Question

What IP addresses do I need to add to my firewall if I'm using Vonage Communication APIs and SIP Trunking?

Applies To

• Communication APIs
• SIP Trunking
• IP Addresses
• Firewall Settings

Answer

If your platform restricts the inbound traffic it can receive using IP address ranges (typically via firewalls), you'll need to add the following IP addresses to your allow lists, depending on the API products you use. These IP ranges may be used for receiving HTTP callbacks, webhooks, WebSocket connections, SIP, and RTP/Media.

Vonage's API platform traffic might come from any of the IP addresses included in the referenced subnets. For all of our non-Voice products, the HTTP Callbacks IP ranges will be sufficient.

All Services

Any function mentioned above could use the following IP ranges (Callbacks, SIP, RTP, etc). Please allow the following ranges to enable seamless communication with Vonage APIs.

*These IP ranges were added on 8th April 2022. It is recommended that they be added to your allow lists as soon as possible.

**If you cannot allow all UDP ports, you can alternatively restrict the port range to 10000:50000.
