Notes:
* Shading denotes most popular broadband services in the current market
* Bandwidth requirement for best voice quality is 17Kbps per IP call using 1 frame/packet. It is possible to make calls with less than 17Kpbs bandwidth, but call quality issues may result.
* Dial-up internet connections are not recommended to avoid possible call quality issues due to network congestion.
* The bandwidth is conserved less if silence compression is used when there is no voice traffic during the call.
