Why need IP telephony ?

IP Telephony is transforming communication by leveraging internet protocols for cost-effective voice and video services. Unlike traditional phone services burdened with taxes and regulatory fees, basic IP plans start around $10-$15, offering substantial savings. With shared infrastructure, it supports multiple service providers without geographical restrictions. Modern IP phones, including hard and soft variants, deliver advanced features like conferencing, web browsing, and integration with cloud services. This versatile technology suits businesses of all sizes, enabling features like free calls, call center operations, and user profiling.
