No you got it wrong. It means that if the extension dialed is unknow,
meaning no extension was dialed but the calles has to handled as in
the case with an FXO port that rings, since there is no way to know
what extension its trying to reach the s extension is used.
If however the extension dialed is known but doesn't exist in the
context then the i extension is used.
