## Create a SIP profile

**post** `/v3/sip-profiles`

## SIP configuration

Your Linq representative provides the signaling and media IP ranges and
ports to allow through your firewall during onboarding.

Set `primary_uri` to your endpoint as scheme + host — `sips:` for TLS or
`sip:` for UDP, with no user part (we add it). Each call arrives at your
endpoint as:

```
sip:<called-number>@<your-host>
```

so you can route on the dialed number. The caller's number is in the
`From` header in E.164.

---

Create a SIP routing profile for your inbound calls, then assign it to a
phone number to start routing calls to its SIP URI.

### Body Parameters

- `name: string`

- `primary_uri: string`

  Your SIP endpoint as scheme + host, e.g. `sips:sip.partner.example`. Must start with `sip:` (UDP) or `sips:` (TLS) — the scheme sets the transport. Do not include a user part: we set it to the called number on each call (`sip:<called-number>@<your-host>`). A bare host with no scheme is rejected.

- `backup_uri: optional string`

  Optional failover SIP URI

### Returns

- `SipProfile object { id, assigned_number_count, created_at, 5 more }`

  - `id: string`

    Unique identifier for the SIP profile

  - `assigned_number_count: number`

    How many phone numbers reference this profile

  - `created_at: string`

  - `name: string`

    Human-readable name

  - `primary_uri: string`

    Your SIP endpoint as scheme + host (`sip:` UDP / `sips:` TLS); no user part — we set it to the called number on each call.

  - `updated_at: string`

  - `version: number`

    Monotonic version, incremented on each update

  - `backup_uri: optional string`

    Optional failover SIP URI. Null when unset.

### Example

```http
curl https://api.linqapp.com/api/partner/v3/sip-profiles \
