    hello all,

    i have configured 2 cisco 2600 router as voip gateway. on legs 1 and
    4 ...i m simply using phones with fxs.

    both the routers are connected with IAS w2k3 radius ...and i m
    successfully able to do accounting,

    now i m very confused with the idea of authentication.

    what i want is ..... if the calling no as username is not present in
    Radius' database then router should not proceed for dialing. i saw a
    similar question on this forum,,, with the solution of AAA
    pre-authenetication on the grounds of dnis or clid, but i m thinking
    (may be i m wrong) its just for isdn. so whats for fxs, simple
    telephony ???

    also,

    i m bearing in mind that before dialing from nas , nas would ask
    access-request to radius with calling no attribute present.

    i would have configured the username in active directory which will be
    registered with IAS radius. if IAS is able to find that username in
    active directory , would it reply access-accept to the nas.?? and nas
    will continue for calling !

    on NAS i will be just giving ,,

    aaa new-model
    aaa authentication login h323 group radius



    its not working at my end ...nas is not sending authentication logs as
    im expecting.
    now what should i do..whats the way out ???


    thanks indeed,
