It's already mentioned on a couple of threads, but fortunately Skype don't seem to have read them yet, so keep your head down

Try Enlinea instead of CBW, to save 2c per minute. Call2 about the same, but I haven't tried it

edit - I see Enlinea is now 4c or 5c. Nikotel appears to be 2c, but I haven't tried it yet.

But I wonder if you have had any problems with actually doing the dialling when going via the Skype forwarding like this, as there seem to be issues about recognising DTMF ? You probably need to program the destination in advance, such as via the wap/gprs method that DRN discovered

Voipfone and Mywebcalls are cheaper still, about 6c or 5c overall, but you need another callback trigger method like wap/gprs or sms as their trigger portal numbers need caller ID**. about one in ten of connected calls seem to have a bit of delay, and once in a while the quality is unusable - this could be down to any link in the chain

But the cheapest of all would be to use Voxalot or similar callback with VoIP providers with free or per connection calls, like several Australian ones, Finarea companies or an offer with Babble that I haven't tried yet. Some won't do both legs of the call though; they connect but no audio.

So 2c per minute seems to be the minimum possible.

nb using callthrough numbers (to reduce the price of calls to most other countries' mobiles) seems a bit problematic when used with skype forwarding at the moment as (see also above) the DTMF codes don't seem to be relayed so the destination can't be dialled. If this could be got to work then it might be possible to call much of the world for about 10 to 15c

** although you can set Mywebcalls to recognise one caller ID and callback to another number ... but then, again the trouble about DTMF ...
