This module provides SCTP transport layer for Kamailio. SCTP is an acronym for Stream Control Transmission Protocol, read more about it at: http://en.wikipedia.org/wiki/Stream_Control_Transmission_Protocol The module itself implements the callbacks required by the core to receive and send SIP messages over SCTP sockets. The core Makefile variable SCTP must be set to 1 (which is by default set to 1 in Makefile.defs) and sources compiled with -DUSE_SCTP (automatically set when SCTP=1). In other words, if core Makefiles are not changed and SCTP variable is not overwritten from command line, then the SCTP support in core is enabled. Note: it is recommended to use recent versions of libsctp (>1.0.10) and kernel (>4.0.0) when enabling SCTP transport.
