I take it this is a network-wide outage as everyone I know on Sipgate cannot make or receive calls, my router is showing that I cannot log on, pinging times out to sipgate.co.uk and there's no secure logon over on their website.

I am with Virgin (Blueyonder) and Sipgate. Once the Sipgate service was great, indistinguishable from landline quality. Recently it has got worse and worse, now it is all but unuseable. I have been bending the ear of a very helpful Frederik at Sipgate, but despite his and his engineers best efforts no improvement. When I ping sipgate with the following command:
ping -l 200 - n 100 sipgate.co.uk
I get a dropout rate of about 6%, often more with average times of about 35ms. Other sites only drop about 1% or less and average response times are sub-20ms. Infact their average response is lower than the sipgate quickest response time.
There does seem to be a virgin-sipgate problem - does anybody know more? I would really love to sort this issue as I have been very happy with Sipgate.
hmmm, the trouble is, when I chase Virgin, they don't bother to reply. I email them via their website contact form, I get an automated acknowledgement email saying they will reply within 48 hours, and then nothing. Twice that has happened. Not very good.
What was the nature of the issue with Plusnet? Any pointers on what I need to be telling Virgin (assuming they are listening...)
Virgin have had some DNS issues of late.
Use text.news.virginmedia.com as the server name.
I take it from being in The Midlands you are xTelewest.
Below are Plusnets replies
The pings are a little misleading for a number of reasons. Pings and VoIP use different protocols and packet headers and are therefor treated differently across our network. The performance of all VoIP traffic on the network should be highly prioritised at all times as per our network management information available on the portal.
If you are getting voice transmission problems you may wish to try using a less data intensive codec within your software or hardware.
If this does not resolve the issue if you can provide us with any specific ports or protocols used by sipgate we can double check that these are being correctly managed by our platform.
I would still strongly suggest playing with the codec a little bit. Having used voice applications for some time, I know a small, barely noticable, sacrifice on the transmission rate can have a huge effect on the over all stability and quality of your VoIP calls.

please confirm whether ports 5004 and 1000 are prioritised as VoIP or provide details as to the reason for deprioritisation.
Thanks, thats exactly the infoI was looking for. Im passing this ticket through to our network engineers to confirm that ports 5004 and 1000 are being prioritised correctly as VoIP service ports or gain information as to why they are being deprioritised.
as VoIP or provide details as to the reason for deprioritisation.
