3.1.4.8.2 Connectivity Checks Phase

An application triggers the start of the connectivity checks phase after the completion of the offer and answer exchange of candidates, as specified in sections 3.1.4.2, 3.1.4.3, and 3.1.4.4. The connectivity checks phase MUST have an overall worst case timeout, as specified in section 3.1.6.2. When a connectivity check request and a connectivity check response packet have been received from the peer, the timeout for the connectivity check MUST be reduced to the value specified in section 3.1.6.2.
