- fix SIP TCP reassembler which in rare case combine two unreleated SIP packets pieces (all versions)
- add support for ieee 8021ad ethernet header (known as QinQ and is an amendment to IEEE standard IEEE 802.1Q-1998) - voipmonitor ignored such packets completely [VS-303]
- optimize RTP graph file handling
- fix crash if async write is not enabled (it is rare if this is disabled)
12.1.4 28.08.2015
=================
- fix cisco skinny V21 header version and all other header versions (calls were skipped)
12.1.3 28.08.2015
=================
- fix memory detection and small heap on 32bit version
- fix CPU% metrics in syslog on 32bit version (all versions)
12.1.2 27.08.2015
=================
- fix autocleaning feature for files in AUDIO - wav/ogg were not cleaning properly and disk space was leaking (all versions)
12.1.1 26.08.2015
=================
- immediately close calls which ends with 301 or 302 SIP response and do not wait 5 minutes which prevents to use all memory (high calls in syslog)
- do not abort sniffer if saveaudio = yes (or wav/ogg files are enabled in capture rules) and there is no space to create such files (all versions)
- fix custom headers in case there are two headers with the same name but different case sensitive letters
12.1 25.08.2015
===============
- store detected RTP ptime (packetization) into the database (a_rtp_ptime, b_rtp_ptime)
- allow to specify ogg audio format in capture rules and allow to select savertp header in capture rules
- do not use T1 thread and inter thread compression (t1CPU) which now allows to utilize full heap instead of only low inter-thread ringbuffer in case T2CPU is blocked due to CPU spikes.
- remove alter for obsolete table sensor_conf
- having lzo library is now mandatory
- disable manager and receiver if reading from file (-r)
12.0 20.08.2015
===============
- make LZO compression default for rtp storing (8x faster)
- reduce locking in t2CPU threads by 1000x which allows now to sniff over 1.1M packets (2 Gbit traffic)
- do not report packet loss if there is sequence and timestamp change without mark bit
- fix MySQL issue 'Deadlock found when trying to get lock; try restarting transaction' by rearranging query order
- disable storing cdr_sipresp (every SIP response in database) which was too much for database to handle (reduces SQLq growing)
11.11.5 19.08.2015
==================
- fix broken active calls in 11.11.4 (use select on descriptor)
- fix q850 reason string logic
11.11.4 18.08.2015
==================
- fix support for multiple vlan tag in packets [VG-672]
- fix issue with long manager command for getfile_in_tar (fixes retrieving long RTP files from remote sniffers)
- fix receiver mode terminating
- add cdr_rtpsrcport configuration option
- fix random crash when q850 reason is enabled (which is when mysql columns were added)
11.11.3 14.08.2015
==================
- reenable tcmalloc allocation library if present (speedups sniffer)
11.11.2 14.08.2015
==================
- fix cloud sniffer DNS possible crash on timeout in curl library
11.11.1 13.08.2015
==================
- fix capture rules in case savertp = header and capture rule is set to save full RTP (it was still saving only rtp headers)
- retrieve audio from remote sniffer in case there is audio wav/ogg generated and not convert it from pcap
- fix issue with name_sensor option (duplicated string)
- fix crash in sender mirrorer when receiver disconnects
11.11 11.08.2015
================
- implement LZO compression algorithm and use it by default for RTP compression which is 8x faster then default gzip but about 10% less efficient. To enable gzip back set pcap_dump_zip_rtp = gzip
- be more tolerant when comparing time between sender and receiver in mirroring mode (2 seconds)
- static builds fixes SSL/TLS decoding again (was not working since >= 11.10.2
11.10.3 07.08.2015
==================
- fix mirroring mode broken in 11.10.2
11.10.2 06.08.2015
==================
- fix storing requests to table cdr_sip_history
- fix storing pcap if sip.Call-ID is too long in case tar=yes is enabled (which is by default enabled) - all versions
- do not allow sniffer sender (mirrorer) to connect in case the time difference is > 1 second between sender and receiver which fixes call timeouts [VS-923]
- set cdr.bye also for call states: zombie_timeout_exceeded and sipwithoutrtp_timeout_exceeded
11.10.1 03.08.2015
==================
- fix configuration option savertp = no which was still recording RTP (fixes >= 11.9.4)
11.10 30.07.2015
================
- fix memory leak when doing reindex files - all versions (around 40MB per reindex)
- fraud SIP flood rule can now count SIP request distribution
- fraud SIP REGISTER can now filter user agent
11.9.4 24.07.2015
=================
- fix saverfc2833=yes option in case savertp=no or savertp=header - DTMF were still truncated despite the saverfc2833 was enabled.
