SRTP switch_core_media.c:4522 Crypto not negotiated but required.
I'm new to Freeswitch and have udp, tcp and tls only calls working. However; I am having problems with tls and srtp. Call flow is bria client -- (udp+rdp) --> freeswitch -- (tls+srtp) --> sbc In my invite, I send the following SDP from Freeswitcch: m=audio 20606 RTP/SAVP 9 8 0 a=rtpmap:9 G722/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=crypto:5 AES_CM_128_HMAC_SHA1_80 inline:6dYwo00ZMUlaJXkdnTWAVsaqBsxXvVnPBO14sbO7 a=ptime:20 In the 180 and 200 response, I get: m=audio 6206 RTP/SAVP 8 a=crypto:5 AES_CM_128_HMAC_SHA1_80 inline:MrKNE3L5SSc9yb1o7G5BWJkcpLFvprrctnH/c6go a=rtpmap:8 PCMA/8000 a=sendrecv a=maxptime:20 Everything looks good. After the 200 ok, I see the following in the freeswitch log: 2017-08-17 08:48:34.801061 [DEBUG] switch_core_media.c:1395 looking for crypto suite [AES_CM_128_HMAC_SHA1_80] in [5 AES_CM_128_HMAC_SHA1_80 inline:MrKNE3L5SSc9yb1o7G5BWJkcpLFvprrctnH/c6go] 2017-08-17 08:48:34.801061 [DEBUG] switch_core_media.c:1400 Found suite AES_CM_128_HMAC_SHA1_80 2017-08-17 08:48:34.801061 [DEBUG] switch_core_media.c:1466 Set Remote Key [5 AES_CM_128_HMAC_SHA1_80 inline:MrKNE3L5SSc9yb1o7G5BWJkcpLFvprrctnH/c6go] 2017-08-17 08:48:34.801061 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMA:8:8000:20:64000:1]/[G722:9:8000:20:64000:1] 2017-08-17 08:48:34.801061 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMA:8:8000:20:64000:1]/[PCMA:8:8000:20:64000:1] 2017-08-17 08:48:34.801061 [DEBUG] switch_core_media.c:4504 Audio Codec Compare [PCMA:8:8000:20:64000:1] ++++ is saved as a match 2017-08-17 08:48:34.801061 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMA:8:8000:20:64000:1]/[PCMU:0:8000:20:64000:1] After receiving the ACK, I see the following in the fs log: 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [G722:9:8000:20:64000:1]/[G722:9:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4504 Audio Codec Compare [G722:9:8000:20:64000:1] ++++ is saved as a match 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [G722:9:8000:20:64000:1]/[PCMU:0:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [G722:9:8000:20:64000:1]/[PCMA:8:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMA:8:8000:20:64000:1]/[G722:9:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMA:8:8000:20:64000:1]/[PCMU:0:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMA:8:8000:20:64000:1]/[PCMA:8:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4504 Audio Codec Compare [PCMA:8:8000:20:64000:1] ++++ is saved as a match 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [G729:18:8000:20:8000:1]/[G722:9:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [G729:18:8000:20:8000:1]/[PCMU:0:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [G729:18:8000:20:8000:1]/[PCMA:8:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [opus:120:48000:20:0:2]/[G722:9:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [opus:120:48000:20:0:2]/[PCMU:0:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [opus:120:48000:20:0:2]/[PCMA:8:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMU:0:8000:20:64000:1]/[G722:9:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMU:0:8000:20:64000:1]/[PCMU:0:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4504 Audio Codec Compare [PCMU:0:8000:20:64000:1] ++++ is saved as a match 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [PCMU:0:8000:20:64000:1]/[PCMA:8:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [SILK:122:16000:20:0:1]/[G722:9:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [SILK:122:16000:20:0:1]/[PCMU:0:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4449 Audio Codec Compare [SILK:122:16000:20:0:1]/[PCMA:8:8000:20:64000:1] 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4365 Set telephone-event payload to 101@8000 2017-08-17 08:48:34.821064 [WARNING] switch_core_media.c:4522 Crypto not negotiated but required. 2017-08-17 08:48:34.821064 [DEBUG] switch_core_media.c:4767 sofia/internal/7202007917@10.251.145.154 Set 2833 dtmf send payload to 101 recv payload to 101 2017-08-17 08:48:34.821064 [NOTICE] switch_channel.c:3812 Hangup sofia/internal/7202007917@10.251.145.154 [CS_EXECUTE] [INCOMPATIBLE_DESTINATION] 2017-08-17 08:48:34.821064 [DEBUG] switch_ivr_originate.c:3661 sofia/internal/7202007917@10.251.145.154 Media Establishment Failed.
