  title: Sinch Elastic SIP Trunking Access Control Lists API
  description: The Sinch Elastic SIP Trunking (EST) API enables developers to programmatically create and manage SIP trunks for connecting existing telephony infrastructure to the Sinch network. It provides endpoints for managing SIP endpoints, trunk configurations, and access control lists. The API supports elastic scaling of voice capacity without requiring fixed-capacity commitments, allowing businesses to connect their PBX systems, contact centers, or communication platforms to global PSTN connectivity.
