There is also the option to do an asynchronous sleep

We have a buggy endpoint that consistently sends reinvites immediately
following the e2e ACK, and substantially simultaneously with the ACK. It
quite often happens that the re-invite goes out the door before the ACK,
which is of course rejected by the target due to inconsistent state.
We solved this a somewhat nasty hack using just the very technique you
mentioned -- we use the async features of Kamailio to 'delay' all
re-invites about 50 ms. It does solve this problem, if a bit
suboptimally and at the cost of eccentricity and complexity.
