SIP Credentials

Create SIP credential

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.
