You can only get one IP address from a residential cable modem unless you pay for more than one.
A switch after a cable modem is not going to work.

Thanks Murphy, I believe you are right. I think it worked last time but now that I think of it that was many years ago and I was using Internet Connection Sharing,

I also since discovered that my router is fine. It's actually the modem which has a bad Transmit Signal power level. Tech visit scheduled for tomorrow. Thanks again!

I've had our Ooma Telo behind a switch for the past 3 years and it works flawlessly.

Our connection path is:
--- Cable Modem
--- Wireless Router
--- 5-port switch connected to wireless router
--- Ooma Telo connected to one port on the 5-port switch

Good luck!

He was talking about

modem -- switch -- Ooma
..................... -- computer

That doesn't work.

Please explain a little more...

I had my ooma setup like this: Modem -> Router -> ooma for years without problems.

Now I want to move my wireless router (due to other variables such as baby get's the study kind of thing)

So I thought I could do this: Modem -> Switch -> ooma also Modem -> Switch -> Router
This allows me to run a longer line to the router.

Router works fine, ooma does not connect. I can plug my computer into the internet line and get internet but ooma can't connect for some reason.

Someone mentioned IP addresses, why would I get the router to work fine but not ooma behind a switch? Also, if I connect ooma behind the router (Modem -> Switch -> Router -> ooma) then it connects just fine... why would the router after the switch fix the problem.

I don't know much about networking so please go easy and explain as much as possible. Thanks! :D
