I have run into an issue with rtpengine and the ICE=force option. To quote the rtpengine README
With `force`, ICE attributes are first stripped, then new attributes are When using the force option where I think it will be appropriate I found it also adds crypto attributes. I believe this invokes SDES security. If the setup attribute is also present ( DTLS security ) the call fails with bad description. SDES=off does not prevent this behaviour. The error message from the UA says there cannot be both. a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:/ msDyiV8x6qpcH4m1iEmxo8aqAAhhkGctQbxvkNy a=crypto:2 AES_CM_128_HMAC_SHA1_32 inline:JgDv7fMfKd1GQcFq9Jn0tMf1C5DE0VaRDe6Js8D6 a=crypto:3 AES_192_CM_HMAC_SHA1_80 inline:CiCkAETMov/tbVsqykp7j3/ PB7aUfQjv+nozBQuOUMBnJlrm8bU a=crypto:4 AES_192_CM_HMAC_SHA1_32 inline: 6ktVsgwfiGg4US2BLWuV3XpCt0fvkiuFgcEr8n83KDln8w9ar+c a=crypto:5 AES_256_CM_HMAC_SHA1_80 inline:l1pr/ 67vqwthDdnRoSaTbGvRPBNP7uHIhjfeG8InuqWQZjLkumU5MVKz2mAujw a=crypto:6 AES_256_CM_HMAC_SHA1_32 inline:V+K2bK8Zahr9KX7zswVwM2cpZ+/ g8hMD4a5PmJzncH8WgDnCH/xLH0CFRwYKgg a=crypto:7 F8_128_HMAC_SHA1_80 inline:Z00dhmeQwuttjeRawylGKannT7KbBZhDExDxETNo a=crypto:8 F8_128_HMAC_SHA1_32 inline:R5Vqt9WQ1wU76GcS7CvDosgbWHRYLV7CRnGre+uV a=crypto:9 NULL_HMAC_SHA1_80 inline:TP2aKDSKe8G9E7kd+w7XpOhcItzd0xmBN3g06WC1 a=crypto:10 NULL_HMAC_SHA1_32 inline:xKFUEuwLpexe84KKCulBSThMx75T74U7/K7qJbKi a=setup:actpass
