changelog

siproxd is a proxy/masquerading for the SIP protocal.

0.5.3
=====
  14-Feb-2004:  - Released 0.5.3
		- Removed superfluous backslashes for line continuation
  11-Feb-2004:  - Use same SIP port number for RX & TX (-> support
                  symmetric SIP signalling)
   7-Feb-2004:  - Fix for local-UA to local-UA RTP proxying, symmetric
                  RTP was not working.
                - logging routines now use a MUTEX to be thread safe.
                - RTP proxy: fixed a bug that could lead to a deadlock
                  on very rapid HOLD/unHOLD sequences.
   1-Feb-2004:  - Added handling of Max-Forwards header
                - a detected via loop results in an 482 Loop detected
  31-Jan-2004:  - Allow 2 of my vias in header to let 2 UA's sitting
                  behind the same siproxd have conversation together
                  UA1 -->--\   >   /-->--\
                            siproxd       Registrar
                  UA2 --<--/   <   \--<--/
                - Redone code for evaluation if a received packet
                  is coming from the inbound or outbound network
                - RTP streams are now identified by call_id AND
                  USERNAME of the contact header. This provides
                  support for RTP proxying between 2 UAs sitting on the
                  inbound network. -> Calls between local UAs going via
                  siproxd should now work.
                  UA1 -->--\
                            siproxd 
                  UA2 --<--/ 
                - Rewriting of SUBSCRIBE messages should now work.
                - Removed obsolete prototypes from rtpproxy.h
                - If the RTP stream in one direction is found to be
                  aborted (sendto() failure), also stop the stream
                  for the opposite direction

0.5.2
=====
  31-Jan-2004:  - Released 0.5.2
  30-Jan-2004:  - If RTP proxy is disabled, don't rewrite incomming
                  SDP bodies (patch from Robert H鰃berg)
  29-Jan-2004:  - new doc/RFC3261_compliance.txt and comments in the
                  code that refer to the RFC.
  28-Jan-2004:  - don't die on INVITE requests that include no Contact
                  header - which is legal. (patch from Robert H鰃berg)
                - RTP proxy: don't try to forward empty RTP packets
                - renamed some variables of rtp_proxytable_t to make
                  better sense (changed meaning in fullduplex RTP proxy)
  27-Jan-2004:  - added doc/KNOWN_BUGS
                - better branch parameter calculation (via header),
                  now honors RFC3261 for stateless proxies (section 16.11)
                - SIP request: remove a Route header pointing to myself.
                  This was an issue with Linphone 0.12.1.
                  (patch from Robert H鰃berg).
                - removed IPCHAINS & IPTABLES (netfilter) proxy support
                - RTPPROXY correction: match RTP ports crosswise -
                  use one single port (and socket) on each side (inbound/
                  outbound) to send and receive RTP traffic for every
                  active stream (patch from Christof Meerwald).
  22-Jan-2004:  - ./configure option: --enable-static to build
                  a completely statically linked executable
                - REGISTER honors the expires parameter
                  of the contact header
                - Contact header of REGISTER response must be
                  rewritten back to the local (true) URL
  18-Jan-2004:  - security_check_raw:
                  size check: >= 16 bytes
                - at exit, check registration file to be writable
                - no WARNING if SIP user-agent header is not supplied.
                - Call logging: distinguish between In & Out
                - include branch parameter for via headers

0.5.1
=====
  22-Dec-2003:  - Released 0.5.1
  21-Dec-2003:  - possibility to log call establishment
  17-Dec-2003:  - full duplex RTP proxy (many thanks to Chris Ross for
                  his work on this). Up to now, only the RTP *Relay*
                  has been tested (it works with KPhone, BudgeTone)
                - fix: SIP phones that allocate a random port for
                  incomming SIP traffic should now work (like BudgeTone)
                - fix: some SIP phones do change the RTP port number
                  during a session (like KPhone during HOLD/unHOLD)
                - textual corrections
  15-Dec-2003:  - use only even port numbers for RTP traffic
  05-Dec-2003:  - some changes & enhancements inspired by Chris Ross:
                  * 183 Trying *may* contain SDP data
                  * compare_url: now does compare the scheme,
                    if a host is not resolveable, hostnames will be
                    compared as strings
  04-Dec-2003:  - have registrations persistent across restarts of
                  the daemon ('registration_file' config option)
  29-Nov-2003:  - some documentation & FAQ updates

