Session Initiation Protocol iv 10. SIP The following image shows the basic call flow of a SIP session. Given below is a step-by-step explanation of the above call flow: 1. An INVITE request that is sent to a proxy server is responsible for initiating a session. 2. The proxy server sendsa100 Trying response immediately to the caller (Alice) to stop the re-transmissions of the INVITE request
This call flow shows the SIP call setup between a SIP client (192.168.0.10) and a SIP server (216.234.64.8). The flow also shows the RTP message flow between the SIP client and the Media Gateway (216.234.64.16).
The above explanation and call-flow successfully actualizes the envisioned usage of SIP as a messaging protocol between two MGCs. Consider the Add Termination message (M20).

VoLTE call flow and procedures is very big area to cover because of the many scenarios to consider from both UE and network perspective. In this article I will try to put some examples of VoLTE call flow from UE point of view.
Before we describe the flow of a typical SIP call, let’s have a look at how SIP user agents register with a SIP registrar. The example below shows a situation where an SIP softphone (namely, the Ekiga client) registers with an Asterisk PBX. The Asterisk’s IP address is 10.10.1.99, while the client is at 10.10.1.13 and wants to register the telephone number 13.
I’d like to insist here that SIP is a signalling protocol, its NOT a media protocol — which means it is a set of rules use to control the signaling part of a media session. It doesn’t have any control on media. So let’s not wait to start the basic call flow of SIP.

The Session Initiation Protocol (SIP) [4] was the attempt of the IETF community to provide a signaling protocol that will not only enable phone calls but can be also used for initiating any kind of communication sessions.
Call Flow Between Two SIP Gateways Cisco routers, including CME routers, can act as SIP gateways for calls that originate from non-SIP phones. The gateways function as SIP UAs and set up a SIP session between them for each call.

The IETF “Session Initiation Protocol Call Control – Transfer” describes methods by which SIP UAs can provide call transfer services using such SIP extensions as REFER (RFC 3515), Replaces (RFC 3891), Referred-By (RFC 3892),and sipfrag (RFC 3420). Some examples of these services include blind transfer and attended transfer.
