Website which can make a call to a given phone number

Is there any website/server through which I can do a tie-up for doing following:

1. I will pass my user Id and a phone number.
2. Using my user Id, it will know who I am and what is my phone number.

3.1 It will make a call to the phone number开发者_JS百科 which I have passed and to me and get both of us connected?

3.2 It will make a call to the phone number which I have passed and it should display my number in his mobile.

Please let me know whether any of these 3.1 or 3.2 is possible?

I'm not sure if this is exactly that you're looking for, but have a look at the Ribbit API.
