There are literally hundreds of providers today offering Internet-based digital telephony solutions, often referred to as Voice over IP or VoIP. These companies include MagicJack, Skype, Vonage, and Vitelity just to name a few.

The Anvil communications network generally provides an excellent backbone for VoIP. Customers are generally very satisfied with digital voice quality. It is important to understand, however, by virtue of the fact that  a native analog voice signal is being digitized, packetized, and transmitted over a sometimes crowded network, voice quality can be compromised. This manifests itself with occational voice "warbling." On the other hand, VoIP service often offers the opportunity for significant cost savings over traditional telephone service.
