I'm trying to get linphone working through the VOIP and Chat accounts in Settings. After typing in username@sip.linphone.org + password + in advanced settings proxy : sip.linphone.org I can't get it to work with two acounts which work fine on a tablet and a laptop. Using it through OpenVPN also did not work. After I click on Sign In it starts loading and spinning and then it goes back to previous screen of Voip and Chat Accounts, without the yellow confirmation screen or green status appearing as in http://youtu.be/QKp0hZ9WL18?t=1m52s I tried it on WiFi (I don't have any mobile credit right now) on three N900s which have CSSU Stable, CSSU Testing and Nokia's last official firmware. What am I doing wrong?
