A SIP phone connecting to a server using TLS with no client cert needs to be able to receive outbound messages on the same connection. Currently it doesn't work since the server can't verify the TLS connection properties with the content of the contact URI.
SIP over web socket solves this by using a "half outbound" with a useless contact URI.
