SIP phones are used in a VoIP telephone system. There are more versions and
types of them:
SIP SoftPhone-Software-based SIP Phone
A Software-based SIP phone is an application that uses the microphone and speakers
of your computer, or a connected headset in order to make it possible to make and receive calls.
Hardware SIP phone
A Hardware-based SIP phone looks and works like a normal phone. However, it is
connected directly to the data network instead of standard PSTN lines.
These phones have an integrated mini hub, so they can share the network connection
with the computer. It means that there is no need for an additional network point to the phone.
Use of analog phone through ATA adapter
Your current phone can also be used in the VoIP phone system with the help of an
ATA adapter. An ATA adapter makes it possible to connect the Ethernet network jack
and the telephone to the adapter. So, the old phone will appear in the VoIP phone system
as a regular SIP phone.
Purchasing VoIP phones is not costly, and it can easily be procured in an online shop
of VoIP products.
