Hi, I am using the following ser.cfg with ser and mediaproxy, but I am getting the audio only in one direction. This does not seem a problem of NAT, as the nathelper is correclt rewriting the sdp messages, and the aor shows all clients bound with public IP. Earlier t_on_reply call in route[1] was causing an error “sl_reply_error used: I'm terribly sorry, server error occured (1/SL)” when one calls from one phone to another. Earlier I was getting proper bi-directional audio when I was using STUN instead of mediaproxy.

Is there something wrong with my ser.cfg
