VoIP monitor Files

Optimizations
- open pcap file descriptor lekas
- close unused graph files to save a lot of memory
- if calls changes SSRC for every packet (broken device) do not let voipmonitor to take all RAM
- allow to turn off jitterbuffer simulators which takes the most CPU and a lot of RAM
- speedup processing SIP packets. Now the complexity changed from O(N) to O(Log(N)) which is huge speedup performance for a lot of concurrent calls (>500)
- speedup writing CDR after the call ends 
- implement threads to voipmonitor which now can handle thousands of simultanouse calls.
- move testing of SIP packet before testing it for RTP which saves a lot of CPU for high SIP rate packets. 


Features
- implement ODBC. Now voipmonitor can store to any ODBC enabled database like MSSQL.
- implement custom SIP header X-VoipMonitor-Custom1 which it's value will be saved to cdr.custom_header1
- lOG PID for each syslog message to differentiate between several voipmonitor instances
- Implement MOS calculation for G.729 codecs and make this configurable via voipmonitor.conf mos_g729
- allow configure multiple SIP ports
- support sniffing on tun interfaces (openvpn for example). (All DLT_RAW interfaces are supported now)
- implement stereo WAV left channel is callee right channel is caller
- save RTCP packets to pcap file
- implement simple TCP server for managing voipmonitor and getting list of calls
- implement IP and tel. number filters so voipmonitor can now record RTP for selected networks or tel. prefixes. It is done in new mysql tables filter_ip and filter_telnum. Reloading is posible via voipmonitor TCP manager interface (sending command reload)
- Support VLAN tag packets when sniffing on all interfaces "-i any". VLAN worked only for -i ethX
- implement TCP SIP transport and TCP SIP reassembly packets (SIP TCP packets divided to multiple small packets)
- implement postprocess command for pcap file (--pcap-command). Added  %dirname% and %basename% to pcapcommand + add example how to move records from /dev/shm to another place after call is ended.
- added mysql index for callername column
- added reverse string ekvivalent for called,caller,callername and trigger to do automatic reverse. now for search caller like %number is better to use caller_reverse like CONCAT(REVERSE(number),'%') which will use indexed search


Bugs
- fix crashes caused by memory corruptions and some race conditions
- fix many wav sync issues, double speed wav issues and one-way wav issues
- fix typo in SQL table calee -> callee which resulted in not saving callee information to whohanged
- fix pcap file leaks
- fix "myqslhost" -> "mysqlhost" typo. Please update your configuration files!
- fix ogg format
- after 3XX,4XX,5XX some additional packets were not saved
- fix mysql connection handling on error condition
- fix User-Agent header which was stored to called instead of caller
- fixed SIP last response CDR value for cases where 200 OK is missing after BYE.
