Has anyone had any success using the voip.co.uk service in conjunction
with a NTL residential Internet account?
I am using a Grandstream HandyTone-486 ATA which connects ok to the
voip.co.uk SIP server. I am able to receive calls from PSTN lines but
when I try to call a telephone number, I hear the line ringing and
then when the person I am calling picks up their phone, the line
immediately drops. It has been like this ever since I signed up last
weekend.
I have heard only positive things so far about voip.co.uk on this and
other forums so am beginning to wonder if it is anything to do with my
NTL Internet connection. Does anyone know if NTL are blocking any
ports which could be causing my problem. Or could anyone suggest any
other possible causes?

What have voip.co.uk said in response to the ticket you've raised?

I use tem on Telewest with no issues, one thing I did have to do was
place my ATA in the DMZ on my router.

Hi,
I'm not using a router, My Grandstream ATA is connected directly to
my cable modem,

Your ATA has a router built in <http://www.grandstream.com/y-ht486.htm>
DMZ is "De-militarized Zone". In your case, no use looking at DMZ as
your ATA is already in the best position in your network.
Have you tried any alternative service providers? If you set yourself
up with a well known free provider, you could establish (for the most
part) where your problem may lie - ring a freephone number to check
outbound & call yourself on the geo number to test inbound.

Demilitarized Zone
The DMZ feature allows you to forward all incoming ports to one
device/PC.

Hello,
Yes, as an experiment, I tried using voipcheap with my ATA and I was
able to place an outgoing call successfully. With voip.co.uk I can
only receive calls. When I make an outgoing call with voip.co.uk, the
connection drops almost immediately as soon as the perosn being called
answers their phone, every time without exception so far.
After 10 days from signing up, I am still trying to get them to sort
out this problem and they have yet to offer a solution (if one
exists).
It happens that Steve in Herts formulated :

Bizarre.
They were responsive the one time I had a technical issue.
If anything's likely to be an issue, it's inbound calls usually.
As a matter of interest, if you log in to your account & choose the
link "Your SIP Accounts", does anything look out of the ordinary?
What servers are you using for voip.co.uk? I'm using proxy.voip.co.uk

Hi Jono,
When I log into my voip.co.uk account, it shows the correct IP
address. Everything looks ok as far as I can tell.
voip.co.uk support normally reply to email messages promptly but in my
case, it seems to be taking ages to sort out this problem. I am
coming to the conclusion that there is nothing wrong at my end given
the fact that I have been able to use another VoIP service using my
ATA and also because voip.co.uk support have told me that my ATA is
set up correctly for their service. I can't think what else could be
wrong but then again, I'm not all that knowledgeable about the finer
details of VoIP and SIP.
I am using proxy.voip.co.uk for both "SIP server" and "Outbound Proxy"
as listed in the config of my ATA (Grandstream HandyTone-486).
Voip.co.uk - using with NTL 
Linear Mode
