how can we get hold of the sip body?

Thanks for reaching out, Utkarsh. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

raw SIP body which the livekit sip dispatches

Thanks — regarding the raw SIP body LiveKit dispatches: We do not expose the raw SIP message body (full INVITE/SDP/MIME payload) via LiveKit APIs or webhook payloads. The SIP body is not included in the dispatched event payloads. If you need the raw body, you can capture it externally. Options I can help with: • Enable logging/capture on your SIP proxy or gateway that sits before/after LiveKit. • Enable packet capture (pcap) on the network interface handling SIP to inspect INVITE/200 OK bodies. • If you control the SIP gateway instance, I can guide you on what to enable in its logs or where to place captures. Which option do you want to pursue, and tell me whether you control the SIP proxy/gateway or only the LiveKit side? I’ll provide step-by-step guidance. , with interactive elements

i am using self hosting mode, livekit sip is deployed in ec2 instance running via docker-compose

Thanks — since you’re self‑hosting LiveKit SIP on EC2 via docker-compose, you can capture the raw SIP body locally. Which of these do you want to try? And confirm you have SSH + docker-compose access to the EC2 instance. • Capture network traffic with tcpdump/pcap and inspect in Wireshark (captures INVITE/200 OK bodies). • Enable/augment logging inside the SIP gateway container (stream container logs to host file or stdout and increase verbosity). • Add a small proxy (sip logger) between your SIP trunk and LiveKit to log full SIP messages. Tell me which option you prefer and I’ll give step-by-step commands for your EC2/docker-compose setup. , with interactive elements

yes i can access ec2 instance, give me the best solution

Great — since you have SSH access to the EC2 instance, the two most practical options are: Option A — Capture SIP packets (recommended, simplest, exact raw body) 1. SSH into the EC2 instance. 2. Install tcpdump (if not present): ◦ Ubuntu/Debian: sudo apt-get update && sudo apt-get install -y tcpdump ◦ Amazon Linux/CentOS: sudo yum install -y tcpdump 1. Run tcpdump to capture SIP (UDP 5060 or your configured port) to a pcap file: ◦ sudo tcpdump -i any -s 0 -w /tmp/sip_capture.pcap port 5060 ◦ If using TLS/TCP or a different port, replace

port 5060

with the correct port/protocol (e.g.,

tcp port 5061

). 1. Reproduce the SIP call flow you need to capture, then stop tcpdump (Ctrl+C). 2. Transfer the pcap to your workstation: ◦ scp ec2-user@your-ec2:/tmp/sip_capture.pcap . 1. Open in Wireshark or use tshark to extract SIP bodies: ◦ tshark -r sip_capture.pcap -Y sip -V ◦ Or to extract SDP bodies only: tshark -r sip_capture.pcap -Y "sip && sip.Method == \"INVITE\"" -T fields -e sip.Payload ◦ Adjust filters for INVITE/200OK as needed. Notes: Use capture filters if traffic volume is high (e.g., host x.x.x.x and port 5060). For TLS, packet capture won’t decrypt the payload without the keys. Option B — Log full SIP messages from the container (if supported by the gateway binary) 1. Identify the SIP container name: ◦ sudo docker-compose ps 1. Stream logs to see current output: ◦ sudo docker-compose logs -f sip_service_name 1. If the gateway supports verbose logging via env var or flag, add it to your docker-compose.yml for that service. Example pattern (replace with the service name and actual var/flag your gateway supports): ◦ environment: ▪︎ LOG_LEVEL=debug ▪︎ SIP_DEBUG=true ◦ Or add

command: ["./gateway-binary", "--log-level", "debug", "--sip-debug"]

1. Apply changes and restart the service: ◦ sudo docker-compose up -d --force-recreate sip_service_name 1. Tail logs and search for SIP payloads: ◦ sudo docker-compose logs -f sip_service_name | grep -i "sdp\|INVITE\|Content-Type" Notes: I don’t have a specific documented env var name for LiveKit SIP’s raw SIP-body log toggle. If enabling debug-level logs in the container doesn’t show raw bodies, fall back to Option A or use an in‑line SIP proxy/logger. If you want, I can provide the exact tcpdump/tshark commands tailored to your SIP transport (UDP/TCP/TLS) and port, or show an example docker-compose snippet to add debug logging.
