On "http://www.asterisk.org/asterisknow", it states that I can build a Skype Gateway using AsteriskNOW. What can a Skype Gateway do? Where can I go to to learn more on how to build this Skype Gateway?
What I am wondering is if it is technically possible to forward calls to my office phone to my Skype account? For example, if someone calls my office number, the call will be forwarded to my Skype account.
I can't buy an online number as my country is not listed.
How do sites like ring2skype.com do this?
