Happy new year!

maybe off-topic… but maybe someone _knows_ a solution.

I have a free SIP Account at linphone.org… calling other linphone.org users via SIP and receiving SIP calls from other users registered at linphone.org is no problem… just “dial” the username… BUT… as far as I understand the documentation, linphone.org offers internet wide SIP Calls… so… how can I call other users registered at other SIP-Providers?
I tried all well-known SIP URI Syntaxes but none worked… does anyone reliably know, if it is possible at all and if so, what is the dialstring looking like? (I am trying with zoiper softphone)

Unfortunately there is no support-email-address for linphone.org users…

thanks, yves
