I can’t find that this is possible with the **AudioBridge** plugin. However, I’m interested in having **RTP participants** , not just listeners but speakers, in addition to **WebRTC participants**. Is this possible, or have I missed something in the documentation? If it’s not possible, do you have any suggestions? Thank you very much. **Edit:** Reading **AudioBridge** configuration file I found this: ![image](https://global.discourse-cdn.com/free1/uploads/janus/original/1X/0232857808823857415ac0d1244c926338e3886d.png) So, I check what ports are open in Janus, but I can’t found any port specified in `rtp-port-range`. What type of ports, UDP or TCP ports? Thanks ---

These blog posts will give you some more info on how plain RTP participants work in the AudioBridge plugin: > **[Bridging AudioBridge and SIP with Drachtio | Meetecho Blog](https://www.meetecho.com/blog/audiobridge-sip/)** > > One question we often get is: how do I use the SIP and VideoRoom or AudioBridge plugin together? The short answer is that directly you can't, because of how Janus is conceived.

Ahhh yes, in the response object to join or add new forward I get the host:port params to send media from external RTP sources. Thank you so much Lorenzo! ---

No, only `join`. The forwarders are used exclusively for RTP _out_, from the bridge to an external address, they cannot be used to inject RTP _into_ the bridge, that’s what RTP participants are for. ---

> EDIT: Please ignore this reply, I think it is my bad because I am using the same join from browser to join also with plain rtp. Sorry for the noise I’m not sure if this is an **AudioBridge** bug or something wrong with my configuration. I have the following configured in the **AudioBridge** configuration file: ```auto rtp_port_range = “13000-13050” local_ip = “192.168.10.10” ``` When I **join** the room using the parameter in **Janode** : ```javascript rtp_participant : { ip : ‘192.168.10.10’, port : 13000 } ``` upon joining, the browser log returns the following: ```auto you have joined to room { "room": 1234, "feed": 8715613318794055, "rtp_participant": { "ip": "192.168.10.10", "port": 13000, "payload_type": 100 }, "rtp": { "ip": "192.168.10.10", "port": 13000, "payload_type": 100 }, "participants": [] } ``` but doing a port analysis in shell I get: ```auto [root@vm-desarrollo janus]# netstat -tunlp | grep janus tcp 0 0 0.0.0.0:62203 0.0.0.0:* LISTEN 21221/janus tcp6 0 0 :::62201 :::* LISTEN 21221/janus udp 0 0 192.168.10.10:49216 0.0.0.0:* 21221/janus udp6 0 0 :::5002 :::* 21221/janus udp6 0 0 :::5004 :::* 21221/janus udp6 0 0 :::5102 :::* 21221/janus udp6 0 0 :::5104 :::* 21221/janus udp6 0 0 :::5106 :::* 21221/janus ``` So, Janus open UDP port `49216` not between the range `13000-13050`. Also I can’t get informed in response of `join`, the port `49216`. I am missing something?
