Requirements for SIP-Based Communication
If an individual wants to communicate using the SIP technology, he/she is required to have the following:
1) A SIP Account/Address
A SIP account is something similar to a phone number that we have in the traditional landline system. It is unique for each individual across the globe. There are many different SIP service providers offering SIP accounts. A SIP address resembles the email address and has a user name and a domain. When you register for a SIP account with a service provider, you receive a SIP address. This SIP address is the SIP version of a phone number that people use to call each other.

3) An active Internet Connection
An internet connection with sufficient bandwidth is a must for making and receiving SIP calls. While SIP voice calls can work on low bandwidth as well, SIP video calls require high bandwidth.

In order to listen to what is being said and to communicate your voice to the other person, hearing and talking devices like microphone, headset and earpieces are required. In addition to these, video calling requires a webcam too.
5) Friends to Talk To
For making calls to your buddies, pals or associates, they need to have a SIP account and SIP address similar to what you have. SIP calling just requires a SIP address and you are ready to go. On the other hand, one can also talk with people that use traditional lines instead of SIP lines using a smart VoIP solution working on top of the SIP model.
Functioning of SIP
Once a user gets a SIP address and the SIP client is successfully installed on the computer or mobile phone, the configuration of the SIP client is needed. This is not much of a problem in modern times as it is taken care of by the configuration wizards which are available. However, you need to key in your SIP credentials and fill in the required fields in the SIP client and you are ready to launch in a few minutes. When a user uses a specific SIP solution such as a mobile SIP dialer, the configurations are provided by the service provider.
Considering the benefits that SIP has, it is evident that any VoIP solution developed by using the true potential of SIP is a very well established communication solution because of its reliability, huge potential, cost savings, and user friendly interface.
