VoIP enables you to use your existing broadband capacity to carry regular voice calls to suitably equipped remote sites, for example another Vigor2600V router. The Vigor2600V also has enhanced VPN capacity and Internet content filtering. Versions are also available with an ISDN interface and a built-in wireless access point.

The calls between the two sites in the example above are free of charge because they are making use of your existing always-on ADSL connection, but cost isn't the only advantage; using VOIP means that you have additional call capacity in your home or office, without tying up your regular phone line.

The voice calls (speech) are compressed in real time to make maximum use of the bandwidth, similar to the way that an MP3 audio file contains compressed sound and other internet activities (e.g. web browsing) run simultaneously with the VOIP calls. A preset QoS system automatically gives voice traffic priority.
