SJphone
SJphone is a free VOIP softphone. It can be installed on:
- Windows (XP SP2, 2000 SP4, Vista, Vista x64), Windows CE (Pocket PC, Windows Mobile), Linux, MAC
It supports both SIP and H.323 standards, and has a brilliant logging feature if you are having trouble getting a call through.
Note for Vista x64 (64 bit version) users:
On my Dell Lattitude I couldn't make a call or run the Audio Wizard, it crashed the program. I found a workaround:
- Select: Menu -> To Advanced Mode
- Select: Menu -> Options
- Select: the Audio tab.
- Select: Advanced Settings...
- Uncheck: Enable Adaptive Echo Canceller
After that, I can make a call, and it is also possible to run the Audio Wizard.... I found this by trial and error, first I disabled everything in the 'Audio' tab, and reduced the sample rate, then I grdually enabled everything again.
