Secure_bridge_signaling and and secure_bridge_media


I’m trying calls from BLINK SoftPhone to another SIP extension using TLS and SRTP

I’m using the two CHANNEL Options to see when the the calling channel use TLS and/or SRTP

The value of the two variables is always empty also when the call start from BLINK Softphone configured with TLS and SRTP. I can see the padlocks for TLS and SRTP on BLINK:

My dialplan:

exten => _100[0-2],1,Noop(Protocolo SIPTLS = ${CHANNEL(secure_bridge_signaling)})
same => n,Noop(Protocolo SRTP = ${CHANNEL(secure_bridge_media)})
same => n,Dial(SIP/${EXTEN},45,hHkKtTwWxX)
same => n,Hangup

Same behavior with PJSIP.

Any hint?


So is it a bug?
