can you send me a list of all web site ( pc 2 phone ) ?

Coco..

A couple of things.  Researchers are very wary of questions requesting
"all" of something, regardless of the topic.  Secondly, even a
thorough list of what you are looking for would take a great deal of
research.  Also, your question is vague.  What kinds of websites are
you looking for?  Are you talking about a product with the name
PC2Phone or are you looking for sites that offer voice over IP
options?  Any additonal information you can provide to guide
Researchers in the right direction will give you question a much
better chance of getting answered.  I also suggest you read
