It is not clear whether this is legal or not, but there is reason to believe that usage of the MS G.723.1 codec by programs other than those authorised by Microsoft is in violation of the DMCA. We choose not to use this codec for that reason - you make your own choice.

For PC to phone operation - you need a PC with Softphone software (we recommend X-Ten software) plus microphone and speakers (or a headset). Alternatively use dedicated Softphone hardware with an USB connector. For phone to phone operation - you need a VoIP device, either a VoIP telephone or a suitable VoIP adaptor (we recommend GrandStream ATAs). Broadband connection to the Internet, using a router with Ethernet connectivity for the VoIP telephone or adapter (if used).

The word "codec" comes from COder/DECoder. A codec defines the algorithm used to convert analog signal into digital signal and vice versa. Each algorithm consumes different amount of bandwidth and provides different voice quality level. In the VoIP world the codecs are used to encode the voice for transmission across an IP backbone. Another name for voip codecs is "vocoders".

POTS Codecs are most commonly used for live broadcast of news, interviews, traveling talk shows, sports, and entertainment audio. POTS Codecs often stand by as backups when ISDN or satellite is used for a primary feed. Some radio stations use a POTS Codec as a backup to their studio-to-transmitter link.

ISDN Codecs are most commonly used for remote broadcasts of traveling talk shows, traffic and weather services, and sportscasts. Today, many on-air personalities have ISDN connections at their home in order to broadcast from a home studio. Some radio stations use an ISDN Codec as a backup to their studio-to-transmitter link.

By default, PCMU(G711u) will be used. Both PCMU and PCMA will give you toll quality but their bandwidth consumption is also the highest (64kbps). If your network bandwidth is low, you can choose other lower-bit-rate codec such as G723 or G729 which will give you near toll quality at much smaller bandwidth consumption (G723 consumes 5.3/6.3kbps and G729 consumes 8kbps).

All you need is a broadband internet connection (DSL or Cable) and the appropriate hardware as determined by the VoIP provider you choose, usually a phone adapter box provided by them and a standard network router supplied by you (contact your provider for assistance in selecting a compatible router, and visit our router page to buy one at a great online price).

Chances are you cannot use VOIP with an existing "older" model cell phone. However, newer models with WiFi - a feature that can allows you to access local wireless area networks - can make and receive VOIP calls. When you make a call with a WiFi enabled cell phone, your voice travels wirelessly (over RF) to a WiFi radio receiver which is in turn connected into the Internet.

If you can have access to an ethernet connection or wireless access point, then providing there are no firewall issues, you can use your VoIP phone as though you are at your desk.

David, here’s what I think to do: Subscribe to Steve J’s .Mac service for my mac-equipped family that live on 3 different continents. With that, we can have email, iChat, calender & contact syncing, auto online mac backup w 2GB storage, auto drag-n-drop file upload/download & sharing (all formats), web site creation & publishing with group features, photocasting etc, etc. That would set me back $180 per year.

There are several companies that sell implementations of these codecs for various platforms. Be prepared to pay more than $10k for each codec implementation, plus $10 per copy sold/used.

If you have a special VoIP phone or a regular telephone connected to a VoIP adapter, the phone will ring like a traditional telephone. If your VoIP service requires you to make calls using your computer, the software supplied by your service provider will alert you when you have an incoming call.

ScenalyzerLive doesn't need to use a codec for capturing or playback. It uses the MS-DV codec for displaying pictures in the program. Your editing-application will normally use the MS-DV codec for type1 files and the currently installed vfw DV codec for type2 files. If for example the mainconcept codec is installed on your system, then type2 DV files are "mainconcept codec files".

A codec is a downloadable software encoder or decoder for a particular media format that is geared towards a specific computer platform.

Connection must be either 56kbs modem, or broadband ADSL or cable (connection via satellite is NOT recommended) We cannot guarantee compatibility with some WinME/9x video and possibly other drivers that tend to use 100% of processor for their needs for relatively long periods of time. This can cause the audio quality to degrade significantly and some things may not display properly. Click ere to view the User Guide
