Thanks — I’m responding to your question about whether the same phone number can be used for both outbound and inbound calls with LiveKit Cloud + Telnyx.
Short answer: Yes. You can use the same phone number from Telnyx for both making outbound calls and receiving inbound calls when it’s configured as a SIP trunk with LiveKit Cloud.
What this means and what to check:
• LiveKit supports SIP trunking so a single provider trunk (Telnyx) can handle both inbound and outbound call flows.
• Make sure your Telnyx number is provisioned and routed to the SIP trunk you configure for LiveKit.
• Configure the LiveKit telephony/SIP settings so inbound calls from Telnyx are delivered to your LiveKit agent/room, and ensure LiveKit is authorized to originate outbound SIP calls using that trunk/number.
• Verify any Telnyx-specific settings (call routing, SIP credentials, and caller ID configuration) so outbound calls present the expected phone number and inbound calls are forwarded to LiveKit.
If you’d like, I can help with the next step — which would you prefer?
• Step-by-step checklist to configure Telnyx + LiveKit for bidirectional calling.
• Troubleshooting items to verify if you’ve already set this up but it’s not working.
• Specific Telnyx settings you’re seeing (share the SIP trunk name or relevant config) and I’ll point out what to change. Sources:
