It does.  To enforce ACLs on a SIP user or peer or friend, simply use
"permit" and "deny" statements to allow and disallow various IP
addresses or subnets.  Standard practice seems to be to deny everything
first, then specifically allow other IP addresses.

[user]
type=friend
secret=mypassword
host=dynamic
deny=0.0.0.0/0
permit=10.1.2.3
permit=192.168.123.0/24
permit=192.168.222.0/255.255.255.0
