douglas,

if you start like this, it does not encourage anyone to help you.

here you cannot blame documentation, but yourself.  you clearly are
lacking any willingness to read existing openser documentation.

tm module README has:

     * fr_timer - this timer is used when no response was received
       yet. If there is no response after fr_timer seconds the
       timer triggers (and failure route will be executed if
       t_on_failure() was called). If a provisional response was
       received, the timer is set to fr_inv_timer for INVITE
       transactions, and RT_T2 for all other transactions. If a
       final reponse is received, the transaction has finished.
     * fr_inv_timer - this timer is used when a provisional
       reponse was received for an INVITE transaction.

if you had read it, you would not have used wrong timer variable.
