Abstract
Devices and systems for voice over Internet protocol (VoIP) codec selection are described herein. One or more embodiments include a VoIP device for selecting a codec comprising a link monitor to detect an Internet link and an interface coupled to the link monitor, wherein the interface determines a bandwidth, usage, and/or type of the Internet link to select the codec.
Claims20
A voice over Internet protocol (VoIP) device for selecting a codec, comprising:
- a link monitor to detect an Internet link by at least one of monitoring electrical characteristics, link status, or checking networking reachability of the Internet link;
- and
- an interface coupled to the link monitor, wherein the interface determines a bandwidth, type of the Internet link, and usage to select the codec, and wherein the usage includes at least one of voice data or video data.
An edge device, acting as a back-to-back user agent for a VoIP device upstream, for selecting a codec during a call, comprising:
- a link monitor to detect a switch from a first Internet link to a second Internet link;
- and
- an interface coupled to the first Internet link and the second Internet link, wherein the interface determines a bandwidth, type of the second Internet link, and usage to select the codec, wherein the usage includes at least one of voice data or video data, and wherein the bandwidth is calculated by a bandwidth detector using a packet timing operation.
A system for selecting a codec for a call, comprising:
- a link monitor to detect a first Internet link by monitoring at least one of electrical characteristics, link status, or checking networking reachability of the first Internet link, wherein the first Internet link has a first bandwidth range, is a particular type of Internet link, and has a particular usage;
- and
- an interface coupled to the first Internet link, wherein the interface selects a first codec to couple the first Internet link to based on the first bandwidth range, the particular type of Internet link, and the particular usage, wherein the particular usage includes at least one of voice data or video data, and wherein the first codec bandwidth range overlaps with at least a portion of the first bandwidth range.
