There are two methods by which knowledge is transformed to be transmitted over the web:
- Originating from a PSTN: Name visitors originating from a standard or legacy cellphone sign (analog) is remodeled right into a digitized sign. That digital sign is compressed utilizing a “codec” and damaged right into a sequence of “knowledge packets,” encrypted for transmission, after which transferred throughout an IP community.
- Originating from an IP community: When calls originate from an IP community, gateways work in reverse by decompressing the information packets into digital alerts. Then the alerts are transformed into analog alerts and despatched throughout the PSTN.
