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.

Soft phone compatibility with Twilio SIP Domains

For SIP Interfaces, you can use SIP registration to directly register a SIP endpoint/device to both place and receive calls.  Please see the related documentation: https://www.twilio.com/docs/api/twilio-sip/pv-sip-registration

For Elastic SIP Trunking, in order to receive calls, you would need to have a SIP Registar, such as a PBX, or else use a different SIP provider that provides SIP registration. You can then make calls through your Twilio Elastic SIP Trunk's SIP URI, and receive calls from a Twilio number to your SIP Registrar's SIP URI.  This is covered in detail here: https://www.twilio.com/docs/api/sip-trunking/getting-started
