I changed DNS (8.8.8.8 and 9.9.9.9) and restarted my OBi 200 but still doesn't work. No incoming or outgoing calls. Dashboard says "Connect Failed: No Response"
I see some host names in the configuration. Should I be able to ping
obihai.sip.google.com and/or
obihai.telephony.goog ? For both of those I get "Ping request could not find host". But some servers don't respond to pings.
Are there some OBi troubleshooting steps I do by dialing codes on that phone? I set his box up years ago and don't remember much about it.
