Scottlindner, are you suggesting I add a dsl filter at the modem? There is none in the line at present as I'm not using dsl. I'll give it a shot. I did try disconnecting the line from the "wall" port to the scout. I also tried disconnecting all devices except the pc from the wall jacks around the house. I wonder if some kind of noise is being induced into the telephone wiring from something.

You may have hit on something Scott. I installed a spare dsl filter in the line to the pc modem, then made 4 calls to my home number, and the caller id was read immediately after the first ring on all 4 calls. I'll do some more testing, but I'm fairly confident that you have come up with a fix. Many thanks for the suggestion.

I know it sounds confusing. DSL and HPNA (the technology used to communicate with Scouts) use the same spectrum on the phone wires. So even though you don't have DSL, your Ooma is doing the same thing. Although I am confusing myself on this one. We use DSL filters so you don't get noise on phones, but why isn't that a problem with Ooma and our phones? Maybe lower power than DSL? I may have confused myself on this one, but it seems reasonable this may be related to the PC modem issue.

I'm glad it's working for you. Let it roll for a couple of weeks and post back if it continues to work.

Scott