11.9.3 22.07.2015
=================
- use hour and day filter from alerts in fraud [VG-647]
- fix crash at exit - add call regfailedcache->prune(0) before delete sqlStore
- set limit conten_type byte for ssl v2 (
11.9.2 16.07.2015
=================
- Fix ssl / tls decoding for clients who sends ssl version 2.0 CLIENT HELLO instead of SSL 3 or TLS
- Fix cleanspool safe to not wipe more data than it should
11.9.1 16.07.2015
=================
- fix 11.9 active calls in GUI which did not reported all ringing calls (with 18X) until calls were picked up
11.9 14.07.2015
===============
- add sequential fraud alert [VG-557]
- fix issue with buffer configuration which can be too low and can cause MEMORY FULL deadlock.
- report MEMORY FULL via manager command to catch that state via GUI
- implement name_sensor configuration option which overrides ID when spooldir_by_sensorname is enabled
- fix crash when send call over HTTP is enabled and disabled
- fix prematurely end of call when 300 multiple choices received. Sniffer closed the call immediately without waiting for other SIP messages [VS-286]
- store also BYE to mysql sip history
- new option save_sip_history (more info in voipmonitor.conf) [VS-278]
11.8.1 04.07.2015
=================
- fix crash if SIP Content-Length is negative
- fix race leading to crash when ssl decryption is enabled (duplicate call tcpReassemblySip.clean)
11.8 04.07.2015
===============
- fix bug in cleanspool which can lead to crash (all versions)
- add new option spooldir_by_sensorname [VS-282]
- fix issue with string 'set buffer memory limit to ...'
- cocncurent calls fraud - add support for new filtrers - called numbers and destination ip addresses [VG-598]

10.0.18 12.8.2014
=================
- force RTP resync in case of reINVITE which fixes false packet loss detection and low MOS score.
10.0.17 12.8.2014
=================
- adjust jitterbuffer f1 simulator to not lower MOS score for latencies <50ms
10.0.16 7.8.2014
================
- fix cleaning of active REGISTER which did not expired
- fix clean_obsolete_dirs which cleaned more than it should (not enabled by default)
10.0.15 7.8.2014
================
- fix zombie calls when sniffer is loosing packets. Add new sipwithoutrtptimeout so rtptimeout can be keep at reasonable values (300). See new config/voipmonitor.conf comments.
- close call if there is no 18X or 2XX responses
- fix search country by phone prefix
- remove useless debug message "prevent recursion of connect to db"
- fix dtmf reorder when storing dtmf to database
- fix http issue with 100-continue before 200-OK with eq ack at end stream
- fix false high PDV in case there are DTMF frames
- fix IP capture rules which matches rules according to best fit based on higher network mask. for example 192.168.0.1/32 rule will match last if there is also rule 192.168.0.0/24.
10.0.14 5.8.2014
================
- do not report packet loss if RTP mark bit it set
10.0.13 5.8.2014
================
- fix: if RTP stream starts with CNG frame and seq number is > 0 it detected huge false packet loss and astronomic avg jitter.
10.0.12 5.8.2014
================
- fix MOS score in case there is large packet loss gap - the MOS did not reflected it at all
- fix last sip response code is always 0 if the call was canceled before the ring.
10.0.11 31.7.2014
=================
- fixes fixed jitterbuffer implementation - all versions. Certain packet loss patterns caused high MOS score.
