Er, yes. Of course.
But if it gets
split, rather use nr_inv_timer and fr_inv_timer or
somesuch, to make it a bit more telling. Or use, what is it? A and C?
There is not a 1:1 mapping between the RFC timers and the tm timers.
According to the RFC we should use only fr_inv_timer all the time for
INVITEs :-) (so no fast failover, voicemail a.s.o)
After reading: Isn't fr_timer corresponding to timer B and fr_inv_timer
to C? Which actually would mean that you shouldn't mess with fr_timer
and keep it at 32 seconds and are free to mess with fr_inv_timer but
make it reasonably big?

, which is a more
complete description, including corresponding RFC timer names.
See? ;)
