No.

I had a lot of trouble with talk talk so switched to pipex and have had no trouble at all with any p2p and also it is quicker.

TalkTalk + Tiscali connect using B.T. phone lines & all of them Shape,Block,control,& filter P2P traffic Whatever they have said on the phone
is crap, ring them again & ask for that in writing, then see what they say.
Peace.

Will do, again as someone has previously mentioned there is a problem with Talktalk customer service the person you are speaking to is English is not their 1st language.
