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:

(North America)
FQDN: sip.telnyx.com
Primary: 192.76.120.10 | Secondary: 64.16.250.10
​
(Canada)
FQDN: sip.telnyx.ca
Primary: 192.76.120.31 | Secondary: 64.16.250.13
​
(Europe)
FQDN: sip.telnyx.eu
Primary: 185.246.41.140 | Secondary: 185.246.41.141
​
(Australia)
FQDN: sip.telnyx.com.au
Primary: 103.115.244.145 | Secondary: 103.115.244.146

If you have a firewall configured on your network, you will need to whitelist the following Media IPs.

US/CAN: 64.16.224.0/19 (addresses .0 to .255)
EU: 185.246.41.128/25 (addresses .128 to .255)
AUS: 103.115.244.128/25 (addresses .128 to .255)

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

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