Hi, I cannot make call to FreeSWITCH using Blink client (http://icanblink.com/). When I try to originate call, I see message: [ERR] switch_core_media.c:2720 a=crypto in RTP/AVP, refer to rfc3711 I already set for this user: <params> <param name="NDLB-allow-crypto-in-avp" value="true"/> <param name="auto-rtp-bugs" value="clear"/> </params> But both additions did not help. Restart freeswitch dies not help, too. Blink's SDP - with crypto requests - following. Please, suggest, how to fix this issue.
