SETUP: Comcast provider (CA), Motorola SB6121 Modem>Ooma>Cisco EA4500.

When i go into the tool>port scan> Basic it yields this result:
Ports Status for 24.10.120.1
Denied Ports : UDP 53, UDP 123, UDP 514, UDP 1194, UDP 3386, UDP 3480, UDP 10000, UDP 10500, UDP 11000, UDP 11500, UDP 12000, UDP 12500, UDP 13000, UDP 13500, UDP 14000, UDP 14500, UDP 15000, UDP 15500, UDP 16000, UDP 16500, UDP 17000, UDP 17500, UDP 18000, UDP 18500, UDP 19000, UDP 19500, UDP 20000

However if i do advance Scan it yields this result:

Ports Status for speedtest.ooma.com

Denied Ports : UDP 123

So does that mean there is a problem on my end? do i need to contact my ISP or is there something i can do to fix this on my own?

Did the Built in mac selection as well, no automatic.

Also Setup QoS,
Up: 500 and Down: 1000

Probably changing the Ooma Telo Internet Port from Automatic MAC address to Use Built In MAC address will help with the dropped calls.


Ooma has never explained yet, what the uses are for the Ooma Setup Port Scan Tools. These tools were released in this last Ooma Telo Firmware update.

If you are NOT having any problems making and receiving Ooma phone system calls, don't do anything with the ports.

I have only one port that shows blocked for the Basic Scan.

In the past I have gone in and opened that port in my router.

But when I compared the two (with port open and with port closed), I could detect no difference in Ooma service. Some of the ports listed, if opened may compromise security, so if you decide to open ports in your Router, make sure you have good virus and Internet security software installed on each of your computers.

Others have posted the same number of blocked ports as you have in the Basic Scan, but report having no problems with their Ooma Telo?????

If you go here: https://www.ooma.com/app/support/advance ... vice-ports , you can see which ports Ooma uses.


Also go here http://forums.comcast.com/t5/Connectivi ... 553/page/9 to see what others are doing to prevent service interuptions.
