Hello, There are two modes of media stream to be proxied or bypassed. 1. Default - "hard proxy" supplying trans coding, DTMF manipulations, etc. 2. Proxy - "light proxy" supplying only symmetrical RTP for mostly NAT traversal purposes. No media stream parsing is supported 3. Media bypass - RTP streams are bypassing FreeSWITCH at all. There are also two channel parameters affecting above modes: bypass_media and proxy_media. - Are these parameters independent? Meaning the combination: bypass_media=true AND proxy_media=true is possible. What effect will be? - Does it means that if I want to turn on "light proxy" I would always need to set bypass_media=false AND proxy_media=true? - How to set "hard proxy" (full media proxy) per channel before to bridge legs? Waiting for your replay ASAP. Thank you in advance. Best Regards. Max Kovalenko Team Leader VoIP & UC Team Managed Services Dept.
