I will venture an opinion about the nature of the traffic. Most (if not
all) residential services, and perhaps SOHO services, whether cable or
DSL are asymmetrical meaning the download throughput is higher, much
higher, than that upload/upstream traffic. VoIP, on the, other hand
requires a symmetrical service for its slice of the throughput pie. The
downstream YouTube video traffic is competing in the downstream 'pipe'
for its slice of the pie with the VoIP traffic. Or vice versa.
A month or two ago, I think John Van O, or perhaps someone else
described how a greedy bandwidth consumer, like maybe YouTube, will grab
the whole through pie leaving very little bandwidth for other consumers.
I don't know what to suggest except to ask who is experiencing the
'choppy' voice traffic. It seems from the YouTube 'solution' that the
problem in the downstream side.
IMHO The problem is in the 'pipe' and not your equipment.
I do not know if there are different grades of service available to SOHO
and residential users.
