I have a voice orb on my website and I keep getting attacked and its running up minutes, two days ago it happened and they ran up 8700 minutes on 867 calls 10 minute max duration, so i lowered that to 5 minutes, put BotID in place and tighted thigns up, but they still got me for 800 minutes today. it cost me $4000 the other day and $500 today, what else should I be doing to prevent this? I still want to have my demo on my webiste....
