All new phones that are built in China by 3rd party factories are garbage compared to the old days where phones were dependable and well constructed. It doesn't matter who the manufacture is. Cheap electronics fail often.
Yes. I tried two different phones and neither one worked in "Tone" mode. I had a dial tone but they neither phone would dial out. When I switched the phones to "Pulse" mode they both were able to dial out. I thought maybe the modem needed to be switched from Pulse to Tone but I don't think that is the case. I guess I will keep buying phones until I find one that works and return the rest.
