Hello, In RTPEngine recording-daemon, I enabled "forward-to" option to unix_socket. All things work right, I got metadata at first, then media packets (RTP-UDP-IP). The metadata for each calls is received just at first packet, but i want to know, if i have more than one concurrent active call in RTPEngine, How can i distinct which media packet was from which call? Thanks with Regards. --Mojtaba Esfandiari.S
