How SIP telephony works

1.Device registration

SIP clients (phones, computers with softphones) register with a SIP server (most often the SIP server of your VoIP service provider) by telling it their current IP addresses.

3. Establishing a connection

The SIP server processes the request and determines a route for the call, which may include forwarding through other SIP servers or connecting to the traditional telephone network via a SIP trunk.

2. Call

The user makes a call by entering a phone number or selecting a contact in their device.

4. Conversation

Once a connection is established, direct media (voice) exchange between devices over the Internet begins.
