I'm glad the Internet Root Name Servers don't use OBIHAI's business model of NO SUPPORT, NO 24 Hour On Call Server Support, NO automated Server/Services Monitoring or the Internet Would just break, just like OBIHAIs SHIT service.
Seems if you have InboundCallRoute set to another OBI ATA via pp(000000000) the call never goes anywhere, even if you also have the CallForwardOnNoAnswerNumber set to forward when Obi Service is Off-line.
This business model in just pure negligence.
