Hi, We are currently using PJSIP on windows mobile handsets using Asterisk as SIP/Media Server. We need to encrypt/decrypt the voice data for transmission of RTP packets. Is it necessary to enable SRTP for this? Because, as far as possble we need to avoid the Server Settings configuration changes. If its possible then how to achieve it?
