I have 2 Ooma systems at 2 different locations. I tried Murphy's test and called from 1 ooma system to the other ooma system and tried the tone on each end. On the calling phone I hear a click and on the called phone they hear a garbled scratching sound. No tones on either one.Does anyone, that knows someone else with an ooma system, want to run the test? Place a call to the other system. Press a button and ask if the person at the other end heard hears the touchtone normally. Then have them push a button and do you hear the touchtone normally. This will determine if it is an ooma problem or a PSTN problem.
I no nothing about the technical side but hopefully this will provide some good information for the tech crowd.
