What IPs do I need to whitelist?

Depending on your location, and whether or not you have a firewall/acl configured on your network - please configure the SIP trunk on your voice platform using the following domains:

Media Subnets

US/CAN: 64.16.224.0/19 (addresses .0 to .255)
EU: 185.246.41.128/25 (addresses .128 to .255)

Media Forking IP Subnets

When using the media forking feature Telnyx will send the forked media from an IP address in one of these subnets:

  • stream_type = raw (default)

    • 103.115.244.0/26 (addresses .0 to .63)

    • 185.246.41.0/26 (addresses .0 to .63)

    • 192.76.120.128/26 (addresses .128 to .191)

    • 192.76.120.192/27 (addresses .192 to .223)

  • stream_type = decrypted

    • subnets specified in Media section.

You may need to explicitly open your firewall to allow UDP traffic from these subnets.
