Getting some call transactions:

1. 2011/01/26 - 12:05pm call from work -----------> to ooma connected home number: FAIL: No ring, then fast busy
2. 2011/01/26 - 12:10pm call from work -----------> to ooma connected home number: FAIL: 1 Ring, then fast busy
3. 2011/01/26 - 12:11pm call from work -----------> to ooma connected home number: FAIL: No ring, then fast busy

Other times I get the expected 5-6 rings then the OOMA voicemail service, why would this be so erratic and unreliable?

Same thing with calling from other numbers, maybe 1 in 6 attempts is successful, incoming or outgoing.

Why is the OOMA device so poorly engineered that it cannot be behind a NAT?

Lame!

You're wrong. My Telo has been on a NAT-ed LAN since the day I got it.

My main computer (it runs Unix) has two NICs. One uses a static public IP number, connected to my incoming DSL line.

The second NIC has a static IP number on a LAN using IP addresses drawn from a private non-routable subnet. On the LAN are several other computers, a wireless hub, a NAS, a printer, and my Ooma Telo, all running with static IP numbers..

The computer does routing, including NAT, between the two NICs. No big deal, and no problems.

Thanks highq, your post gives me some hope that I will be able to get this sorted out.

Are you putting the OOMA in the DMZ?

I don't know why I should bother with any DMZ settings on the Telo, since it has no outbound connections to anywhere: the Home Port is empty.

OTOH, in order to access the Telo's internal web pages, I have of course asked it to forward port 80 to itself at 172.27.35.1.
