The firewalls in front of our PBX’s are configured to only allow SIP traffic from UK IP addresses, this reduces the attack surface and is usually not an issue as almost all legitimate traffic is from the UK.
As we expand there is greater need for international connections, this is fine if they have a static WAN IP or FQDN, but the more recent requirements are for “home” users with phones on their residential connections where dynamic IPs are the standard.
