Access control list can allow or deny ranges of IP addresses. There are several purposes for using the ACL.
- The main purpose is for your carriers ip addresses.
- Be careful with what and how you use ACL.
- Most common mistakes result in calls not working between extensions and other undesirable results.
- Be sure to keep Domains access control to default deny.
- Do not put your public ip or phone IP addresses in the domains access control list.
- Don’t supply both the domain and the cidr on the same node.
- If adding a single IP address to the CIDR field make sure to add /32 on the end of the IP address.
Access Control Example¶
