07/06/2025, 5:34 PMTo receive an incoming phone number in LiveKit and use it to identify the user, follow these steps:
1. Set up an inbound trunk: Configure the trunk to accept calls from specific phone numbers. For example: `{
"trunk": {
"name": "My trunk",
"numbers": ["+15105550100"],
"allowed_numbers": ["+13105550100", "+17145550100"]
}
}`This setup specifies which caller phone numbers are permitted to connect through your trunk.
2. Create a dispatch rule: Define how incoming calls are handled. The dispatch rule determines how SIP participants and LiveKit rooms are created for incoming calls. When a call is received, LiveKit SIP authenticates the trunk credentials, matches the dispatch rule, and creates a SIP participant for the caller, placing them in a LiveKit room accordingly.
3. Use metadata for identification: Configure additional properties for incoming calls, such as SIP headers, participant metadata, and attributes. This allows you to use the caller's phone number as an identifier.
Let me know if you need further assistance with setting this up!

07/06/2025, 5:35 PMTo use the caller's phone number in the agent, I've got a neat trick for you! 😊 Think of it like getting to know your caller a little better through their phone number.
Copy code
# Add this after `await ctx.connect()`:
participant = await ctx.wait_for_participant()
# Check if the participant is a SIP participant
if participant.kind == rtc.ParticipantKind.PARTICIPANT_KIND_SIP:
# Access the caller's phone number
if participant.attributes['sip.phoneNumber'] == '+15105550100':
<http://logger.info|logger.info>("Caller phone number is <tel:+1-510-555-0100|+1-510-555-0100>")
# Add other logic here to modify the agent based on the caller's phone number
