XX-10711 - configure Polycoms running 4.0+ to be able to use TLS.
Admins will have to set registration server transport to TLS and if it is the case outbound proxy transport to TLS. Port should stay to 0.
This issue creates the config that will allow TLS. The configuration options are not available via sipXconfig UI.
This issue also fixes some uinit tests and adds a lot more.
