    Anyone been having problems with Sipgate last few days? Several people
    have complained my phone wasn't ringing or they were getting
    unobtainable, and yesterday I wasn't getting any dial tone on Sipgate
    line, though my Voiptalk line was fine on same ATA. I also wasn't able to
    get to any of the Sipgate web sites, though they seem to be OK today.

    I have been having similar problems with Voipfone, I notice that you are
    also on NTL - VirginMedia, could there be a connection?
    I am in the Nottingham area on NTL, and you appear to be in the
    Leicester area though.

    Does VM`s Packet shaping cause issues with Voip?

    Maybe something to consider..

    I had thought that myself, except as I said, my Voiptalk line was OK. I
    am putting some of the problems down to ntl, but it doesn't seem to
    explain the total outage I had on Sipgate last week. Again I couldn't
    even get to any of their web sites. Strange.

    Thanks {{{{{Welcome}}}}}. I know you're on ntl. Are you worried this
    traffic shaping will affect your voip usage?

    Thanks Ivor. Seems to be Ok again now, but the quality of the line seems
    to be less than it was before, several people have commented on
    crackling, gaps in speech, etc. I'm guessing this has something to do
    with ntl's meddling. Strange how my Voiptalk line is still OK though.

    My Voipfone line now seems OK, it seemed to be intermittent when I was
    having problems, this could be why one account seemed OK, but the other
    was having problems.

    I use Sipgate over a Virgin Media ADSL connection (ie former virgin.net
    customer) - does anyone know if they are affected by this "traffic
    shaping" as well?

    Thanks

    Traffic shaping shouldn't have any effect on VOIP if your router gives
    preference to VOIP traffic (QOS)
    A voice channel only uses about 65Kbps each way which means even on a
    2MB connection cut back to 1Mb you still have plenty of spare bandwidth
    besides, AFAIK it's only the down stream which is "shaped" and on most
    broadband connections it's upstream which is the limiting factor.

    I'm on xTelewest 4mbit broadband, this will drop to 2mbit if I get
    traffic shaped, I don't see that this will be a problem for me, at the
    moment I just run two lines both with G711 codec, 2mbit is still more
    than enough for download, with my upload limited to 192Kb if I am
    shaped.

    The upload speed that is being shaped too:
    http://abcde.co.uk/virginmedia/stm.html

    I've not hit a point yet to become shaped, so I will have to wait and
    see. It may mean using a different codec if it becomes a problem, not
    that I really want to switch away from G711.

    Not sure, with Virgin ADSL they have a Fair Use cap set at 40Gb (at
    least they did a couple of weeks back).

    Although uploads do not count towards the threshholds before STM is
    introduced, VM will reduce your upload speed if STM is triggered.

    Unfortunately, mine doesn't, so any reduction might be problematic.

    > A voice channel only uses about 65Kbps


    That depends on the codec you're using

    > AFAIK it's only the down stream which is "shaped" and on most broadband connections it's upstream which is the limiting factor


    As Jono said, they're also reducing the upload if you get hit, and 128kb
    (on the 2Mb package) doesn't leave much headroom if you want to do
    something else whilst you use the phone.

    Indeed.
    I hadn't realised they were hitting the up-stream as well as the down.

    You can only effectively traffic shape/apply QoS to data leaving your home
    network out to the big bad Internet (Virgin, et al. can shape their entire
    network as they control entry and exit) however, as incoming is usually
    a lot faster than outgoing, you can do quite effective traffic shaping/QoS
    yourself if you have a good router/firewall device. It will never be 100%
    perfect, but for the most part it will be perfectly acceptable. Different
    devices work in different ways, but if you can give a high priority to
    outgoing SIP and RTP packets (or IAX if you're using an IAX service),
    then you'll be well on your way to having an acceptable service -
    certianly for a home user. Even on a 128Kbps outgoing line, you'll be
    able to carry one G711 call (which needs 80Kbps each way)

    However I've no idea what consumer devices are good these days - obviously
    with cable you need one with 2 Ethernet ports - one on the WAN side and
    one on the LAN side. I've used Drayteks successfully in the past - 2900's
    for such things, but they're not cheap. (And I'm not a great fan of them
    these days - don't try their VPN facilities over anything other than a
    512Kbps line!)

    I have successfully handled 4 simultaneous SIP calls at G711 using a
    ADSL-MAX line (448Kbps upstream) while still having acceptable internet
    access, although I don't do things like p2p file-sharing, and I have
    a decent ISP (Zen).

    Which is a royal pain, since the QoS relies on you setting your
    available upstream bandwidth, which will drop.

    I'd be a lot happier if it was just the downstream bandwidth that dropped.
