With a conventional telephone system, analog or digital telephones are plugged into an extension socket connected to a PBX or Key System.
With IP Telephony, the telephone is connected to the IP PBX via the LAN. There are two basic types of IP phones:
A software application (iPhoneManager Pro) that runs on the user's PC, allowing them to use either a headset or a microphone, and their PC Keyboard to access telephony features.
One number service" offers the possibility to make any standard mobile phone part of the company system.
* VoIP: Voice over Internet Protocol, a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions of the PSTN (Public Switched Telephone Network). One advantage of VoIP is that the telephone calls over the Internet do not incur a surcharge beyond what the user is paying for Internet access, much in the same way that the user doesn't pay for sending individual e-mails over the Internet.
