Answer:

The PSTN uses circuit switching (or switching) for connecting calls (as discussed above). Business VoIP phone systems use packet switching. ... When you dial a number from your VoIP phone, the voice signal is converted into digital data by the IP phone. The digital data is sent to the router.
