1. Brekeke Product Name and Version:
sip3_14_7_4

2. Java version:
openjdk-11-jre / tomcat9

3. OS type and the version:
debian:bullseye

4. UA (phone), gateway or other hardware/software involved:
Freeswitch

5. Your problem:
We use VoIPMonitor to capture traces (SIP/RTP). We haven't been able to successfully trace TLS/SRTP calls (UDP/TCP non-TLS is fine). To do this, VoIPMonitor uses an SSL Keylogger https://www.voipmonitor.org/doc/Tls

Wondering (1) how your customers are going about debugging TLS/SRTP (2) has anyone been able to successfully get VoIPMonitor + SSL Keylogger to work?

Any additional thoughts/pointers appreciated.

Thanks,
Mike

For logging SIP packets exchanged over TLS, enable "Listener" category at [Diagnostics]->[Debug Logs] page.

For decoding/decrypting TLS and SRTP with Wireshark, the page below will help.
