You lost me. What do you mean we can't ignore it? the way I see it, sure we
can and we should.
Currently that warning comes from the on_ringing() callback which blindly
attempts to move the state of the zap channel to ZAP_CHANNEL_STATE_PROGRESS,
even when the state may be already ZAP_CHANNEL_STATE_PROGRESS_MEDIA (which
means on_proceed() was called first).
As I see it, the VETO warning is more an aid to the programmer so you
quickly realize your doing a useless state change, which should be fixed. In
this case, the fix is simply checking the state of the channel before trying
to move it to progress, and don't even try to move it if already in progress
