In 1.11 you'll want to use $T_fr_timeout in your script to change it.

By default we set:

modparam("tm", "fr_timeout", 5)
modparam("tm", "fr_inv_timeout", 5)

You can dynamically change these values in your script.  For example we set fr_timeout 10 (seconds) on an initial INVITE and then after we receive progress we change it back to 5 for the remainder of the call setup.  

Also don't forget that you can litter your script with xlog's to output the current values of the two timers.

    xlog("Current fr-timer:  $T_fr_timeout");
    xlog("Current fr-invite-timer: $T_fr_inv_timeout");

I found that it was informative to see when/where in the scripts the timeout value was set.  I don't think being able to dynamically change these timers in script was available prior to 1.11  

Hope that helps.

Cheers,
