Sharique,
You can set the country to any country other than US and it will be the same.
As for a manual, you can find all the standard Quintum manuals on their web site under the customer service area and there are some sample configs there as well.
For step-by-step instructions, I can provide this for you at a very reasonable fee. If you would like to discuss this with me, please email me at mike_voip@hotmail.com and make sure that you have Quintum in the subject line.
Mike
