I'm running a small business by myself and it's imperative to be able to take calls during office hours.
Most of the times I'm at my desk, but during the odd occasions where I have to nip out quickly to the post office or wherever I'd like to still receive the calls to my mobile.
I have 3 voipfone accounts (for 3 entirely different brands and separate businesses). So I have added each of them as a separate sip account with their own extensions.
Secondly, I am aware that mobile calls cost 10p a minute. So I don't really want to make a habit of depending on this so it's going to be for occasional use when I need to pop out to the shops.
Is it possible to add some credit to the voipfone accounts so that it's used as and when needed rather than a monthly credit pack.
