the FR receive the accounting request:

rad_recv: Accounting-Request packet from host 172.26.0.8 port 1645, id=186, length=399
        User-Name = "0873000001"
        NAS-IP-Address = 0.0.0.0
        Service-Type = Dialout-Framed-User
        Class = 0x436c6173733d333030
        Cisco-AVPair = "h323-incoming-conf-id=b97aff16 c99911dd 8125d127 98296413 "
        h323-conf-id = "h323-conf-id=b97aff16 c99911dd 8125d127 98296413 "
        h323-setup-time = "h323-setup-time= 4:43:17.000 UTC Mon Dec 15 2008"
        h323-connect-time = "h323-connect-time= 4:43:21.000 UTC Mon Dec 15 2008"
        h323-call-type = "h323-call-type=VOIP"
        Called-Station-Id = "0873000012"
        Calling-Station-Id = "0873000001"
        Acct-Status-Type = Start
        Acct-Session-Id = "b97aff16 c99911dd 8125d127 98296413 "
        Event-Timestamp = "Dec 15 2008 11:43:21 ICT"
        NAS-Port-Type = Ethernet

then FR should send accounting respond :

h323-credit-amount=customer balance at the time of authentication

h323-return-code=0(accept)/2(reject)

h323-billing-model=2

Sending Accounting-Response of id 192 to 172.26.0.8 port 1645

can the FR do that? if yes, where should i edit

if i want to send response to NAS i should add the attribute in the attrs.accounting-response :

h323-credit-amount=* ANY

h323-return-code=* ANY

h323-billing-model=* ANY

i check the attrs.accounting-reponse:

#
#       Configuration file for the rlm_attr_filter module.
#       Please see rlm_attr_filter(5) manpage for more information.
#
#       $Id$
#
#       This configuration file is used to remove almost all of the attributes
#       From an Accounting-Response message. The RFC's say that an
#       Accounting-Response packet can contain only a few attributes.
#       We enforce that here.
#
DEFAULT
        Vendor-Specific =* ANY,
        Message-Authenticator =* ANY,
        Proxy-State =* ANY,

i read the man unlang times but cannot figure out how to use it

could you give the example for specific case such as Access Reject/ update the Access Reject/Accept
