Yes, responsible for this part is the OnlineShop module. It consists of two parts of the web interface integrated with the SoftSwitch's end-users website and the standalone application installed on the server. The module can work with several credit cards processors and also other electronic payment systems like paypal, moneybookers or others (the full list of currently supported systems ).
Customers can sign up online funding their accounts with chosen amount. In a few seconds after the transaction is approved the system sends an email with the account's settings. From this moment the customer can start using the service. Optionally the system can be configured to enable customers to create free accounts (with 0 balance, for example for test).
The accounts can be funded at any moment from the recharge menu on the website.
