That will happen only if your CPUs are already maxed out.
Under ideal conditions, the default should work fine. But if you are
dealing with network jitter and several clients pumping traffic at
different rates, for a short period of time all the workers will be busy
while new SIP messages will pile up and the default queue will not be able
to hold all of them.
An increased UDP queue will hold all the SIP messages giving time the
workers to consume them.
The idea is that you have the UDP queue empty all most of the time, and
only when there’s a short temporary traffic burst, it will come to the
rescue.
If the UDP queue of full most of the time, then increasing it obviously
won’t help. The increased UDP queue works only for coping with short
traffic bursts.

Sure, but if you're blowing through the default,
that means you're not
consistently coping with the load due to some other factors. Does it not
follow that enlarging the queue will just give you more backlog without
increasing throughput?

The default queue I believe is about 2MB. Not very hard to exceed that
queue while
still having a good amount of CPU/processor available.
