Any advise here? Thanks all in advance.
In your case your cable modem has a backup battery so you can't turn it off. Disconnect whatever is currently connected to the cable modem's LAN port. Look on the back of the cable modem for a reset switch (hole) and reset it. Then connect Ooma to the cable modem.
Telo with 2 Handsets, a Linx, and a Safety Phone
Telo2 with 2 Handsets and a Linx
To power it off, I have to remove the battery and the power cord.
One possibility, you made a typo on your Telo's MAC during registration. If this is the case, your only option is to call CS to short it out. (typical mistake 8 vs. B and 0 vs. D)
Two, as Murphy had said, the modem is blocking traffic when it sees a different MAC.
Even if you plan to setup with option A (modem > Telo > router > pc's), I recommend that you take the option B (modem > router > [Telo + pc's] during the initial setup. After the Telo up and running, you can easily switch it back to option A.

Comshaft VoIP cable modem (with VoIP service currently activated and running through it)
Linksys wireless router
Now that it is working, I will play with it and get it between the router and cable modem so that it is setup "correctly" and passing network traffic through.
Thank you guys for your help, didn't realize that it was a brick until you activated it... I figured it would at least pass through network traffic.
