<div dir="ltr">Hello.<br><br>I've faced an issue when using rtpengine module with tls transport. When UA originates a call it pointed set of crypto<br>parameters in SDP, like that:<br><br>a=crypto:1 AES_CM_256_HMAC_SHA1_80 inline:PZASLY5HoxVo6Ljz2niwxqNJ+3A2mW71SgfL75cRFtShKQIvcKVF2Y39zGd1fQ==<br>a=crypto:2 AES_CM_256_HMAC_SHA1_32 inline:LRjGKIj8wvfxDP68+5XOEmlvO2ufqxDkhJ3hUQRWzjFulFr2kBztgSjrPSSACw==<br>a=crypto:3 AES_CM_128_HMAC_SHA1_80 inline:Nup7cVUaHGb+oQPf8gg1wDmjVJOZ5K+HZdhyovzz<br>a=crypto:4 AES_CM_128_HMAC_SHA1_32 inline:rjLdKaMyQ7+YQWCcIFKkVRLd+GZxkUogGK/4i1L0<br><br>But when Opensips relays original message to UA2, rtpengine removes all the crypto suite strings except the first one.<br>Unfortunately, there is no way to configure client's behaivior to send certain crypto suite.<br>In other side, UA2, that is PBX, doesn't support all crypto suites except AES_CM_128_HMAC_SHA1_80<br>Is there a way to configure Opensips/rtpengine to choose specific crypto string or to leave crypto set without changing at all?<div><br></div><div>Best Regards,</div><div>Sergey Pysanko.<br><br><br><br><div id="mt-signature">
