Would like to run 100+ Huawei USB sticks as asterisk trunks

You should specify which models of Huawei USB sticks to be used (compatible with asterisk)

The USB modems will be connected to USB hubs (each hub for 10 USB sticks)

A2billing shall be installed and configured,

Add Interface admin for send USSD for selected huawei modem trunk.

Custom a2billing trunk can set credit limit usage per trunk.

IVR functionality.

Codecs g-729 and g-723 shall be installed, because our clients send us calls in codecs g-729 or g-723. Those calls will be connected to GSM network using Huawei USB modems.

Must be able to

Send call

Receive Call

Send USSD

Write all received ussd to a file in form of ussdreccurdate()

must keep track of the stick so if i exchange usb ports we must follow the stick, i suggest we create a db with

trunk_name and imei_number

Once you get this project to work, you must do a writeup of all steps.

I also need a module to change the device IMEI number
