If you look in your OBi Call History, it shows Peer Name and Peer Number. All call routing, call barring etc depends on using what is shown in Peer Number. Peer Name has no effect.
In your example if the Peer Number shows as 4161422342, then adding that to the list would ban that number. Your InboundCallRoute might look something like:
{(?|x|xx|xxx|xxxx|xxxxx|xxxxxx|4161422342|un@@.|anon@@.):},{ph}
This method sends the call to the "bit-bucket". That is your OBi appears to not exist. Callers should get fast busy, "number unavailable" etc.
