Internet platform for the sale of 8800 numbers, sip telephony, virtual PBX, multi-channel number

           The service is based on the principle of "one page", that is, the user goes through all the stages of choosing a product and making a purchase without reloading the page. This service has 4 sections: purchase of 800 and Moscow city numbers, SIP telephony, virtual PBX, multi-channel number. Getting into each of the sections, the user must go through all 6 stages to purchase a number or other service. The registrar block is a module that allows the client (the site user) to create order parameters by means of selecting these parameters at separate steps. The transition between steps and other functional elements work without reloading the page (AJAX requests are used). The transition through the steps of the order is carried out only one step ahead (only the next step). The API is used to get separate information that is provided to the user. After successful collection of information for the order at all steps, the process ends with the final sending of all received data.
          Users can choose not just numbers, but also sort by their "beauty", choosing between simple, silver and gold. Next, the user selects the minute packages. Additional options, at this step the customer can add/remove additional options to the order. At the same time, the cost of the order may change, both one-time and monthly. The cost of additional options depends on the tariff plan chosen by the client. The Continue Connection button is located at the bottom of the block to proceed to the next step.
          Equipment selection, at this step, the user can select a set of equipment in the order. The list of equipment is displayed one item per line. Next to each piece of equipment there is a button to the cart, which allows you to add this equipment to the order in the specified quantity. If necessary, pagination is displayed to split the list of equipment by pages.By clicking on the add to cart button, the customer adds the selected equipment to the cart in the specified quantity. The customer can delete the selected equipment in the basket by clicking on the cross next to its name. When adding/removing/changing the amount of equipment, the total amount in the basket must be recalculated.

          The project was developed for the Moscow holding CJSC Best-Telecom
