ZRTP implementation in FREEPBX

Hello I can make zrtp work on freepbx. There is one important thing! No call records with zrtp because peer-to-peer connection. FreePBX is just for signaling SIP protocol. Also all your phones must have zrtp supporting. Best regards, Serg.

Hello! I understand you need to encrypt and secure your communications. I have 10 years of experience in Asterisk PBX and FreePBX. I've already done an encrypted call implementation for a fintech client. I recommend encrypting SIP packets with TLS also. Not only RTP. It would be ideal if we chat about it before you award the project so I can clear all you doubts. Hope we talk soon. Best. F.
