The installation will bring with it a keypad that you can use to dial numbers. That is where the name “soft” derived from. Rather, it is software installed in a PC or computer. Softphones technically do not fall under the definition of a typical phone. Furthermore, it is a rather cost-saving method given the fact you need minimum resources. This information may sound complicated but once you have the right equipment, turning your existing phone to a special VoIP device is very facile. The circuitry generates the standard line voltage and ringing voltage that your phone is compatible with. What the ATA box so importantly does is turning analog information to digital. It can be used via the internet or any private data network. This maintains things like dialing and knowing when the phone is not in use. This is made possible by the help of CODECS or Coder/ Decoder.įurthermore, it uses SIP or Session Initiation Protocol. ATA stands for Analog Telephone Adapter, which channels the analog voice data into little packets of information.

To make your existing phone work with a VoIP technology, you will need an ATA box. By trying to force them to work, you will damage both the devices. That would not be possible as the connectors on the two devices are not of the same size or shape. However, you cannot just take your existing phone and plug it to your router or broadband modem. This means wires are involved here whereas with VoIP phones you can go wireless. On the other hand, traditional PSTN makes use of copper wires to transmit data and information. VoIP phones transmit information by the use of the internet. Their usage is slightly different from VoIP phones. For most of you, it will come as good news that you can use VoIP technology in your existing phones. When I searched for the power specs of this specific phone model (Siemens Openstage 15) I found these specs. The phone works only when connected to the cable coming from the POE switch.

I discovered that the phone is powered through Power Over Ethernet and when connected to the normal non-PoE dlink switch it doesn't work even though the main cable entering to the DLink switch is coming from a POE switch. The problem arose when I connected the VoIP phone to the dlink switch, it didn't boot up. So, I bought d-link switches (des 1008a) for each office and decided to expand the network inside each office by connecting one of the already existing sockets to the dlink switch and then connect the PCs and phones to the new switch. I found that there's already two Ethernet sockets in each office but they are connected to VoIP phones (Siemens openstage 15). I need about 8 Ethernet sockets in each office of the site.

I'm working on a project where I need to make a network for all PCs in the site.
