    Just wondering what is the sucess like using sipgate on uni networks -
    appreciate bandswith can be an issue, lets assume using the GSM Codec where

    At home I have had to use port forwarding because I don't understand STUN
    (or more to the point am obviously stupid because I can't find where it is
    in XTN lite - pointers greatfully accepted).

    Am I right in thinking that using STUN it is no problem only having a
    Private IP address and that no port forwarding is needed. If this is the
    case do the two ports (can't remembe off the top of my head) just have to be
    'not closed' on the firewall \ router?

    Sorry i'm not an expert on this stuff but want to know more.

    Incidentally it very very much relates to my university cource, plus I want
    to be a bit clever in routing phone calls.

    Also - is it just me that can't do a call transfer on sipgate? The other
    useful feature would be the ability to use call divert functions.

    Many thanks for any pointers,

    I think X-Ten Lite doesn't support it. Try buying it :)

    I've not opened any ports on the firewall, nor made changes to either of
    my routers wrt port forwarding, but it didn't seem that difficult to set
    up when I looked at it a few weeks ago. Get in touch and compare notes?

  3. Why do you assume this? JANET has a heck of a lot of bandwidth, my
    place of work can easily support a video conference that *required* a
    10Mbit connection, so VoIP should not be an issue at all! Of course
    your uni/college might be connected to JANET at a slower speed, but I
    wouldn't know.
    Well, you'd need to ask your computer support people whether they
    allow VoIP traffic through the border firewall. Also, if it relates to
    your course, I can't really see a problem - but again check with your
    AUP (acceptable use policy) of the network.

    Good luck :)

    when i was in halls in 98 we could network up to janet with our pcs in our
    rooms. we could download files at speeds of 35kb/sec, they capped each
    download to that but you could do multiple downloads at that speed. we had
    multiple t3 connections back then. god knows what speed they go at now.

    Indeed the main links are huge, but some people have reported problems when
    everyone in their block or whatever is downloading - my point was really to
    discount the bandwith issues if there happened to be any in any instance,
    but on the STUN \ not having a public ip address or the ability to change
    router settings to use port forwarding.

    There is a lot missing off that though - where is the University of
    Manchester? Last time I checked NNW ran through them not Warrington and
    Manchester was throwing so much bandwidth at JaNET that the western
    backbones were upgraded a couple of years ago just so they could keep
    That will be down to whoever is operating the individual network for the
    hall of residence. JANET provides the backbone bandwidth and a connection
    into the network. The computing department of each university is
    responsible for the what they do on campus. Some of them will run fiber
    to halls whilst others will use slower links and even down to 10 meg hubs
    depending on how old or stingy they are being.

    I had the fun of being in halls that didn't have any sort of data running
    to them. The best we had was a few phoneboxes in the middle of the
    complex (Norfolk Park, Sheffield Hallam incase anyone is familiar).

    So from experience does that mean that sipgate will work with a connection
    in halls of residence?

  8. So from experience does that mean that sipgate will work with a connection
    My experience with my daughter's halls of residence connection is that
    Internet access is via a proxy and it's so locked down that we can't
    get MSN messenger voice connections, or Skype to work at all. Dunno
    about sipgate, but I suspect it'd be similarly hampered.

    I guess it all comes down to the particular establishment, but these
    days I'd expect them all to be pretty rigorous (limiting).

    i had the same proxy probs back then. not everything worked and it was quite
    annoying at times, the basics worked but not the nice stuff. wasnt as bad as
    the uni computer labs running windows 3.1 though in 1999!
