> my local vm ......................GOOD
I am using Chrome 29.0.1547.57 m

Karsten, did the suggestions from Anthony work for you?

Anthony, In the freeswitch cli I see this message many times
2013-08-22 11:42:55.504980 [ALERT] switch_rtp.c:5662 Skip sending audio packet 98 bytes (dtls not ready!)
Do you have something related to dtls configured in webrtc.freeswitch.org?

Your example might have different network conditions than the demo.
You can check by enabling sip trace on FS and bring up the call and look at the ports that are advertised out.
You can try turning off selinux or iptables as a test.

Hi Anthony,

how is the best way to check that? With wireshark most stuff is ssl unlike normal UDP/SIP stuff.

Iam still confused, that it works with webrtc.freeswitch.org at work and at home, but not with my example setup.

I checked for iptables (everything fine), and its no cloud virtual foo where the server is running.

Thanks in advance,
Regards

Make sure its going to the ports that are advertised in the sdp and that there are no nat or firewall issues in between.
