Tutorials: Adding Access Control List (ACL) in the Voxtelesys Portal: Registration
Required Access: Voxtelesys Portal
You can lock down your Registration to a single IP address in our portal to prevent your credentials from being used elsewhere. This is an extra security feature we offer. This is best for Static IP addresses and will make it so that your registration attempts can only come from that IP listed.
