But a software developer should not make the default ON for advertising audio/video support, and default OFF for advertising audio/video support. Call-blocking is a user action. Likewise, metaphorically speaking, the "phone" should have a chance to "ring" for incoming calls from a deaf person, by default, until the user decides to opt out (i.e. intentionally put a call block on a class of calls such as fax calls, calls from deaf people, call from specific numbers, etc). Equivalently, that's why if software advertises audio/video existence, it should advertise real-time text existence via Section 5. The normal way to turn off "off" should represent "Stop sending <rtt/>, stop displaying incoming <rtt/>" ....unless there's an intentional desire to completely call-block the ability of real time text (like a user preference for blocking incoming audio and video call attempts). That's an acceptable approach to provide such a preference. But the *default* advertising setting should be equivalent for all interactive means of communications (audio, video, RTT). If all are blocked by default, it's fair. But if audio/video is enabled, then Section 5 of XEP-0301 MUST be followed. Metaphorically speaking, what I am saying, is that it should not be the phone company's responsibility to automatically block certain phone numbers -- the user should specifically choose to do that.
