In terminology that are easy , it is the infrastructure that permits for public and private telecommunication. It interconnects telephone lines, cellular networks, fiber optic cables, and undersea telephone cables, which enable devices to come in contact with one another.

SIP Trunking

Communications providers use SIP Trunking to connect PBX combined with the standard telephone network to send and receive calls with the web. It is the simplest way to retrofit a current office PBX with VoIP connectivity.

Codec

When speaking about codec in the context of VoIP, the task of theirs is actually compressing VoIP data to save bandwidth as well as improve connection speed.

Codecs offer much more than bandwidth optimization, they can make the calls of yours sound outstanding with two times the frequency range of a regular telephone call by utilizing the G.729 or G.722 codecs. There are many other codecs as well like G711alaw, G711ulaw etc. 

Powerful Host Configuration Protocol (DHCP)

DHCP is actually utilized by client side network devices to be assigned an IP address along with other necessary parameters to create a connection. What's more, it ensures IP addresses are different. VoIP phones could be configured with a fixed or perhaps a powerful IP.

Jitter

Jitter is definitely the variation between the time needed for a package of data to attain the spot. If the jitter is actually high, users perceive this as "lag."

Latency

Latency is actually the interval between a signal being sent and this arriving at the various other endpoint. Put simply, it is the period of time it takes for a user's voice to be read by the recipient.

Class four softswitches help connecting and route calls throughout long distances (and also in huge volumes) while class five softswitches are devoted to smaller, local places. 

Essentially, class four softswitches route traffic between the different class five softswitch
