More and more companies are switching to online calling. That's obvious, because it is flexible, scalable, and often cheaper than traditional lines. But in that process, a technical term comes up: SIP.
What is the SIP protocol? How does it work? And what should you do with it? In this article, we answer the most frequently asked questions about SIP Session Initiation Protocol, SIP servers and other components of calling over the SIP Internet Protocol.
What is the SIP-protocol?
SIP stands for Session Initiation Protocol. It is an Internet protocol that sets up, manages and terminates calls. Simply put: without SIP, two devices cannot connect to start a call. Whether you are calling from a Gigaset device, Yealink or Snom - the SIP protocol handles the connection.
What is a SIP-server?
A SIP server is the central place that coordinates SIP traffic. It ensures that your phone knows where the call should go, who is being called, and how the call will be handled. You can think of it as the router of your phone calls.
What is the difference between VoIP en SIP?
VoIP is calling over the Internet. SIP is the protocol that controls how those calls are made. So you need VoIP to make calls over the Internet and the SIP protocol to set up and manage the call.
