Hi, i'm using the latest svn version of pjsua to communicate between two parties. I've set SRTP as mandatory for the media transport with the following parameters: --use-srtp 2 --srtp-secure 0 Everything is fine but Wireshark keep telling me "SRTP Payload with NULL encryption". Is that correct? Here is the snippet of the Offer SDP a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:VLDONbsbGl2Puqy+0PV7w/uGfpSPKFevDpxGsxN3 a=crypto:2 AES_CM_128_HMAC_SHA1_32 inline:lp5JGr/jKVzCzLyORdEMJjUPszZmioZ3zubVizTX and here is the encryption part of the Answer SDP a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:y71cYd6MyNqA9ywtm0rS2KBRDByG6/7vuQnyeL8T So my question, did pjsua used NULL encryption or AES_CM_128_HMAC_SHA1_80 as suggested in the Answer-SDP? Another question, when the caller uses (--use-srtp 1) and the callee has (--use-srtp 2) the call is always unencrypted. Is there a way to change that behavior in pjsua? Thanks in advance for any help Michael
