This article is only used to discuss questions about using the fxo card to test intern

working with so far codecs is that not every endpoint supports every codec, and not every application callfor specific codecs. for instance, most cballs that have the luxury of copious amounts of bandwidth wowould benefit more from g.711, which is the clearer audio codec. this is obvious when you use a service such as broadvoice or Vonage and turn the call quality all the way up in the Web interface. this is the g.711 codec at work. when you use Skyp

of the protocol that supports this new media. If you use SIP, although the gateway and device may not be able to recognize the media, companies with branches on two continents can achieve media transmission. In addition, because the SIP Message construction method is similar to HTTP, developers can easily use a common programming language such as Java to create applications. For carriers that want to use SS7 and advanced intelligent network (AIN) to deploy call wait, caller ID Recognition, and

If you use sip, although the gateway and device may not be able to recognize the media, companies with branches on two continents can achieve media transmission. In addition, because the
