Hello, there were some limitations in sngrep for capturing tls traffic:
* https://github.com/irontec/sngrep/issues/112 Not sure if there was any work afterwards to improve. The best place to ask in on sngrep project. Anyhow, I want to add that if you use Kamailio, then you can load sipdump module and get the traffic stored in pcap files -- it requires master branch: * https://www.kamailio.org/docs/modules/devel/modules/sipdump.html#sipdump.p.mode For stable branches, sipdump can store the traffic in text files.
