Verify that tls/SRTP crypto is being used with chan_pjsip?

Is there a simple way to verify from within the Asterisk console if tls is being used for signaling and SRTP for the audio streams with chan_pjsip?

I am looking for something like “pjsip show crypto”. A simple way to check the crypto status of active channels, without reading SIP messages or sniffing the traffic.

Is that possible?

Yes, with the CHANNEL function. However, if mission critical, you should capture and analyse the packets.
