Resource ManagementSIP Addresses

Create SIP address

View as MarkdownOpen in Claude

Creates a standalone SIP Address with a SIP URI, registration password, media and IP-authentication settings, and a resource that handles inbound calls. Use it when an external SIP device or system must register to or dial a dedicated URI. Use Create SIP credential for a device credential managed as a Fabric resource, or Create E911 address for a physical emergency-service location.

Permissions

The API token used to authenticate must have the following scope(s) enabled to make a successful request: Calling, Fax, Messaging, or Video.

Learn more about API scopes.

Authentication

AuthorizationBasic

SignalWire Basic Authentication using Project ID and API Token.

The client sends HTTP requests with the Authorization header containing the word Basic followed by a space and a base64-encoded string of project_id:token. The project ID will be used as the username and the API token as the password.

Example:

Authorization: Basic base64(project_id:token)
