Call Using SIP

What Is SIP

SIP is a modern protocol for voice and video communication over the internet. It’s extremely cheap and easy to install and manage.

SIP is an open-source protocol and is widely used by numerous developers and manufacturers of PC-based softphones (many are free), hardware SIP-enabled phone sets, SIP gateways for connecting SIP with conventional phone networks and SIP-enabled PBX systems for use in offices.

The best thing about SIP is that using it is entirely free. It can be used to make calls to destinations worldwide.

How Does It Work?

VoIP is a common term that used for transferring voice over the internet. SIP is an open-source protocol that uses VoIP to allow you to make calls using the internet. All you need is either a hardphone (phone boxes that are connected to the internet) or a softphone (applications on a computer that would allow you to communicate over the internet).

To know if a particular hard phone or softphone can be used for this service, look for, “supports SIP” under specifications. An example of a soft phone that is easily available is the X-Lite dialer ® Counterpath Technologies. There are several other similar programs which are also available online.
