To set up Region Pinning in LiveKit, here’s a friendly guide to help you through the process: For Inbound Calls: • Start by using a region-based endpoint when you configure your SIP trunking provider. The endpoint format looks like this:

{sip_subdomain}.{region_name}.sip.livekit.cloud

. • Just replace

{sip_subdomain}

with your LiveKit project ID (without the

p_

prefix) and

{region_name}

with one of the supported regions:

eu

,

india

,

sa

, or

us

. • For example, if you want to pin to India, your endpoint would be:

bwwn08a2m4o.india.sip.livekit.cloud

. • Don’t forget to update your SIP provider’s Origination URI with this region-based endpoint. For Outbound Calls: • When creating an outbound SIP trunk via the API or CLI, use the

destination_country

parameter. • Set this parameter to the two-letter ISO 3166-1 alpha-2 country code that matches your target (for example,

"in"

for India). • Here’s an example JSON configuration to guide you:

{
  "trunk": {
    "name": "My outbound trunk",
    "phone_number": "+15105550100",
    "username": "myusername",
    "password": "mypassword",
    "destination_country": "in"
  }
}

• Then, create the trunk with this command:

lk sip outbound create outbound-trunk.json
