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.
