- Install asterisk server and configure it to operate with Huawei usb dongles (modems) having prepaid simcards to connect to the GSM network.

- Be able to attach more huawei usb modems to the server if needed. USB hubs will be used to attach the usb modems.

- The server shall be able to terminate voip calls coming in codecs g729

- Send ussd and ivr to each sim card to topup and credit check.

- Add capability of changing IMEI as needed

- Display how much credit is available in each sim card.

- be able to listen to the channels if they are busy.

- If a channel is busy the call shall try automatically the next channel and so on till it finds a free channel.

- Recommend an interface that shall be used to monitor and configure the system.

You are free to specify which distribution and version of Asterisk to be used.

You shall define which model of Huawei usb modems have to be used with asterisk (compatible with Linux and asterisk)

Thank you,

Best regards
