Murata-san, A is certainly possible, B depends on how you want to connect and what provider you are using. You can get a Digium X100P FXO card and connect it to the RJ-11 analog phone jack on your ADSL modem. Digium's card does not have JATE type approval but if you use an ADSL splitter so that you are not connecting through to NTT, then you don't need any JATE approved card. Otherwise, you need to get a winmodem from a Japanese importer with JATE type approval, but it must have the Intel 537 chipset (aka Ambient) which is very hard to get these days in Japan. Kuroutoshikou used to sell a modem with this chipset but they stopped selling them. In principle you could use Asterisk's ability to talk to SIP proxies and connect to your SIP provider directly without any analog converter boxes in between, but in practise this is "muzukashii". The providers don't easily give you the necessary information and even if they do, it usually doesn't work. At present, the only VoIP service in Japan that doesn't expect you to use an analog telephone adapter (inside your ADSL modem) is Taraba.net but they are at present only accepting connections from X-Lite and X-Pro softphones. This is expected to change in the near future though as they are getting their customer support ready to deal with other types of devices.
