How are you connected to the Internet?  Like 99% of consumers you are
probably sitting behind a firewalling router.  This is prone to
interfere with protocols like SIP and usually requires the involvement
of either a SIP proxy on the router (if the firmware offers that
functionality) or STUN server provided by the VoIP provider
(stun.1-voip.com in your case), so you should look into that.

Starting linphone on a terminal can give more detailed information on
what is going wrong.  You can also enable logging in Linphone directly
under Preferences -> Advanced -> Enable logs and then inspect the log
files produced (your initial message contained 0 error or diagnostic
messages leaving us with nothing to work with).

Just out of curiosity: What is the current version of Linphone in Mint?

That's a pretty impressive level of dedication for tech support.
