Dear, client.
This is Yukai, a senior web developer, especially WebRTC/web conference system expert.
I have good experience in jitsi-web version and jitsi -app version.
JITSI contains VoIP, videoconferencing and instant messaging applications for the web platform and I am confident.
I can help you integrate jitsi to your own site.
I want to discuss more in detail.
Thanks.
