2025.01.0 29.01.2025
====================
- add support for server_type_compress=zstd [VS-1503]
- adding option audiograph_fftw_fork_mode = NO/yes (if enabled, fftw functions will be used in fork mode; this prevents the sniffer from crashing if something in the fftw library fails)
- add support for Ribbon SBC monitoring profiles [VS-1649]
- redesign packet_flags structure to resolve possible conflict between sip and rtp ports in t2_boost=high_traffic mode
- enable SO_KEEPALIVE flag when sniffer makes TCP connection (keylogger, sniffer->sniffer etc.)
2024.12.0 17.12.2024
====================
- fix missing RTP packets caused by SIP/SDP Packet Handling at Higher Traffic Rates: Previously, when t2_boost = yes (default setting), VoIPmonitor relied on the block of packets filling up quickly to trigger processing. For traffic rates below 200 Mb/s, an additional delay detection mechanism ensured blocks with a time difference exceeding 100ms between the first and last packet would be forwarded to the next thread. At higher traffic rates (>200 Mb/s), this delay detection was disabled, as it was assumed blocks would fill quickly. However, under certain conditions (e.g., low SIP traffic between threads), SIP/SDP packets could be delayed, causing RTP packets to be processed before the corresponding SIP/SDP packets. [VS-1669]
- add parameter sql_log_all_errors (overrides error log suppression)
- suppress the use of autocleanmingb if the disk size is smaller than this parameter
- suppress log entry 'Critical low disk space in spool...' if _maxpoolsize_autoclean is greater than the used space
- fix function SqlDb_mysql::getInsertId for client/server and cloud mode (fixes Configuration values in mysql have a higher weight) [VG-2911]
- pb thread optimisation in case voipmonitor is sniffing from multiple interfaces or is in receiver mode.
- use time in ms in active calls and registrations if there are cdr/register calldate columns for ms and even if the option time_precision_in_ms=yes is not specified
2024.11.2 02.12.2024
====================
- fix mirror receiver crash if mirror sender disconnects
- add dpdk parameter dpdk_mtu [VS-1665]
2024.11.1 27.11.2024
====================
- fix cleanup calls in t2_boost=no [VS-1664]
- fix srtp: completing the srtp key to the correct length, adding the srtp_use_all_keys (NO/yes) parameter to force the application of all known keys from all directions [VS-1661]
- limiting the number of attempts when creating a test table to verify compression algorithms in mariadb [VS-1660]
2024.11.0 25.11.2024
====================
- increase SIP processing by optimization of sip process split between threads (callid search and call packet processing), reduce locking [VS-1651]
- increase RTP processing by thread optimisations:
- optimization of packetbuffer output threads, decomposition of detach2 thread into main thread and subthreads [VS-1652]
- decomposition of defrag thread into main thread and subthreads [VS-1652]
- optimise distribution of t2 threads to subthreads
- fix potential crash in adjustSipResponse if set cdr_sip_response_number_max_length [VS-1655]
- fix issue with parse spd if media record contains zero port [VS-1648]
- automatic change of row_format parameter to dynamic if alter table fails with error ER_TOO_BIG_ROWSIZE (1118) [VG-2827]
- rcc fraud alert - 'time period rules' table - apply new gui checkbox to specify whether to convert time zone to gui time [VG-2898]
- add support for Cisco FabricPath [VS-1650]
- add CDR filtering by TCP/UDP/both protocol [VS-1609]
- fix creating sipcallerip_encaps column when creating new db [VS-1653]
- add parameter server_cp_store_simple_connect_response = yes/NO for enforce compatibility in client/server mode between the new server and the extremely old client [VG-2908]
- application of the cdr_force_primary_index_in_all_tables parameter to the cdr_stat_values and cdr_stat_sources tables [VS-1656]
- fix potential crashses when voipmonitor terminates
- extension of TcpReassembly::cleanup_simple to clean up infinite streams (applied when new option sip_tcp_reassembly_stream_max_length is set) [VS-1662]
2024.10.2 22.10.2024
====================
- better detection of rtp/audiograf using CDR.flags
- add multithread support without locks for fftw - can be enabled with audiograph_fftw_multithread_mode = yes
- dpdk: fix undefined reference to `rte_vdev_init'
- add option to allow write empty header's value if header is missing in first packet and is present in next packets [VG-2175]
- fix data availability detection in chunkbuffer if internal compression is enabled (tar_internalcompress_...) [VS-1642]
- add parameter dpdk_nb_mbufs_strictly=yes/NO to suppress the increase of the specified number of mbufs by a multiple of 1024
- fix potential crash in restart sensor in client mode
- allow to use %_ wildcards in conditions for numbers in fraud alerts [VG-1724]
- rcc fraud alert - time period rules table - apply new gui checkbox to specify whether to convert time zone to gui time [VG-2898]
2024.10.1 02.10.2024
====================
- fix crash when there are multiple c threads spawn (broken since 2024.08
- fix crashes in fftw library [VS-1639]
- fix compatibility with wireshark >= 4.2.3
- dpdk: detection of binding of interfaces and numa nodes, automatic creation of necessary hugepages, automatic assignment of rte threads to cpu cores
- add manager command for modify ssl_ipport - lock optimisations [VG-2866]
- adding values for displaying mos/jitter/loss items to active calls in gui [VG-2871]
- add manager command for modify ssl_ipport list,set,add,del which allows to change ssl_ipport without sniffer restart [VG-2866]
2024.09.4 20.9.2024
===================
- set usleep_minimal to 50us when vmware is detected (lowers CPU usage signifficantly)
- change default values for dpdk_read_thread and dpdk_worker_thread parameters from 'std' to 'rte'
- fix crashes in fftw library (initialization for multithreads use)
2024.09.3 18.9.2024
===================
- implement separate audio graphs files to spool/.../AUDIOGRAPH/ (spectrogram + wave) which allows to show it in GUI without needs to store RTP packets. New opeionts save_audiograph, audiograph*, maxpoolaudiographsize, maxpoolaudiographdays [VG-2874]
- fix race in transcribe calls

31.2.2 07.02.2023
==================
- change default value for ignore_mos_degradation_for_contiguous_packet_loss_greater_than back to 1024 (there are still many calls which get low MOS score due to transfered RTP eselwhere which is treated as packet loss)
31.2.1 01.02.2023
==================
- fix crash in srtp [VS-1415]
31.2 31.01.2023
