Adds an extenstion to the list of supported
extensions for Invite. If an incoming Invite message has a required
header that does not exist in this list, it will be automatically
rejected with 420. Once an item is added to this list, it cannot be
removed. This list does not affect outgoing Invites for which the
application is responsible for adding any necessary headers such as
"Supported" or "Require" headers for specific SIP extensions.
