I just wanted to say that Voipfone's customer support department is excellent. Not only do they exist, but they are available just as they say they are - 24 hours a day, 7 days a week.
Spent about 5 hours on Sunday to-ing and fro-ing with the support personnel by email to sort a problem and it was great not having to wait until normal business hours on Monday.
So, Daragh, don't worry - if you need their support then you'll find the Voipfone staff ready and waiting for your email.
They can be contacted at
support@voipfone.co.uk
After the problems I've had, I certainly give them 98/99 points out of 100!
By the way, when you start analysing Skype prices (I'm with them as well) you'll find that they aren't always cheaper than Voipfone. Don't forget that Skype charge per minute or part thereof whereas Voipfone are clever - these guys can count in seconds!!!
