How do I know what my monthly charges will be ? If you are thinking of signing up and want to estimate the monthly charge (excluding calls) please use the pricing page. If you have an account and want to know what you will be billed at the end of the month Login to your account. On the menu select Account > Billing > Billing Subscriptions. You will see a list of the subscriptions (look at Active only). In this example the PBX monthly rental is zero and there is DID number rental of £2.99. The total charge on this example will be £2.99 per month. You may also have a balance to be paid for call charges. The current balance can be seen on the billing statement or on the billing statement overview Account > Billing. In this example the current account balance is -£2.60.
