Among modern communication methods, calls from SIP numbers are becoming increasingly popular. If you are interested in simplifying and improving your communication experience through telephone communication, then you will find this article useful.
When and how SIP numbers appeared
SIP numbers emerged in the context of the development of Voice over Internet Protocol (VoIP) technology, which allows voice and other multimedia data to be transmitted over the Internet. The term SIP (Session Initiation Protocol) itself stands for Session Initiation Protocol and is used to establish, manage and terminate multimedia sessions such as telephone calls over an IP network.
The history of the emergence of SIP numbers is linked to the development of digital telephone systems and the transformation of traditional telephone networks towards IP technologies. Here are the key stages of their development:
What SIP numbers are and what role they play in the SIP protocol
A SIP number is an identifier that is used to make and receive audio and video calls over the Internet using the reliable Session Initiation Protocol (SIP). Unlike a regular phone number, this one is created in a virtual format and is not tied to a specific location or physical device.
To use a SIP number, you need a device with an Internet connection — IP phone, analogue phone with VoIP gateway or any other device that can download the appropriate softphone software (Zoiper, PortSIP, etc.).
Virtual numbers perform several key functions in the SIP protocol:
Basic principles of SIP-numbers operation
The process of making calls to landline numbers, mobile numbers or other SIP numbers using SIP technology is generally as follows:
Step 1: Registration on the SIP server
A SIP client is configured on the user's device and a connection is established between the client and the SIP server using identification data (SIP address, SIP login and SIP password). The client sends a registration request and if all the details are correct, the connection is established.
Step 2: Initiating a call
The user selects the number he wants to call (landline, mobile or SIP number). After that, the SIP client forms a SIP request to initiate the call, which is sent to the SIP-server.
Step 3: Establishing a connection
The SIP server processing the request checks the correctness of addressing and searches for the subscriber in the network. If the subscriber is found and available for communication, an audio session is established between both clients.
Step 4: Ending the call
After the call is completed, the user closes the connection. And the SIP server releases the resources intended for the session and prepares for the next request.
How a SIP number differs from a mobile and landline number
SIP numbers, mobile and landline are widely used for communication in the modern world. To understand which one is better to choose, you need to understand the differences between these types of numbers:
VoIP (Voice over Internet Protocol) technology is used to make calls from SIP numbers. Fixed numbers are based on PSTN technology (Public Switched Telephone Network), while mobile numbers use GSM technology (Global System for Mobile Communications).
SIP-number is not tied to geographical location, which is very convenient. Whereas the use of a landline number is geographically limited, and the condition for using a mobile number is the availability of GSM connection.
Devices for making calls from SIP numbers don’t require laying a telephone line: an Internet connection and a VoIP device are sufficient. To use landline numbers, you need a phone line and a landline. And to use a mobile number you need a mobile device and a sim-card.
Connection of a SIP number doesn’t require laying additional communication lines, and the number itself is easily scalable depending on user needs. Fixed-line communication is characterised by limited scalability and requires additional communication lines in order to increase the number of numbers. Mobile communication can be scaled up only by adding new mobile numbers (by purchasing sim-cards).
A SIP number offers a wide choice of additional functions (call forwarding, voicemail, IVR-menu, etc.). Whereas the choice of functions of a landline number is limited to the basic ones, and a mobile number — only a few additional ones (call forwarding and voicemail).
Different operators offer packages of services with different content. The choice should be made based on the tasks that the number should fulfil. Fixed-line calls are the most expensive. And the cost of mobile and SIP-telephony depends on such factors as the direction of calls, functionality, etc.
SIP numbers with their high level of customisation flexibility win out over both fixed line numbers with their limited customisation functionality and mobile numbers, whose level of flexibility is characterised as medium.
Unlike a landline number, which supports only voice calls, SIP and mobile numbers support both voice and video calls.
When choosing between a SIP, mobile and landline number, consider your own needs. But if mobility and affordability are important to you, SIP number is the best option among them.
Applications of SIP numbers
SIP numbers can be conveniently used in business to organise workflow in various formats:
SIP numbers can also be used for personal purposes to securely communicate with your family or friends using an Internet connection. After all, it is essentially an ordinary landline number, which can be easily connected to the Internet and thanks to this expands the possibilities of users.
What are the advantages of using SIP numbers
Compared to using conventional numbers, SIP telephony provides users with a number of advantages:
