those timers are for INVITES sent by kamailio right? starting from t_relay() of the INVITE
what i am looking for is, when i receive an INVITE, i start counting.

the reason behind is, with all the functions involving several sql_xquery() involved to find out where to send the t_relay(),
there will be unforeseen delays which might cause a very high PDD for my callers, i don't want them to wait.

Not only that, but there is also the t_set_fr() module function that lets one change the values of fr_timer and fr_inv_timer dynamically:

   http://kamailio.org/docs/modules/4.1.x/modules/tm.html#tm.f.t_set_fr

However, the arguments seem to be static integers, not string values, so I am not sure the function will take PVs as arguments.  In that light, the AVP approach might make more sense.

Take a look at the following module parameters:

    i would like to have an fr_inv_timer functionality on inbound INVITEs.

    the only way i imagine this to work is to use timer module, set a
    predefined timer value, and when reaching that value after the
    INVITE, execute a ROUTE that
    cancels the callee and sends a 500 or timeout message back to the
    caller.

    problem is, the timeout value for module is static. i need the
    timeout to be dynamic
    for different callers.

    are there any other methods on achieving this?
