Since the last posting, I've had some worthwhile experiences with my VOIP.First, the HT286 worked perfectly.  I'm working toward switching over my home phone services, too.  I picked up the Gransdstream HandyTone 503, which provides 2 phone lines for 2 SIP trunks. The first thing I noticed during the echo test, was that the latency was much lower then the 286's.  That joy was short-lived, though.  My outgoing sound path started having lots of jitter.  The incoming sound was perfectly clear, but people would tell me my voice was breaking up.  I could recreate this in the echo test.  After a minute or two, the sound quality was pitiful. Basically, it was a QOS problem.  I tried setting the QOS properties on the 503, but it didn't help.  Even though my router had VOIP QOS settings, they didn't seem to work.  I replaced the stock firmware on my wireless router with dd-wrt, configured QOS, and the problem disappeared!  I even performed a bandwidth download/upload test, and there was no loss of quality. I'll be porting my home phone number to my SIP trunk provider real soon:) Eric
