Hi, i have some issues trying to make a HA with SRTP, i have that dialplan <extension name="salientes"> <condition field="destination_number" expression="^(\d{9})$"> <action application="set" data="ringback=${es-ring}"/> <action application="set" data="transfer_rinback=$${hold_music}"/> <action application="set" data="call_timeout=30" /> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="continue_on_fail=true"/> <action application="export" data="rtp_secure_media=optional"/> <action application="export" data="rtp_secure_media_outbound=forbidden"/> <action application="bridge" data="sofia/gateway/providerExt/$1"/> <action application="hangup"/> </condition> </extension> When i make a normal call in my FS1 it goes well, same when i do a normal call in a FS2, then the problem that i find is when i do a normal call in my FS1 (it takes AES_CM_128_HMAC_SHA1_32) and i do a "fsctl crash" in my "fs_cli", when the FS2 recovery the call, the audio drops in both ways, and if I use sngrep to see what is sending in the invite, i see that the crypto is "AES_CM_NULL_AUTH", in addition in the fs_cli on FS2 y found that error 2019-07-04 10:37:38.286877 [ERR] switch_core_media.c:1554 Error! No crypto to parse 2019-07-04 10:37:38.286877 [INFO] switch_rtp.c:4104 Activating audio Secure RTP SEND 2019-07-04 10:37:38.286877 [DEBUG] switch_core_sqldb.c:2617 Secure Type: srtp:sdes:AES_CM_128_HMAC_SHA1_32 2019-07-04 10:37:38.286877 [INFO] switch_rtp.c:4082 Activating audio Secure RTP RECV 2019-07-04 10:37:38.286877 [DEBUG] switch_core_sqldb.c:2617 Secure Type: srtp:sdes:AES_CM_128_HMAC_SHA1_32 Can someone give me some clarity about that problem? How I can solve this?
