- We suppose you already have
a wideband internet connection like DSL, 802.11a/b/g/n wireless, or old
good wired Ethernet or E1/T1. Dial-up users are welcome too, but a
codec must be used.
- You can use any modern PC running MS Windows ME/2K/XP, MAC OS or
Linux. Also you can use PDA running PocketPC 2003; choose and download
your version of SJphone from our website.
- Full-duplex sound is a must. To check it, run a recorder and player
at the same time. If the both work properly, you have a full-duplex
soundcard, that's OK.
