This is a odd project since I only need to get some things explained =)
What I intend to do is to start a small VOIP service to provide cheap calls to some specific countries to landline phones.
Provide cheap calls from landline phones in Greece to landline phones to Russia.
What is needed when it comes to hardware? How do I connect to the phonesystem in Russia?
Some other questions will be asked so no work has to be done. Just explain things to me =)
