A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

Twilio's SIP Interfaces vs. Twilio’s Elastic SIP Trunking

Twilio’s SIP Interfaces are a SIP interface to a TwiML application. If you want to send or receive voice traffic to/from Twilio via SIP to interact with your TwiML Application, then SIP Interfaces are right for you. SIP Interfaces also allow you to directly Register your SIP devices to Twilio.

Elastic SIP Trunking provides a streamlined cloud based SIP Trunk at very low prices. It offers both call origination & termination. If you have a need to connect your Business Phone System (PBX) to the PSTN via a SIP Trunk, then Elastic SIP Trunk is right for you.
