# Get Firewall IPs

> Get Bland's static SIP signaling and media IP addresses and ports for your region. Use these to configure your firewall and SBC.

### Headers

**authorization** `string` *required*

Your API key for authentication.

### Response

**ip\_addresses** `string[]`

Array of static IP addresses for your region: the two signaling IPs first, then the four media IPs. Allow-list all of them and trust all of them as SIP peers. Calls you send to Bland go to the signaling IPs. Transfers and warm transfer consult calls that Bland sends to your SBC connect from the media IPs. See [Connection Endpoints](https://docs.bland.ai/agents/sip.md#connection-endpoints).

**ports.sip** `string`

SIP signaling port and transport (e.g., `"5061 TLS"`).

**ports.rtp** `string`

RTP media port range (e.g., `"16384-32768 UDP"`).
