Thanks Saul for the information. Yes, SRTP is the standard way for RTP encryption. But then in order to support SRTP, we will need to configure/change our server from Asterisk to any other SRTP supported server like FreeSWITCH. We want to avoid it as far as possible due to short deadlines. So is it possible if we encrypt/Decrypt the RTP data directly at client ends(at WM Handsets in our case) without involving server configurations using PJSIP? If yes then how it can be done? Thanks.
