i had custom device where i implement Secure SIP and SRTP(uvgRTP), i have a Linux machine which act as a PABX (Asterisk 22) and i have external application Zoiper(5) phone application.
Also I’m using SDP/SDES for keys sharing.
SIP signaling is working, but the audio not streaming properly. if i disable the media encryption in the pjsip.conf everything works well.
In the asterisk CLI it shows like this
SRTP unprotect failed on SSRC 2133353733 because of authentication failure 10 == SRTP unprotect failed on SSRC 2133353733 because of authentication failure 160
Asterisk denying my keys.
could you guys point out what i did wrong?
