i'm working SIP, and our SIP provider supports IP based authentication, is it possible in livekit

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

give me config for outbond

Thanks — I’m responding to your request for an outbound SIP trunk configuration with IP-based authentication. Below is a ready-to-use example JSON for an outbound trunk that includes IP whitelisting via `allowed_addresses`:

{
  "trunk": {
    "name": "My Outbound Trunk",
    "outbound": {
      "address": "<http://sip.provider.com|sip.provider.com>",
      "username": "your_username",
      "password": "your_password"
    },
    "allowed_addresses": [
      "203.0.113.10",
      "203.0.113.11"
    ]
  }
}

Notes and next steps: • Replace

<http://sip.provider.com|sip.provider.com>

,

your_username

, and

your_password

with your provider’s values. • Replace the IPs in

allowed_addresses

with the SIP provider IPs you need to whitelist. • Use the LiveKit CLI to create the trunk: a. Save the JSON as

outbound-trunk.json

. b. Run:

lk sip outbound create outbound-trunk.json

If you prefer to create the trunk programmatically, here’s a Python SDK example:

from livekit import api

lk_api = api.LiveKitAPI(
    url="<https://your-instance.livekit.cloud>",
    api_key="your-api-key",
    api_secret="your-api-secret"
)

outbound_trunk = await lk_api.sip.create_sip_outbound_trunk(
    api.CreateSIPOutboundTrunkRequest(
        trunk=api.SIPOutboundTrunkInfo(
            name="My Outbound Trunk",
            address="<http://sip.provider.com|sip.provider.com>",
            username="your_username",
            password="your_password",
            allowed_addresses=["203.0.113.10", "203.0.113.11"]
        )
    )
)

Would you like: • A version that uses provider IP ranges/CIDR notation instead of individual IPs? • Help validating the IPs your SIP provider gave you before you apply the config? • A version of the example in another SDK (Go, JS)?
