SJphone

GENERAL INFORMATION
SJ Labs SJphone can be used to place and receive calls from your computer. As of this writing, SJphone is available for Mac OS X, Windows 2000/XP, Linux, and Pocket PC 2003. The free version of SJphone does not include the G.729 codec which allows low bandwidth calls when using a dial-up modem. We recommend that you use a headset in order to achieve good quality calls.

NOTE: If you are using an internet connection with less than 80kbps upload/download speed; the free version of SJphone will not work well if at all for you because it does not include the G.729 codec. We do not recommend using the free version of SJphone on dial-up modem connections.

See below for information on where to download SJphone and how to configure it.

The SJphone product page can be found here.
The SJphone software can be downloaded here.
The SJphone manual can be found here.
