Ina previous post that seems to have died, I was asked if I had
implimented QOS.
I have no ida what QOS is - and would appreciate some clues please - it
was in relation to the fact my Sipgate service is apparently dropping
sound during some calls.
The Internet is not being used when this happens.

Ok thanks. Thast explains what QOS is - but what do I have to impliment
on my machine to avoid dropped speech? I have found QOS in properties
for my LAN settings - it's unticked. Should it be ticked??

You haven't told us what equipment you're using, but if there's an on/off
setting for QoS (small 'o' to be pedantic..!) then yes, it should be on.
Try it and let us know if it makes any difference. FWIW the only time I
ever experience dropped speech is if the person the other end is doing a
heavy download, otherwise it's fine.

Thanks.
I have now 'ticked' the QoS box - I'll let you know the results!
For info - I'm running NTL at 4Mb through a Belkin 54g wireless router
- the Spigate service is connected to the router with a Sipura SPA1001.

Ok, well you shouldn't have any problems with that setup, I've not used
the Belkin router but other stuff I've had from them has always been ok. I
do have a SPA1001 as a spare ATA, I used it on a trip to Germany a few
weeks ago, staying with a friend there, and it worked fine. There are
numerous settings on the SPA that could affect things though, maybe
something there needs adjusting..? In particular are all the regional
settings set to the UK values..?

OT, I know, sorry..........
Any suggested destinations in Germany? Looking to go there next week - Hull
Rotterdam crossing.

I would have to assume so - in particular, the only setting in the
regional tab that refers to the UK is the caller ID method.

Well you can always go and visit Sipgate in Düsseldorf ;-)

It's just dawned on me - the QoS tick box is a part of Win XP - if the
computer is not a part of the sipgate service because it links direct
to the modem / router - what difference would the QoS setting make?
I myself experienced the dropped voice problem today. Is it possible
that a silence in the conversation would cause the drop - much like a
vox control on a noise sensitive microphone?

Silence Suppression is one possible name for it. It will be somewhere in the
config of your VoIP device.

In my Sipura 2000 it's in the line settings - Silence Suppression (an
on/off setting, mine is set OFF) and a threshhold level if it's on
(low/med/high). There's a separate page/setting for each line/account.
I imagine the SPA1001 is similar, I have one but it's not in use at the
moment so I can't check. Make sure S/S is set to OFF.

Thanks Ivor.
I located it - it's a yes / no option ( silence supp enable) - it was
set to No - silence threshold is set to Low.
I'm confused at to what silence actually suppression does - does it
stop silences (i.e generate some noise to keep the line alive) - or
does it stop silences being stopped thereby making the line quiet?
Should I enable the suppression - or not enable the supression but set
the threshold to a high (or low) threshold?

Silence Suppression is, I suspect, the same as Voice
Activity Detection - a way of stopping the transmission of
voice packets with no required content. It is normally used
to reduce bandwidth on a congested link. The receiving end
may insert noise to replace the missing sound, but it's
usually detectable by the listener. SS/VAD may add a few
milliseconds to the delay in processing voice.
Private networks use QoS to prioritise real-time services
such as telephony or video-conferencing. The public
Internet doesn't support QoS even if your Router does.
Packets could be dropped from the queue of any network
Router experiencing congestion, or possibly from the
receiving-end terminal if the delay in transmission is too
great. Using tools such as ping and traceroute might
indicate the problem.
