ACC-MIB::accDialOrigIpStatus is a write-only control that manages IP filter table entries in the dial origination database. A network engineer uses this to enable, disable, or remove dial-up routing rules based on IP addresses. Writing the value 'invalid' to this OID removes the entire filter table entry, which is useful when you need to delete an obsolete rule. Example: If you wrote 'invalid' to this OID, the device would delete the filter table row that controlled whether traffic from a specific IP address could trigger an outbound dial connection.
