What is a SIP number and what is it for?

Using a SIP number opens up a wide range of business opportunities. It allows you to organize virtual telephone systems and call centers with access to the public telephone network, as well as integrate with online telephony and instant messengers. In addition, SIP numbers can be used as a private person to securely communicate with your relatives or friends via the Internet.
In summary, SIP numbers are a convenient way to communicate over the Internet using the SIP protocol. They are flexible, cost-effective and have many features. So, if you are looking for a way to make and receive calls over the Internet, you should definitely pay attention to SIP numbers and their advantages.

How does SIP telephony work?

SIP telephony is a modern way to make phone calls using the Internet. Let’s look at how this happens and how SIP telephony works.

• Registration: When you connect to the SIP telephony service, you get your SIP number and set up the application (on your phone or on your PC). This allows you to identify yourself on the network and use SIP telephony.
• Establishing a connection: When you want to make a call, your SIP client (application or device) sends a connection request through the SIP server. The SIP server verifies your identity and tries to find the recipient of the call.
• Signal transmission: After a successful connection, your voice signal is digitized and transmitted over the Internet. Voice data is broken into packets and sent through the network to the recipient of the call.
• Receiving a call: When a call reaches the destination, its SIP client receives the signal, decompresses the packets, and restores the voice information. Thus, the call becomes audible to the recipient.
• Ending a call: When the call ends, one of the parties ends the connection, and SIP telephony frees up resources for other calls.

Thus, SIP-telephony allows using the Internet to transmit voice data and provides communication between subscribers. It offers the flexibility and affordability to use SIP telephony anywhere you have an Internet connection.
