12. Difficulties
·∙ No signaling technology, but you still need a stun/turn server
·∙ We tried hollaclient -> nodejs dependency
·∙ We tried to use candy-jingle -> too complicated
·∙ Difficulties with ordering of signaling messages
·∙ Error handling not strong enough
12/16
13. What we liked
·∙ Web standard
·∙ Very flexible UI
·∙ you can put the video anywhere in the page

14. Future
·∙ Many other possible usages:
·∙ Click to call
·∙ Online Support
·∙ Recording audio/video or screen
·∙ Call outside of the chat application
·∙ Multi-user calls
