5.3 VoIP Trunking Overview
VoIP trunking connects an IP network (like the Internet) and the Public Switched Telephone Network (PSTN).
PSTN includes the world’s circuit-switched telephone network which is composed of fixed and mobile
telephones. VoIP trunking allows you to create VoIP links which PSTN (Public Switched Telephone Network)
callers can use to:
• Make phone calls via the Internet - Make a PSTN call to the P-2302HWUDL-P1 and it forwards the call to any
SIP based VoIP phone. In the example below, we call the P-2302HWUDL-P1 (
B
) from a regular phone (
A
), the
P-2302HWUDL-P1 then forwards the call to a VoIP phone (
C
).
• Save on long distance calls - The P-2302HWUDL-P1 creates a VoIP link which can be used to connect to a
PSTN phone in another country, province, region and so on. Below is an example of a VoIP trunking call.
