SRTP: Unable to create media session: No active media stream after negotiation
Hello!
I'm trying to enable media encryption:
acc_cfg.mediaConfig.srtpUse = PJMEDIA_SRTP_MANDATORY;
But when I'm calling from one client to another, I receive an error
I pjsua : 13:43:04.491 pjsua_call.c .....Unable to create media session: No active media stream after negotiation (PJMEDIA_SDPNEG_ENOMEDIA) [status=220048]
I have an android app, running on two smartphones.
From phone A I'm starting to INVITE phone B:
