pcapsipdump project is a tool for dumping (recording) SIP sessions (and RTP traffic, if available) to disk in a fashion similar to "tcpdump -w" (the format is exactly the same).
The difference is that the data is saved with one file per SIP session. Even if there are thousands of concurrect SIP sessions, each goes to separate file.
· libpcap 0.8.3
What's New in This Release:
· Avoid file trimming - add 'packet-buffered' (-U) option, add SIGTERM graceful handler
· Fix 64-bit platform pointer issues (use char* in arithmetics instead of uint32_t)
· Fix sip header parsing (RFC 3261 allows no-space-after-semicolon syntax, however it is not show in examples and, thus, rarely used)
· Include "verbosity level" command-line option
