The differences
between SIP VoIP and PSTN |
|
|
|
| |
Users make phone calls by PSTN for a long
time. The voice quality is good, but the expense is much
high. Because VoIP is digital, it may offer features and
services that are not available with a traditional phone.
|
|
|
|
|
|
| |
VoIP allows you to make telephone calls using
a computer network, over a data network like the Internet.
VoIP converts the voice signal from your telephone into
a digital signal that travels over the internet then converts
it back at the other end so you can speak to anyone with
a regular phone number. |
