Ports
Outbound
All inbound and outbound traffic requires TCP port 443 (HTTPS). Responses are sent to a range of ephemeral ports. This requirement applies to:
- VCC traffic, regardless of whether you use URL or IP allowlisting
- VCC APIs
- WebRTC traffic (see WebRTC sections later in this page for information about other ports required for WebRTC traffic)
- All other third-party traffic (Amplitude, Cloudfront, and NewRelic)
SFTP access to call recordings requires TCP port 22.
Inbound
All inbound traffic requires access to destination TCP port 443 (HTTPS) on our servers to establish a connection. Responses are sent to a range of ephemeral ports.
