sip-signaling-server

Overview ¶

SIP signaling-only server — no local RTP socket.

RTP media servers register themselves via HTTP (POST /v1/nodes/register) and send heartbeats. On INVITE the least-loaded registered node is chosen; Call-ID is bound to that node for ACK/BYE.

Usage:

# Terminal A: SIP signaling (registry + SIP UDP)
SIP_UDP_PORT=5060 SIP_LOCAL_IP=192.168.28.128 SIP_CONTROL_PORT=8080 \
  go run ./examples/sip-signaling-server

# Terminal B: RTP node (registers to signaling)
RTP_NODE_ID=rtp-a RTP_MEDIA_IP=192.168.28.128 \
  SIP_REGISTRY_URL=http://192.168.28.128:8080 \
  go run ./examples/sip-rtp-server

# Terminal C: another RTP node
RTP_NODE_ID=rtp-b RTP_MEDIA_IP=192.168.28.129 \
  SIP_REGISTRY_URL=http://192.168.28.128:8080 \
  go run ./examples/sip-rtp-server

Env:

• SIP_UDP_HOST signaling bind host (default 0.0.0.0)
• SIP_UDP_PORT signaling UDP port (default 5060)
• SIP_LOCAL_IP advertised Contact / Via IP (auto if empty)
• SIP_CONTROL_HOST registry HTTP bind host (default 0.0.0.0)
• SIP_CONTROL_PORT registry HTTP port (default 8080)
• RTP_NODE_TTL_SEC drop nodes without heartbeat (default 45)
• RTP_CONTROL_URLS optional static seed URLs (dev only)
