Toucan is (or at least used to be) a Virtual ISP i.e. providing a broadband service through a main ISP. In Toucan's case it's supplied by Tiscali.
Have a look at TalkTalk's International3 package which includes AnyTime local, 01 and 02 phone calls; similar AnyTime free calls to 30 different countries; the BT line rental of £11 a month and free broadband.
Cost is £20.99 a month. See:
Includes a 30 day trial period.
The current prices have altered very slightly in one or two instances and it's slightly cheaper now than my contract.
