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

Can someone give me some clarity about that problem? How I can solve this?
