With the old PSTN networks limited to just voice, and not able to send Data/Voice/Video, a need for a new way has grown. Flexibility is also available with VoIP systems compared to PSTN, so that future technology can be adopted and implemented with less troubles. Now let's look at a few countries and regions.
