<p class="MsoNormal">One of our larger customers is about to launch a new call center in Malaysia. The connection there is fast, the trace looks surprisingly clean and short, but latency is consistently at 239-245ms. We've never knowingly had a connection
over 130ms. Does anyone have experiences, good or bad, with latency approaching a quarter second? The jitter level seems fine, so I believe they'll just have a delay but decent call quality.
