Belle-Sip is a new SIP stack (RFC3261) developed by the Linphone team.
.
Belle-Sip supports multiple transports at the same time, has a dual
IPv6 and IPv4 stack, is fully asynchronous and implements the
+sip.instance and alias parameters. It also handles network
disconnections better, offers a privacy API and supports rich presence.
.
SIP/TLS is handled by mbed TLS (by way of bctoolbox), not OpenSSL.
.
This package contains the development files.
