I haven't tried VOIP yet, but I am tempted to try the new £19.99 PAYGO package offered by Plus.net.
I currently have an Orchid dialler which intercepts my PSTN calls and routes them depending on the time, date and call type to various providers. This in general works out very cheap for me.
Is there a device which I can use which will route all 01* and 02* calls over VOIP in the evenings or at weekends, but will otherwise pass the calls to my Orchid dialler to make the calls? If not is there a device that can handle the function provided by the Orchid dialler as well?
I can't be bothered trying to train the rest of the family which prefixes to dial for which calls, and I don't fancy having 2 different sets of phones.
