I have Fiber Optic internet. [100/100Mbps]

I tested my speed on Los Angeles Server (@speakeasy).
My result was 3800kbps down / 5900kbps up.
Anyway, i get about 10mbps with my wireless G router. Ping was 5.8ms or 4.2ms. Direct connection gives me about 80-90mbps speed.

Okay, that is my internet speed. I plugged ooma on my router because i did not want to loose my network settings.(i have ps3 and other stuff plugged into my router). I did forward some ports for ooma.

After few modem restart.
It works like charm!

I called my girlfriend's cellphone and voice quality was good and i didnt feel any delay over ooma.

Fewtimes, I heard static noises but overall it was not bad. However, it is definitely better than skype.

I don't know how to compare sound quality of VOIP, but skype sounds like 32kbps mp3 sound while ooma sounds like 64kbps-96kbps mp3 sound quality. I have no regret of getting ooma and I will recommend ooma to my friends.

Great to hear that things are working well for you. And that you are able to have a US number and great quality in South Korea.

Welcome to ooma! Since you'll be a great source of actual experience from Asia, make sure to visit the forum often. :cool:

Hello,
Can you tell me if you are still having good experience with calling to South Korea? I have been trying to call my friend in South Korea many times and is unable to get through. Most of the time, it would ring and then I get unable to connect at this time, try again later or something like that. Once in awhile, it would ring the phone but then cut off after a few seconds. I'm using speed dial so the number is correct since it does connect for a few seconds once in awhile.

dhkkim is using Ooma in Korea so probably not the right person to ask :)

Are you dialing Korea correctly?

Look here: http://www.howtocallabroad.com/south-korea/

  • 011 - US exit code; must be dialed first for all international calls made from the USA or Canada
  • 82 - Country Code for South Korea
  • area code - 1 digit for the capital Seoul and 2 digits for all other areas
  • phone number - 6 - 8 digits; area code followed by number total 8 or 9 digits for most landlines

For example, a Seoul Costco listed number is +82 2-572-5959

The way you dial using Ooma is 011 82 2 572 5959

Think about it a little, the Ooma device "thinks" it's in the USA, because it still goes through the Ooma Servers in the USA, so when placing a call from an Ooma device in located Korea, would still be "considered" a call from the USA to Korea.

Yeah but I doubt that dhkkim uses Ooma to place local calls in Korea :)

The number is correct since it does go through for a few seconds once in awhile. I used my Ooma to call her cell & home phone number that is stored on the phone so I'm not entering the wrong numbers.

I was able to call that Seoul Costco just now without a problem. When I use Ooma mobile app to dial overseas numbers using contact, sometimes I have issues. Perhaps next time, you can try manually dialing. If it works okay, then maybe add a pause between exit code/country code and the number itself and try.

Wow, thanks for placing that call! Hope you didn't waste the call just for me. I believe I tried to manually enter the number also but I will definitely try manual next time. Thanks for your help!
