Configure Firewall to work with Ringotel
Ringotel mitigates security risks by communicating with your PBX only from the trusted networks. It works as a secure VoIP tunnel that routes voice traffic form remote users to the connected PBX(s).
Ringotel’s unique architecture provides a number of advantages. You can find them on our dedicated How Ringotel Works web page.
Configure Firewall between the PBX and a Ringotel server
Please configure your Firewall/NAT to allow incoming traffic from the Ringotel IP(s) to the SIP (TCP/UDP) and RTP (UDP) ports configured on your PBX. Choose the IP address of the region which you configure when creating an organization in your Ringotel Shell portal (it is not required to white-list all regions).

For FusionPBX: Do not add Ringotel IP addresses to your FusionPBX ACL as this may cause outbound calls to not work. For your phone system, Ringotel works like any other SIP endpoint, such as IP phone and softphone.
Note: It is not required to white-list the full list of IPs. Only white-list the regions where you create organisations / users.
This list of IP addresses and regions is occasionally updated.
