It converts voice into hundreds of data packets, which then travel over an IP network. These packets follow the same internet infrastructure as other data, such as email and general web traffic. The VoIP system routes them through the available internet bandwidth using codecs (to compress and decompress data). This way, information is transmitted at high speeds, with minimal data loss and maximum accuracy.\u00a0<\/p><p>However, PSTN is an analogue phone system based on a circuit-switched network.

There is no need for additional physical hardware or wiring at the office. Scaling up is typically managed through a software-based administrative portal, where new users can be added by simply registering and configuring an endpoint.\u00a0<\/p><p>PSTN scaling, however, can be lengthy and time-consuming. Adding more users means ordering more physical copper lines from the provider, waiting for installation, and buying new hardware.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-0f1447e elementor-section-boxed elementor-section-height-default elementor-section-height-default wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no\" data-id=\"0f1447e\" data-element_type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-d49d53b\" data-id=\"d49d53b\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-0bf7462 elementor-widget elementor-widget-heading\" data-id=\"0bf7462\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"7_security\"><\/span>7.

A power outage or unstable internet could immediately disable the system, as most of the VoIP hardware relies on electricity to operate and uses the internet to transmit data. This is different from PSTN, which powers itself directly from the central exchange. This allows a traditional PSTN system to continue working during a power outage.<\/p><p>However, businesses can easily implement solutions to effectively counter this disadvantage. They can deploy solutions that reroute calls to mobile devices or a secondary internet connection.
