Note that as you say "a transaction timer indicates how much to wait for a 
transaction", but OpenSer does various transactions in case of DNS failover, 
so IMHO the parameter meaning and behaviour is correct.

Maybe a new parameter:
   modparam("tm", "fr_timer_max", X)
?

This parameter could set the total time for the N possible transactions 
generated by OpenSer. Example:

  modparam("tm", "fr_timer", 10)
  modparam("tm", "fr_timer_max", 20)  ; So just 2 DNS failover tries
