Long before the widespread introduction of Voice Over Internet Protocol (VoIP) calling to the masses, this type of internet-based network calling was in use by phone provider for long-distance services. And more often than not, landline and even some cellular providers are tapping into VoIP calling for long-distance calls. Why? VoIP relies on internet networks, or IP connections. By using these gateways, companies such as Net-Tell LLC that provide VoIP calling rely on already-available, streamlined, low-bandwidth waves for connecting calls. Many other landline and cellular providers tap into the knowledge widely provided by Net-Tell and others for long-distance due to its availability, feasibility and ability to reduce bandwidth in comparison to their typical phone call offerings.
