Elastic SIP Trunking

What is Twilio Elastic SIP Trunking?

Twilio Elastic SIP Trunking is a cloud-based solution that provides connectivity for IP-based communications infrastructure to connect to the PSTN, for making and receiving telephone calls to the 'rest of the world' via any broadband internet connection. That infrastructure might be a cloud-based communications platform (such as an over the top application, a cloud contact center, or a Cloud PBX service) or it might be premises-based equipment (such as an IP-PBX or a contact center deployment).