0.5.0
=====
  26-Nov-2003:  - released 0.5.0
                - included preliminary support for IPTABLES (netfiler)
                  based systems.
  24-Nov-2003:  - some fixes in sockbind() (FreeBSD) by Jeremy Shaw
  23-Nov-2003:  - got the gethostbyname() failure problem solved.
                  (the resolver needs a shared lib that was tried
                  to load AFTER chrooting...)
  22-Nov-2003:  - utils.c: use gethostbyname_r() in favor of
                  gethostbyname - if available (siproxd uses threads!)
                - some small items & cleanup
  19-Nov-2003:  - Integrated a patch from Chris Ross:
                  * have siproxd compile on Solaris and BSD/OS (more to come)
                  * ./configure option --with-libosip-prefix
                  * properly handle getopt_long()/getopt()
  18-Nov-2003:  - readconfig.c: include sysconfdir to the list of locations
                  where siproxd will search for its config file
  14-Nov-2003:  - rtpproxy.c: sys/types.h needed for *BSD
                - tested: siproxd builds on FreeBSD 4.9
   2-Nov-2003:  - rtpproxy bugfix: On repetitive INVITES, the UDP media
                  port could end up as -1 in the rewritten packet.
   1-Nov-2003:  - siproxd can use another outbound proxy (chaining)
                - Linux 2.4.x: siproxd with RTP relay could hang
                  on termination (Thread termination). Fixed.
                  
0.4.2
=====
  31-Oct-2003:  - released 0.4.2
                - Makefile: install siproxd to sbin (was bin)
  24-Oct-2003:  - SPEC file: included config files & more docu
  19-Oct-2003:  - included compiling support for DMALLOC debugging
                - fixed 2 memory leaks in proxy.c

0.4.1
=====
  12-Oct-2003:  - released 0.4.1
  12-Oct-2003:  - Local registration of UAs was simply broken. Fixed.

0.4.0
=====
  11-Oct-2003:  - released 0.4.0
  08-Oct-2003:  - rtpproxy_masq: fixed an issue in port allocation
                  which lead to syslog entries from IPCHAINS complaining
                  about 'already used connection' in the syslog.
                - added INFO() for incomming SIP Calls
  04-Oct-2003:  - Siproxd now also works as outbound proxy 'only',
                  means that local UAs may register themselfes to a
                  3rd party registrar and use siproxd only as oubound
                  proxy for masquerading purpose.
                - fixed some errors with callid handling (NULL pointers)
  24-Sep-2003:  - corrected the calling arguments of rtp_masq dummy
                  routines (non IPCHAINS capable kernels)
  22-Sep-2003:  - '\0' termination of read() SIP telegram from line

0.3.6
=====
  22-Sep-2003:  - released 0.3.6
                - Code cleanup for RTP proxy
  07-Sep-2003:  - IPCHAINS based UDP tunneling (kernel masquerading)
                  for RTP traffic (still experimental - but seems to work).
                  To activate it, just set 'rtp_proxy_enable' equal 2
                  in the config. NOTE: siproxd must then be started by
                  root (but dropping privileges works).
  05-Sep-2003:  - configure.in: test for pthreads before libosip (RH9.0)

0.3.5
=====
 30-Aug-2003:   - released 0.3.5
 20-Aug-2003:   - security tests: responses may have empty SIP URI
                  don't fail there.
                - increase size of call_id for RTP proxy table and
                  include a size check.
                - rtpproxy: cleaned up some stuff with handling of FD's

0.3.4
=====
 05-Aug-2003:   - released 0.3.4
 31-Jul-2003:   - now supports OSIP2 only (due to rather big changes
                  in the API libosip -> libosip2). Compiles cleanly w/
                  libosip2 2.0.2

0.3.3
=====
 05-Jul-2003:   - released 0.3.3

                  should now work (better) with multiple media streams
 23-Apr-2003:   - FAQ updates: RTP internals
                - more debug and error testing (MOREDEBUG)
  6-Apr-2003:   - build options for FLI4L builds (libc5 & uClibc)
