## Update a SIP profile

**put** `/v3/sip-profiles/{sipProfileId}`

Update a SIP profile. Only the fields you send are changed; omitted
fields keep their current value. Set `backup_uri` to an empty string to
clear it.

### Path Parameters

- `sipProfileId: string`

### Body Parameters

- `backup_uri: optional string`

  Set to "" to clear the backup URI.

- `name: optional string`

- `primary_uri: optional string`

### 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.
