Define happily? Jitter is obviously important, but latency is too. For day-to-day business calls, 250ms is a little high. Both parties will definitely notice it. In my experience you will find yourself talking over one another quite often. Even with 100ms this continues to happen from time to time.
There is no doubt that it can be done, but if your latency ever exceeds 300ms, people tend to get frustrated and it could really start to cause problems. Once your agents realize there is a 250ms latency, and get used to it, it might not be so bad. But personally, it wouldn't be acceptable to me.
