libosip2-dev - 4.1.0-2.1 main

libosip2 header files and static libraries to assist in development of
programs wishing to use SIP.
.
The oSIP library is written in C, is thread safe and has no dependencies
except the standard C library.
.
oSIP could be used to implement an IP soft-phone as well as embedded SIP
software. oSIP is not limited to endpoint agents implementations and can
also be used to implement SIP proxies or registration services.
.
oSIP currently provides an API for the SIP message parser, SDP message
parser, and library to handle "SIP transactions" as defined by the SIP
standards (RFC3261).
