SIP Trunking: Powering Seamless Global Connections

SIP trunking replaces traditional phone lines with a virtual connection over the internet, enabling calls through broadband. It connects your internal phone system (PBX/VoIP) to a SIP provider, which routes calls to the regular network—making it simpler and more cost-effective.

​
Supported SIP Providers

Unpod supports multiple providers for inbound and outbound calls:
  • LiveKit – Real-time audio/video calls using virtual members.
  • Vapi – Cloud telephony API for programmatic calls.
  • Daily – Multi-party voice/video with web integrations.
  • Twilio – Global programmable voice for any device.
