Plain RTP participant

Plain RTP participant not working

Hi all,
I using AudioBridge Plugin to make Room with config:
“body”: {
“request”: “create”,
“room”: 123456,
“sampling_rate”: 8000,
“description”:“test room”,
“audiolevel_ext”:True,
“allow_rtp_participants”: True
}
And after that, i add a RTP participant to this room:
“body”: {
“request”: “join”,
“room”: 1320437480,
“display”: “LINH”,
“codec”: “pcma”,
“rtp”: {
“ip”: “103.199.49.53”,
“port”: “11486”,
“payload_type”: 8,
“audiolevel_ext”: 1
}
}

Afterthat, Janus AudioBridge return

     "rtp": {
        "ip": "103.199.55.43",
        "port": 10014,
        "payload_type": 8
     }

And i using Sip server to send audio to Janus with this infomation. All participant in this room listen audio.
But Janus no not send RTP audio to my Sip server, my softphone can’t listen anythink

have one way Audio.
Thanks for support
