Being the end of my billing month (fusion) and being on 96% of my datacap, I thought I'd overrun it to see what sort of speed I'd get.

I'm over my cap I'm quite surprised that my vfx line is unusable since my speed has been capped.  As the VFX data is considered Local data and isn't charged, shouldn't this data still run at full speed so i can use my phone?

Basically I'm without a phone till tomorrow.

That should not happen.  Log a help desk request (or Phil will pick it up from here unless he is away for the weekend.  But when your speed is capped, there should still be enough bandwidth available for VFX.

What device are you using? Some seem to be configured to use G711 codec as default. If your speed is throttled, then there won't be enough bandwidth for this codec. G729 codec will work ok on a throttled connection, but will also struggle if any other Internet activity is going on at same time.

What kind of phone are you calling for the test?... when calling Vodafone mobiles the call will be forced to G711, which may be a problem as mentioned above.

I experienced the same problem yesterday. I would have thought VFX traffic wouldn't be subject to any speed restriction.

[edit]I should clarify, VFX still worked but the quality was terrible when I was checking voice messages.[/edit]

Vodafone have fixed this issue and no longer require g711

Slingshot manage to cap you and leave a working italk service, g.711 and multiple calls without affecting the internet speed - 8k/sec solid despite 3 phonecalls going on. Perfect voice quality.

Perhaps xnet could do it the same way where the voip is immune from the throttle. I certainly dont like the idea of having to resort to an aweful codec at the end of a month when not wanting to put more data on.

It shouldn't have happened, Log a fault as your modem/router should still be syncing at the higher speed and the cap should be in the WxC network.

THis does not normaly happen

are those experiencing the problem set up with any kind of QoS?

because "allocated VoIP bandwidth" doesnt count for anything if the router lets the PC's soak up the remaining 64kbps.

The connection is not limited to 64kbps, the internet is.
That should leave 3-7Mbps available for VFX traffic.

I'm not convinced that's correct, 64k is ample for voice calls and so the entire connection is restricted to that number for that reason. Happy to be proven wrong though.

Yep have been away from the PC for a few days, made a point of it actually :),


If you go over the data cap you will get restricted bandwidth, a G729 shoukd be okay a G711 will be effected, I will need to take a look at this as otherwise if we increase it to much we will get blamed for allowing to much bandwidth, We may have some other options but will need to take a look at some options first.

That would be great if VFX traffic can be made immune to bandwidth throttle. Can be a sticking point for families with teens & being scared of a big data bill. Although G729 should be ok, it is not always an option; i.e. some carries don't accepted it (though sounds like Vodafone are sweet now), sending / receiving a fax, two VFX lines in use, and some phones & setup do need G711 for acceptable voice quality.
Cheers

I hope this can be sorted so that overgage on data cap -> throttled internet does not affect VoIP. Call quality and the phone service should be 'sacrosanct' and IMHO separate from the internet side of things. Afterall, the service is advertised as a replacement for the traditional POTS system (although I guess if you didn't pay your phone bill in the old days, you pretty soon got cut off altogether, no G729 - just gone!).

Further (and without obviously being privvy to the economics of this from Xnet's POV) the amount of data used by a VoIP call is surely negligible, and more than compensated by the 0.05 cent per minute charge, which adds up to a gigabyte after 20 minutes (at $1 per GB on the 'unlimited' rates). I'm guessing 20 minutes does not equal 1GB of data (but happy to be proved wrong!). I appreciate there are VFX maintenance costs built into this pricing model, however.

To conclude - can it be said that you are 'paying for more data / bandwidth' as you go by using VFX, hence should be not subject to the data cap for VoIP?

ps as I am happily on the 'unlimited' plan, the above doesn't apply - but it is a valide question and potential problem for those on capped plans, and relying on their phone to 'be there'.

VFX traffic on our network is free and does not effect your data cap, good points raised questions though also by CB, but as I said in the previous post we will need to look at this, the issue will be how much bandwidth allowed and how we can controll it,
