[Freeswitch-users] WebRTC / Voice- and/or Video-Call to freeSwitch / which JavaScript-Library should I take

Hi there, I am new to WebRTC. I just installed my first FreeSWITCH-Server (1.6.6) and SIP-Calls work fine. Now I want to implement a simple Button on our homepage to establish a voice and/or video-call with a fixed extension in our dialplan. I do *not* need a complete Sip-Client-Interface etc. I just want to implment a simple "Call-Button" :) Do you have any good suggestion, which JavaScript-Libarary I should use in that case? Thanks in advance Thorsten
