We are Israel. We purchased an Ooma Telo and a Dlink 2650u router to take with us. In Israel, we contacted Kavei Zahav to install a landline. They installed a Dlink2500u modem and an Audio Codes MP202B/2FXS VoIP phone. The cabling is: wall to dsl input on modem to WAN port on AudioCodes box. LAN port on Audio Codes to ‘internet’ port on Ooma. ‘Home network’ on Ooma to Dlink2650u router port. The result is we can receive inbound phone calls on the Ooma Telo but cannot make US calls on it. We have computer internet access.

The Audio Codes box is set to PPPoE with an ip address of 10.100.101.10 per Kavei Zahav’s instructions.
The Ooma settings are:
Network Connection – Dynamic (DHCP)
Static IP – 10.100.101.100
Modem port MAC address – Automatic
Home Port IP address – 172.27.35.1
Home Port Netmask – 255.255.255.0
DHCP start address – 172.27.35.10
DHCP end address – 172.27.35.160
DMZ – blank
Quality of Service – upstream speed – 384
Device Status – rev 1.41189
Network Modem – Connected (10.100.101.101)
Network Home – Connected (172.27.35.1)
Ooma Tunnel – Disconnected
Services
Telephony 1185 running
DNS 506 running
Web Server 1091 running
VPN 27977 running
Free 185408

How can we make this work?
Thanks in advance for your help.

These are not compatible.
If you need to use a static IP address, set the network connection to static.
You also need to set the mask and the DNS entries to the values they gave you.

Thank you, Murphy, for your reply.

Question: who is supposed to be giving us mask and DNS values? Ooma, or Kavei Zahav?

Thanks again,

When Kavei Zahav gave you the static IP address they should have also given you the mask, gateway IP address, and DNS IP addresses that their system uses.

If our static ip address is 10.100.101.100 then what should the netmask and DNS be? Also, should the values be entered under DNS 1 or DNS 2 ? Kavei Zahav told us that our DMZ should be 10.100.101.100, what is that, is that the same as the DNS?

They should give you the numbers that they want you to use.
That's actually a private class A IP address and not a public IP address.

You can try this as my best guess.

Mask 255.0.0.0
Gateway 10.100.101.1
DNS 1 10.100.101.1
DNS 2 leave blank

That's just a guess. Your ISP should be telling you what you are supposed to use.

I called the ISP and they said:

Static IP: 10.100.101.100
Netmask: 255.255.255.0
DSN 1: 10.100.101.1
DNS 2: 80.179.25.100
Router address: 10.100.101.1 (this one she wasn't so sure about)

We rebooted the entire system, and its still not working, help!!!!

Kimo Sabe? :D Sorry, in my mind, it sounded that way at first.

I am clueless. IMO, I think you are able to make outgoing call, but unable to receiving call. However, in reality your situation is reversed of what I am thinking.

This is the first time I see an ISP using private IP addresses for their customer. check out this link
Private IPv4 address spaces

In this situation, you are at the mercy of the ISP. You need to call your ISP and ask them to unblock some port(s) that ooma needs, and you need to call ooma to get the list of ports that they needs to open. Good luck with that.

I try an analogy here. Imagine that I under used my internet bandwidth, and I try to recoup some $$ by resell those unused bandwidth to my neighbors, and subsequently the whole neighborhood using static ip 192.168.x.y. or 172.30.m.m or 10.R.S.Q.

I have control of the router(gateway) I can do anything I want. However, those, who uses 'my isp,' is not able to run any of the servers like web, ftp, or even bit torrent, etc. for the outside world (i.e. beyond my gateway). However, these servers are ok "within" for all of my neighbors who use 'my isp.'

PS
Please note that, those ip in the Private_IPv4_address_spaces will be dropped at the first internet gateway outside of your home network, and/or you get the reply "address not found."
