Creates a project-scoped SIP Credential for a SIP device to register with SignalWire. Use it for a shared or independently managed device; use Create Subscriber SIP credential when the credential belongs to a specific Subscriber. To attach an already-existing resource as the credential’s outbound call handler, use Assign Resource to SIP credential instead.

Permissions

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

Request

This endpoint expects an object.

idstringRequiredformat: "uuid"

The id of the Sip Endpoint

usernamestringRequired

The username of the Sip Endpoint

caller_idstringRequired

The caller ID that will showup when dialing from this Sip Endpoint

send_asstringRequired

The Sip username that will show up on the calle's side. Overrides the username.

cipherslist of enumsRequired

Ciphers that can be enabled for calls on this Sip Endpoint.

Allowed values:

codecslist of enumsRequired

Codecs that can be enabled for calls on this Sip Endpoint.

encryptionenumRequired

The set encryption type on the Sip Endpoint.

Allowed values:

call_handlerenumRequired

Specify how the SIP endpoint will handle outbound calls.

default: The SIP endpoint will pull the outbound policy setting from the SIP Profile Settings. This allows centralized management of outbound call behavior across multiple endpoints from a single configuration.
passthrough: The SIP endpoint will be allowed to dial PSTN numbers. This permits outbound calling to traditional phone numbers without restrictions.
block-pstn: The SIP endpoint will be blocked from dialing PSTN numbers. Use this to restrict the endpoint from initiating calls to the public telephone network.
resource: Outbound calls from this SIP endpoint will dial the specified resource and execute its instructions. Requires setting calling_handler_resource_id to a valid resource. This enables custom call handling workflows for outbound calls.

Allowed values:

calling_handler_resource_idstring or nullRequiredformat: "uuid"

If call_handler is set to resource, this field expects the id of the set resouce. Will be null otherwise.

Response

The request has succeeded.

typestring

A string representation of the type of object this record is.

idstringformat: "uuid"

The unique identifier of the SIP endpoint.

usernamestring

The username for the SIP endpoint.

caller_idstring or null

Friendly Caller ID used as the CNAM when dialing a phone number or the From when dialing another SIP Endpoint.

send_asstring

When dialing a PSTN phone number, you must send it From a number you have purchased or verified. send_as indicates which number this endpoint has set as its origination. random indicates it will randomly choose a purchased or verified number from within the project.

cipherslist of strings

A list of encryption ciphers this endpoint will support.

codecslist of strings

A list of codecs this endpoint will support.

encryptionenum

Whether connections to this endpoint require encryption or if encryption is optional.

Allowed values:

call_handlerenum or null

What type of handler you want to run on inbound calls.

calling_handler_resource_idstring or nullformat: "uuid"

The unique identifier of the calling handler resource.

call_request_urlstring or null

A string representing the LaML URL to access when a call is received. This is only used (and required) when call_handler is set to laml_webhooks.

A string representing the HTTP method to use with call_request_url. Valid values are GET and POST.

Allowed values:

call_fallback_urlstring or null

A string representing the LaML URL to access when the call to call_request_url fails. This is only used (and required) when call_handler is set to laml_webhooks.

call_fallback_methodenum or null

A string representing the HTTP method to use with call_fallback_url. Valid values are GET and POST.

Allowed values:

call_status_callback_urlstring or null

A string representing a URL to send status change messages to. This is only used (and required) when call_handler is set to laml_webhooks.
