What Is a SIP Account and How SIP Connection Works

SIP account is a key that is used to activate your Voice-over-IP (VoIP) communication hardware and software enabling you to make and receive calls over the Internet.

About SIP Technology

SIP (Session Initiation Protocol) system usually works as an element within VoIP software which allows users make and receive calls (including long-distance and international ones) via wireless networks to mobile phones, landlines and other PCs. Other than that, SIP phone numbers can be used simultaneously with other phone numbers, allowing callers to stay in touch wherever they are.

How SIP Accounts Work and What Is IP Telephony

SIP is a protocol for Internet telephony that 'activates' your VoIP devices and makes it possible to receive and make calls, hold audio and video conferences and chat online. The main difference between conventional and IP telephonies is in that the latter does not use traditional wire circuit to convey the voice. The vocal data is now transmitted in the form of IP packets with the help of software or hardware and software combination. The data are converted into a digital format and compressed by the sender and is decompressed and reconstructed by the opposite side. In simple terms, IP telephony has made a significant qualitative leap in switching from traditional expensive hardware to cost-efficient, easy in maintenance software.

How to Select a VoIP Provider and Obtain a Free SIP Account

Having a SIP account enables you to receive and make calls worldwide for a reasonable price or at no charge at all. So, here is how you can obtain such account:

Choose a service. There exist plenty of companies offering both paid and free SIP accounts. If you are a beginner, you may try with a free, basic account to investigate its features and see whether it is just what you need. Or you can subscribe for a premium membership to get the additional features and by-services.

Go to the registration page. Once you have found the company offering the SIP service, go to its official website and register your account there. As a rule, there is nothing daunting about creating SIP accounts, you will just need to fill in the standard form (it resembles the ones for email registration).

Decide on username and password. To complete the registration process you will need to think up a unique username. The username you select will be then a part of the SIP address which in fact resembles the email address (it contains the '@' symbol). Select a good, reliable password and submit the entered data.

Check your email. As a rule, SIP service providers send the full credentials you need to enter and configure your account to your email provided in the registration form. This particular email is very important. In case you don't see it in your Inbox, check your Spam folder. The confirmation email usually includes essential information on how to access your new account and adjust its settings for your convenience.


When registering, it is essential to provide a valid data (namely, the email) in order to get the credentials, configure and start using your SIP account.
