Alex,
I read about INVITE server transactions in rfc3261 and looks like the
transaction can stay in Completed state (i.e, absorbing 200 OKs) at
least 32 seconds. It means that the via branch hash table must in a
busy proxy be quite large. Since the same info must be available
somewhere in the depths of tm module, would it be better if someone
with tm knowledge would write a function to access it?
