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]
