Choose how inbound calls are answered via `type` + `config` — route to an AI `agent`, a `voicemail` box, an `ivr`, a `sip_forward` endpoint, a `ring_group`, and more — with an optional `fallback_type`, business-hours gating, caller-ID allow/block filtering, a per-route recording override, and an optional per-DID inbound-SMS route. The route shape and any config URLs are safety-validated before persisting. This configures INBOUND handling only; it does not affect outbound calling. Returns the saved route with SIP passwords redacted. Scoped on the `numbers` resource (`numbers:read` or `numbers:write`). ## OpenAPI ````yaml /openapi.yaml put /api/v1/numbers/{phoneNumber}/routing openapi: 3.1.0 info: title: Devotel CPaaS API description: Orbit by Devotel — Communications Platform as a Service API version: 1.0.0 contact: name: Devotel url: https://devotel.io email: support@devotel.io license: name: Proprietary servers: - url: https://api.orbit.devotel.io description: Production security: - Bearer: [] - ApiKey: [] tags: - name: Messages description: >- Send and manage messages across all channels (SMS, WhatsApp, RCS, Email, Viber, etc.) - name: Agents description: AI agent creation, configuration, and execution - name: Voice description: Voice calls, IVR, conferencing, and SIP trunking - name: Webhooks description: Webhook endpoint management and delivery logs - name: Numbers description: Phone number search, provisioning, and configuration - name: Contacts description: Contact management, segmentation, and lifecycle tracking - name: Campaigns description: Marketing campaign orchestration and analytics - name: Flows description: Automation flow builder and execution engine - name: Templates description: Message template management and approval workflows - name: Settings description: Organization, channel, and user preference settings - name: Verify description: OTP generation and verification across channels - name: Push description: Push notification delivery via FCM and APNs - name: Telegram description: >- Telegram bring-your-own-bot channel: connect a bot, verify a chat against the shared sandbox bot, and read unified channel state.
