SIP on Sailfish/Aurora with s1p

Have now installed s1p on my wifes and my two SFOS Xperia 10’s and made two Linphone.org accounts and got back info from linphone.org for both accounts:

SIP identity: sip:username@sip.linphone.org

Mail: my/hermailadress…

Username + Password,

Domain/Proxy: sip.linphone.org

Enterd this into s1p configuration, and left Authentification User + Server Port empty.
The other fields like Register Interval (3600), Bind Address (0.0.0.0), Bind Port (5060) I left as it was and made no change.

After restart of program it connects to Linphone.org and reports ‘registered’. I have a number keyboard on the screen. On dialing ‘normal’ phone numbers, some speaker/headphone… icons appear but there’s no connection, and I cannot disconnect, have to close the app and reopen it.

What number has my wifes and my account now? How can I make a Linphone to Linphone call, using my wifes/my usernames? Can only enter numbers. What number have I now on Linphone?

Linphone Homepage is not helpful, FAQ “coming soon” there, therefore I ask here…
