How to enable Srtp in FreeSWITCH?

Question

FreeSWITCH

I use a bunch of csipsimple and freeSWITCH. I wanted to enable encryption for now, without using tls, I activated the srtp mode in csipsimple. As a result, calls from a mobile subscriber can be made, but the reception does not work.
I rummaged through the wiki, found a somewhat vague description on https://wiki.freeswitch.org/wiki/SRTP
I tried to enter

<condition field="${sip_has_crypto}" expression="^(AES_CM_128_HMAC_SHA1_32|AES_CM_128_HMAC_SHA1_80)$" break="never">
       <action application="set" data="sip_secure_media=true"/>
       <action application="export" data="sip_secure_media=true"/>
     </condition>

- did not help.
Who can tell me what needs to be done in order to use SRTP normally in both directions?

Answer 1

csipsimple - sometimes works crookedly. Try to check Zoiper

Answer 3

Alexander followed your advice and tried Zoiper. He crashes the moment he plays Leg B and gets an invite from FS. And just CSipSimple works fine. However, in conjunction with the asterisk, the same Zoyper works. Someone solved this problem? Been fighting for a month now...
