ACL order and merging

If you have something like these ACLs (SIP and IP bases combination) you might think nothing will come through. This is not true. 192.168.123.0/24 is allowed to pass.

[acl]
type=acl
contact_deny=0.0.0.0/0.0.0.0
contact_permit=192.168.123.0/24

[acl]
type=acl
deny=0.0.0.0/0.0.0.0

Order of ACLs does not matter.

Hope, someone will find this useful.
