I must have misunderstood the module documentation, then.  The 
documentation for the fr_timer section specifically says:

   "Timer which hits if no final reply for a request or ACK for a
    negative INVITE reply arrives (in seconds)."

I understood this literally;  it applies to *final* responses, not 
provisional ones.

But after reading your reply I looked at the "timer-based failover" 
section above it and it says:

   "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. "

So which one is it?  Do provisional responses affect fr_timer expiration 
or not?
