I use it for peer to peer sip calls using IPv6 (and Cjdns for stable IP and encryption). The OP was attempting to use a peer to peer connection via IP4.
Potential problems: 1) the normal IP4 syntax is sip:[email protected]. For IPv6, it is sip:user@[2001:db8:1234:5678::90]. I've never tried leaving out the user as the OP did (and I haven't used IPv4 in 15 years). (Note that the address book works just fine for storing raw ips of contacts ready to dial.) 2) Using peer to peer IP4 is *very* problematic unless you have a public IP. NAT is very complex to work around for SIP. The solutions offered by linphone (like STUN) all involve a public server. If you want to do peer to peer SIP, I would give up on IP4. You need IP6. 3) On 3.6.1, I need to turn off "guess_hostname" and set contact to my peer to peer sip url by editing ~/.linphonerc. Linphone tends to guess wrong for peer to peer use. 4) Windows is very wonky on networking - it may be preventing peer to peer operation in some way, and the operative assumption is that Windows users do most things through centralized services.
