Hi @ all, I´m trying to send SRTP packets to an asterisk 1.8.4 Gateway with my own developed softphone. I am using libsrtp to prtect the rtp packets. At the moment I do SRTP without a key management and creating my key with the crypto_get_random function of libsrtp. The key size is 30B. For creating the SDP offer with crypto I encode the key to base64.
The encryption type I want to use is AES_CM_128_HMAC_SHA1_80. for crypto_policy I use the crypto_policy_set_rtp_default. By sending the protected SRTP packets Asterisk Gateway ends up with SRTP_unprotect: authentication failure. My payload is 240B large and after protecting 250B. What could be wrong? How I can find out if I´m using same key and key derivations like asterisk?