10.0.10 30.7.2014
=================
- fix condition for ignore local ip in fraud alerts
- add sipports command to manager
- fix set local country for local number in fraud
- log to syslog when removing files in spooldir
- supress warning about ddos confusing message
10.0.9 28.7.2014
================
- automatically enable fraud modules
10.0.8 23.7.2014
================
- fix 10.0.6,10.0.7 release (crashes)
10.0.7 23.7.2014
================
- fix 10.0.6 release (crashes)
10.0.6 22.7.2014
================
- fix SQL queue which stuck when max_allow_packet in mysql is default 1MB (which is by default)
- do not add another IP/port but update the old one taken from SDP on RE-INVITE or other cases with SDP - take the unique session id from SDP header for matching which fixes problem with multiple RTP streams in calls which are not related to the call. Fixes all versions. On high throughput this would lead to less CPU and less I/O.
- fix offline reading pcap files - sql handler was terminated sooner
- fix: run pcapcommand after all packets are written to pcap file
- reset jitterbuffer simulators when receving DTMF to not affect MOS score negatively
- fix audio sync issue for g.711 CNG frames
- add siren7 decode (G.722.1) support
10.0.5 14.7.2014
================
- fix filter in live sniffer
- optimize query for select min id in database backup
- fix typo in configure script
- add plcdisable config option and --plc-disable cmd line for G711
- add information about sniffer upgrade file size to error log
- Fixed install command for libcurl4-openssl-dev
- add update_dstnum_onanswer option
- try to reconstruct both audio if 200 OK is missing (or 18X with SDP)
- support Yes or YES in voipmonitor.conf
10.0.4 30.6.2014
================
- fix high MOS scores for fixed50 and fixed200 MOS scores. Fixed50 acts like 250ms and fixed200 like 400ms. (9.3 regression - broken since 5.5.2014)
10.0.3 27.6.2014
================
- fix mirroring between 32bit and 64bit sniffers (9.3 regression)
10.0.2 27.6.2014
================
- fix mos score for g729 (if enabled in voipmonitor.conf which is not recommended anyway) which was always high even for huge packet / PDV loss
10.0.1 24.6.2014
================
- fix GRE protocol (10.0 regression)
- fix IP defragmentation
- fix crashing when decoding to WAV (10.0 regression)
- redesign timestamp reorder warning (10.0)
- fix SIP SMS hide message capture rules
10.0 19.6.2014
==============
after several months of releasing 9.4 and 10.0RC/BETA versions there is new stable version 10.0 with many enhancements and bug fixes. The most interesting part is transparent pcap file compression and saving packet optimizations which allows to store thousands of simultaneous calls which was not possible before. The sniffer is now able to write pcap files for very high number of calls per second (>6000 / sec). Read the full changelog below:
Optimizations
-------------
- reimplement saving pcap files and add native gzip pcap and graph files which is enabled by default. Zipping is done in threads which dynamically grows. Use open/write sys calls instead of libc fwrite/fopen/fclose to allow store files at >6000 calls/second rate (impossible with libc fwrite/fclose functions). Any writes to file are asynchronous by default using different queue which will not block processing packets. New parameters in config/voipmonitor.conf - pcap_dump_bufflength, pcap_dump_zip, pcap_dump_writethreads, pcap_dump_writethreads_max, pcap_dump_asyncwrite, pcap_dump_asyncbuffer. Those optimizations does not require cachedir for very high I/O loads now.
- properly dequeue remote sensors by the timestamp to prevent race conditions or if sniffing on interface = eth1,eth2
- Optimize SIP parser which is now much faster
- do not try to parse callid on UDP packet if it cannot be SIP (can save some CPU)
- save few kB for each jitterbuffer channel (3 per RTP stream) - removed unused structures
- release calls from memory sooner and do not wait on rtptimeout for some cases
- end calls sooner than the rtptimeout if there is no further communication after 401 SIP response
- be more tolerant in jitterbuffer simulater to burst RTP packets - add 200ms more so the MOS is not negatively affected
- if mysql procedure fails run repair table mysql.proc which is the most common source of the issue
- implement new mysql fine tunning options - mysqlstore_concat_limit and mysqlstore_concat* - see voipmonitor.conf for more details
- modify packetbuffer log drop statistics (heapoverrun and drop packets on interace)
- repair table mysql.proc at every sniffer start (it is broken after hard restart very often...)
- shorten register sip message timeout from 30 to 5 seconds (helps to manage RAM when there is REGISTER flood) and add option sip-register-timeout so it can be set to custom seconds
