[SR-Users] sngrep TLS connection

[Daniel-Constantin Mierla]

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.

Cheers,
Daniel
