I'm having trouble with SRTP calls between two internal extensions. Whenever I configure the phones to require SRTP calls has wrong. If I select "allow SRTP" so that encryption is not mandatory. I get only encryption on phone to FS in a call. Here's an example of what's happening: Extension 1003 --- SRTP --> FreeSWITCH -- RTP --> 1004 Extension 1003 <-- RTP ---- FreeSWITCH -- SRTP <-- 1004 Phones are LG-ERICSSON IP-8830E model. These phone is supported Secure RTP. These phones are configured to support SRTP, which is AES_CM_128_HMAC_SHA1_80. FreeSWITCH version is FreeSWITCH-1.2.23. conf/default.xml is configed. [image: 본문 이미지 1] I've setup the sip_secure_media=true variable as instructed from https://wiki.freeswitch.org/wiki/Secure_RTP but it's still not working by SRTP. Any help is greatly appreciated!
