Hi Thanks for the insight. When I did do #38 it also showed n - not available I believe on ports 7 & 8. That was when the line was hooked up to both cordless and regular single line house phone. I will have to check again. There are no added boards on this model or secondary add-on boards . Is this #38 required for Single line phone to get a dial tone on the line ? Just thought I would ask .

Thanks again
