# Firewall Requirements for Direct Media Delivery

Two specific policies **must be put in place** on your network's firewall to ensure you receive all audio on Flowroute calls.

#### SIP Signaling (Call Control)

Allow UDP and TCP traffic over port 5060 from the following server IP addresses:

> [!NOTE]
> **NOTE:** If your system has issues connecting over port **5060**, you can use **5160** as an alternate SIP port.

| Point of Presence (PoP) | SIP Proxy | IP Range |
| --- | --- | --- |
| **United States** |
| US-West-OR | us-west-or.sip.flowroute.com | 34.210.91.112/28 |
| US-East-VA | us-east-va.sip.flowroute.com | 34.226.36.32/28 |
| ***Asia Pacific (in deprecation phase)*** |
| *AP-East-HK* | *ap-east-hk.sip.flowroute.com* | *16.163.86.112/30* |
| *AP-Southeast-SIN* | *ap-southeast-sin.sip.flowroute.com* | *3.0.5.12/30* |
| ***Europe, Middle East, Africa (in deprecation phase)*** |
| *EU-West-LDN* | *eu-west-ldn.sip.flowroute.com* | *3.8.37.20/30* |
| *EU-Central-FRA* | *eu-central-fra.sip.flowroute.com* | *3.71.103.56/30* |
| ***Latin America (in deprecation phase)*** |
| *SA-East-SP* | *sa-east-sp.sip.flowroute.com* | *18.228.70.48/30* |

#### RTP Media (Call Audio)

To reduce latency, Flowroute uses [Direct Media Delivery.](/flowroute-support/docs/what-is-direct-media-delivery) To receive Direct Media, allow UDP packets from **any source IP address** with a destination port within your system's RTP public media port range.

> [!NOTE]
> **NOTE**: RTP media port range varies by phone system.
