video phone?

I know this is probably really 20th -century, but has anyone ever used a videophone to communicate from the UK to the USA?  My mother has Parkinson's disease and can't use a computer, so Skype is not an option. I am really looking for something that is as easy as a phone with a video screen so it will be easy for Mom to use.  Her speech is affected by the Parkinson's so I think it would be really helpful if we could see each other, or so she could point to things if she can't get her words out.  I'd need something that would work both in the UK and the USA that I could set up for her in a few months when I go back to the USA to visit.  Any ideas on technology I should look for when shopping for a phone system would really be helpful, thanks!

Sorry - I don't want to toot my own horn. I work for a company that makes video technology for corporate use. It is actually very 21st century and high in demand now! 
We have one personal desktop phone called E20 that is super easy to use take a look here: http://www.tandberg.com/products/tandberg_e20.jsp

Please keep in mind that the success of using a video phone depends on your network. Hence, it is crucial to make sure you have sufficient bandwidth where you/your mother live. Otherwise, the best video phone won't help.

i have one of these , i also bought one for my mother who has no problmes using it and my brother in mexico. Not cheap but very easy to use.
