pub const CHANNEL_QUIESCED_CODE: u16 = 0x0102;Expand description
The named channel is on the roster but quiesced; the reason it was quiesced travels in the refusal’s message, not in this code.
Reserved in the server-layer band (0x0100–0x01FF). It is a distinct code
rather than a reuse of CHANNEL_NOT_REGISTERED_CODE because the two say
opposite things about the roster, and rather than a fallback to 0xFFFF
because a quiesced channel would then be indistinguishable from an internal
fault.
