Fixed IP and SIP registration for your LiveKit agents

RelayDock sits between your carrier or PBX and LiveKit Cloud. It keeps your numbers registered, gives your trunks one static IP to allowlist and shows you exactly where a call stopped.

How it works

One hop between your carrier and LiveKit

Keep your carrier, numbers and agent. RelayDock adds the SIP edge that LiveKit Cloud doesn't have: registration, a static IP and a clear view of every call.

  1. 01

    Your carrier or PBX

    RelayDock registers with your carrier account or PBX extension. Trunks send calls from addresses you allow in the panel.

  2. 02

    RelayDock edge

    Holds the registration, checks the source IP and digest, and routes each call to the right LiveKit project from one static IP.

  3. 03

    LiveKit Cloud

    Your agent answers through LiveKit SIP. Nothing changes in your agent code.

What you get

Built for the calls your agents take

  • Registration bridge

    Carriers and PBXs that only speak REGISTER can reach LiveKit. RelayDock holds the registration and emails you when it drops.

  • One static IP

    Allowlist a single shared address for calls in both directions. Dedicated IPs come with Enterprise.

  • Direct or Relay audio

    Direct keeps media between your carrier and LiveKit. Relay anchors it at the edge when NAT or firewalls get in the way.

  • Diagnostics you can act on

    Every call shows its SIP code and the hop where it stopped. An inbound check confirms routing from your own phone.

  • Test calls and alerts

    Place a test call through the whole chain. Get an email when a registration, your LiveKit key or the edge needs attention.

  • REST API

    Endpoints, numbers, calls and usage are in the API, with keys per integration and an OpenAPI reference.
