How SIP Powers a VoIP Session Call Flow
Registration
When a user agent launches, it has to register with a VoIP SIP server so it can be found by other users. This happens by using the SIP Register request message.
Establishing a call
SIP invite request:
The SIP invite initiates an attempt to establish a call. This is sent from the caller to
the SIP server where it finds the call receiver’s number. Once the number is located,
the invite is forwarded.
SIP response 100:
A message is sent from the SIP server to the end user’s number in order to confirm the
invite request.
SIP Response 180:
This message is a confirmation that the invite has been received and the user agent is
alerting the user.
SIP Response 200:
A 200 response is sent to confirm a call when it is answered by the end-user. This
message results in an exchange and negotiation of VoIP call parameters. SIP Ack Request:
The caller confirms the call by sending an Ack request to the number called.
Managing a call
The VoIP call is transmitted between the user agents using RTP (real-time transport protocol), which is also used for sending audio and video data over IP networks.
Terminating a call
When a user ends a call, a SIP softphone client Bye request is sent. The call can be ended from either side of the line. The termination is confirmed by the other user agent with a SIP 200 status code response.
