- 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 comming in codecs g729 and g723.

- Other standards codecs like G722, G726, alow, ulow... shall be supported

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

- 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.

- FreePBX shall be used to monitor and configure the system

You are free to specify which distribution and version of FreePBX and 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
