<br>
Hi!<br>
If you make SRTP to RTP to Asterisk, you possibly will need vice versa<br>
conversion (when request coming from Asterisk to client with SRTP).<br>
<br>
Can you describe the logic of test case: (UA-A (SRTP) --> Kamailio (make<br>
SRTP->RTP) .... etc.<br>
<br>
Because your explanation is difficult to understand.<br>
<br>
Cheers!<br>
<br>
