When SIP user agents or WebRTC endpoints are deployed behind such firewalls, media cannot be sent over UDP across the firewall, but must be sent using TCP (which causes a different user experience) or through a session border controller. This draft describes an alternate model wherein extensions to ICE connectivity checks can be examined by the firewall to permit outgoing UDP flows across the firewall.}, }
