What is ip switchboard and analog switchboard? The features and benefits that IP PBX brings are different from analog PBX. This is a problem that most companies wonder about whether to choose an IP switchboard or an analog switchboard. Companies, offices, collectives, hotels, restaurants, motels, factories, private houses…. need to communicate internally, divert calls to people who need to listen and secure the phone call (not installed in parallel).
An IP PBX is a voice system operating on an IP basis. With IP PBX, in addition to making internal calls, calling to PSTNs, mobile networks, the system can also transmit voice and video over LAN, WAN and Internet.
IP-SIP telephony (VoIP) technology is attracting investment interest due to free calling rates through prepaid lines (see article on pre-dial VoIP)
* Analog switchboard:
The current Analog PBX system (most businesses that use it) can also be upgraded to use SIP-IP (H.232) by adding auxiliary equipment.
The analog signal is a continuous signal, the graph represents the analog signal as a continuous line (e.g. sine, cos, or any up and down curve), analog means analog, analog means analog Later signal also has the same form as before, saying same does not mean the same but similar in nature, but will differ in signal strength later than before. Power analog signal is electric current, in life analog can be the sound signal we hear, images we see, in telecommunications is electromagnetic wave (ie invisible light).
