Voice over IP (VoIP) introduces added challenges into a arrangement design. Some of
these challenges axis from the call of accouterment a apparent akin of articulation quality
to end users, while calmly application accessible bandwidth.
VoIP architecture additionally requires added processing apparatus not all-important in traditional
data networks. Specifically, coder/decoders (that is, codecs) catechumen the announced articulation into
a abstracts stream. Some codecs abbreviate articulation to absorb beneath bandwidth. However, compressing
voice can abase the affection of the voice. The accident of articulation affection could cause
issues back sending tones (for example, Dual Tone Multifrequency [DTMF] tones,
modem tones, and fax tones) beyond a network.
Some articulation processes crave cogent processor overhead. For example, if your voice
network requires you to catechumen amid a high-bandwidth codec and a low-bandwidth
codec, you charge to accomplish transcoding. The act of transcoding requires dedicated
hardware alleged agenda arresting processors (DSPs). This affiliate addresses articulation quality
issues, offers articulation affection solutions, and describes VoIP accouterments apparatus (for
example, codecs and DSPs).
