Which IP addresses should I allow to receive requests related to my traffic from the Vonage API Platform?


  • What IP addresses do I need to add to my firewall?
  • What IP addresses do you use to send requests to my webhook URL?
  • Can I use a firewall and still receive inbound requests from you?
  • I am not receiving callbacks to my HTTP server. Why might this be?
  • What IP addresses do I need to add to my firewall if I'm using Vonage API?


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 that you use. These IP ranges may be used for receiving HTTP callbacks, webhooks, WebSocket connections, SIP & Media signaling.

Traffic from Vonage's API Platform 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.


HTTP Callbacks******


Port: UDP/TCP on 5060, TLS on 5061



Port: All**



Port: All**


SIP Callbacks

*This is IP address/range went live on 27th August 2020 for all products.
**If you are unable to allow all UDP ports, you can alternatively restrict the port range to 10000:50000.
