Re: [SR-Users] No secure attributes from rtpengine in SRTP/RTP bridge mode

Hi, Richard! Thank you for quick feedback! There is no such attribute in SDP payload from the latest Mozilla (v.29). v=0 o=Mozilla-SIPUA-29.0 371 0 IN IP4 0.0.0.0 s=SIP Call t=0 0 a=ice-ufrag:083b4837 a=ice-pwd:dac461d48770be5e1dae6c450e144bf3 a=fingerprint:sha-256 C3:AA:DB:75:D7:60:FC:B6:94:A7:81:4F:74:A2:FF:44:4B:17:AE:D3:64:37:37:D1:AC:1A:F5:D4:86:1E:4F:7A m=audio 52775 RTP/SAVPF 109 0 8 101 c=IN IP4 192.168.0.101 a=rtpmap:109 opus/48000/2 a=ptime:20 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv a=setup:actpass a=candidate:0 1 UDP 2130444543 192.168.0.101 52775 typ host a=candidate:0 2 UDP 2130444542 192.168.0.101 63139 typ host a=rtcp-mux But it presents in SDP from Chrome (v.34) v=0 o=- 1634904605592690072 2 IN IP4 127.0.0.1 s=- t=0 0 a=group:BUNDLE audio a=msid-semantic: WMS C8ATLgPd2jIcc5q799L9XU3rTROMajedYbdI m=audio 51817 RTP/SAVPF 111 103 104 0 8 106 105 13 126 c=IN IP4 192.168.0.101 a=rtcp:51817 IN IP4 192.168.0.101 a=candidate:3350409123 1 udp 2122260223 192.168.0.101 51817 typ host generation 0 a=candidate:3350409123 2 udp 2122260223 192.168.0.101 51817 typ host generation 0 a=candidate:2301678419 1 tcp 1518280447 192.168.0.101 0 typ host generation 0 a=candidate:2301678419 2 tcp 1518280447 192.168.0.101 0 typ host generation 0 a=ice-ufrag:WyHALLFH6CaQmCIA a=ice-pwd:9BMkH9d7D9pfSjZmLSkunxrW a=ice-options:google-ice a=fingerprint:sha-256 46:6E:E0:18:4A:C5:06:A8:26:85:ED:FE:16:C1:86:5E:8D:BC:4D:D9:F2:1A:75:81:A1:A7:CE:5A:79:4D:B7:22 *a=setup:actpass* a=mid:audio a=extmap:1 urn:ietf:params:rtp-hdrext:ssrc-audio-level a=sendrecv a=rtcp-mux a=crypto:0 AES_CM_128_HMAC_SHA1_32 inline:cDj0wVDUUZ/1etNd9MFQjeqwn/ii3RsxQLraXUln a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:KKzZx0iwM2udfGNv+pBoB/BDVBvsFsMcQczVZDOQ .... No success for both browsers. It's should be noticed that Chrome provides both SDES ("crypto") and DTLS ("fingerprint"+"setup:actpass") attibutes (does DTLS have priority in a such case?). However rtpengine doesn't provide such SRTP data. May be any suggestions? kind regards, Alexey 2014-04-25 18:02 GMT+04:00 Richard Fuchs <rfuchs(a)sipwise.com>om>:
