Hi,
I am working on an experiment where I would measure the performance differences between RTP and SRTP.
Test environment:
RaspberryPi 4 with Asterisk FreePBX 15 as VoIPserver,
2 Laptops as Softphone (PhonerLite)
I have problems with SRTP/TLS.
I only found a documentation for FreePBX 14, not for 15 and 14 does not support the Raspberry Pi 4. And there are differences!
What I’ve heard so far TLS must also be enabled for SRTP.
I work on a network without internet, so I only created a private certificate.
I created the certificates with this instruction
wiki.asterisk.org/wiki/display/AST/Secure+Calling+Tutorial
I accomplished to register the phones and make normal RTP calls.
Thanks for your help
