# GSM Hardware Parameter Retrieval

To ensure perfect auditing parity across billing records, the framework reads hardware strings directly from physical gateway modems. **Asterisk 2** queries hardware string outputs to record unique cellular identity markers.

## Hardware Identity Scraping Topology

The chart below details the scheduled pipeline extracting hardware strings from physical telecom modules:

## Technical Auditing Parameters

### 1. Mapped `IMEI` Register Strings
International Mobile Equipment Identity variables track original hardware cards. This lets application controllers detect undocumented hardware modem swaps immediately across distributed server setups.

### 2. Mapped `IMSI` Register Strings
International Mobile Subscriber Identity attributes identify physical cellular accounts. Tracking this string completely blocks billing platforms from mixing call metrics during shared gateway routing assignments.
