For those that have phoneline from BT on can now switch line rental as well as calls to other companies, BT no longer has monopoly try The Phone Coop. So if one uses a BT reseller for line rental, calls (CPS) and broadband one is not as locked in as with Telewest cable. Though The Phone Coop is usefull for those on Cable/Telwest phone to get 4.7p capped under hour calls on an evening rather than default 3p/min on Telewest.
Pre-dial access numbers from UKFSN (using Justdial) are another option for international calls that raises a little money for free software but the irony of it is web interface to serve up from Just Dial's web database for actual call routing prices uses Microsoft web products.
There are others that are probably cheaper using pre-dial numbers from a company called Connect Telecom UK Ltd (Finarea SA) under brandnames Phonecheap, 0844calls, Discountdial, Dialaround, Telediscount, Telesavers, Telestunt and others (note they offer different rates via each but rather than having to check out each one use a comparison site). For UK landline numbers at 0.5p per minute try 0844 205 05 05 or at 1p per minute 0844 861 21 21 or UK mobiles at 6p per minute try 0844 754 41 41. The disadvantage of this is that one gets charged for time the call ring even if not answered which is often the minimum charge. Also for some it may be an advantage and other a disadvantage that the number acually dialed does not show on an itemised the bill, which now-a-days can be downloaded and imported into a spreadsheet. One could even enforce use of these numbers for international and mobile calls by barring them which is free if you use the Phone Coop
Also the same Connect Telecom / Finarea SA is behind a slightly different method that is maybe more suitable for mobiles: 18185, TopUpDiscount and TeleTop, so more rates to compare but do take into account the costs call to London number to access, as well as there system. Also this method makes more even sense if one has an unlimited call package.
I still recommend you switch your line rental from BT to The Phone Coop (and apply for a share in The Phone Coop) but on either look at using these prefix numbers for each call where saves money which in most cases will.
Be carefull of going on quoted price with prepay services especially cards watch out for hidden costs such as connection fees, and also for expiry dates. Often one can get messed around with bad customer service especially if the company starts to fail. I ended up paying a lot more than led to believe in there adverts with SwiftCall so avoid them.
There are many providers of directory enquiries one of the cheapest is provided by the Phone Coop 118114, it shows the power of advertising that many people use the more expensive numbers advertised on TV
Also you can get internet access with these companies, but see another net access page.
