SJphone is a VOIP softphone that allows you to speak with any other softphone, any stand-alone IP-phone, or using ITSP with any traditional wired or mobile phone.
SJphone project supports both SIP and H.323 standards and is fully inter-operable with most major VOIP vendors and ITSP. For SJphone Profiles concept explanation please go to our support page.
Also you can try our current releases that we have not fully tested yet. They are just preview versions for new features, so we do not guarantee their stable work.
Attention!
Having SJphone installed is not enough to talk except over your local network. You have to obtain an account with any ITSP like Vonage or Free World Dialup, or install your own VoIP server.
