QuoteThe line light turns on when receiving calls but not when calling from the phone connected to the OBI.
With no calls taking place, the line LED should be on, showing that the line is connected and ready for use.
For now leave the PSTN as your Primary Line - this is the default setting.
What happens if you dial # from the handset? You should hear PSTN dial tone. If so try dialling a number. This test bypasses the internal OBi110 digit maps and call routing.
What happens if you dial **9 222 222 222 ? This should connect you to the Obihai echo test. Your own voice should be echoed back to you.
