[SIP Beyond VoIP] Sylkserver Setup without a SIP proxy

[Tijmen de Mes]

Hi,

Thanks for the kind words about SylkServer/Sylk-webrtc.

I suspect is has to do with the chat feature that was added. For this, the webrtc application connects to the ‘normal’ conference application. 

Is the conference application in SylkServer enabled? If it is not, you probably need to enable it and make it available on conference.yourdomain.at <http://conference.yourdomain.at/>. It is probably also a good idea to limit access to the conference application by adding some firewall rules. The only service that will connect to it will be SylkServer itself.

Best regards,

Tijmen de Mes
