KSU Configuration for Session Initiation Protocol (SIP) Trunks.
** N = Network ID H = Host ID Private IP Addresses:
Class A 10.0.0.0 - 10.255.255.255
Class B 172.16.0.0 – 172.31.255.255
Class C 192.168.0.0 –192.168.255.255
* 127.0.0.0 is reserved for loopback diagnostic functions
0.0.0.0 is a “special case” available for use as a broadcast address.
Static IP Addresses are manually assigned and do not change.
Dynamic IP Addresses are assigned via DHCP and may change from day to day.

The Session Initiation Protocol (SIP) is a signaling protocol used for establishing sessions in an IP network. A session could be a simple two-way telephone call or it could be a collaborative multi-media conference session.SIP is developed purely as a mechanism to establish sessions, it does not know about the details of a session, it just initiates, terminates and modifies sessions.
Over the last couple of years, the Voice over IP community has adopted SIP as its protocol of choice for signaling. SIP is an RFC standard (RFC 3261) from the Internet Engineering Task Force (IETF), the body responsible for administering and developing the mechanisms that comprise the Internet. SIP is still evolving and being extended as technology matures and SIP products are socialized in the marketplace.
SIP Is A Text-based Protocol. The Client Makes Requests and the Server Returns
Answers to Client Requests Using Two Types of Messages. Requests (Methods)
And Answers (State Codes).
*A Server sends a 1xx response if it expects to take more than 200 ms to obtain a final response
The Initial Line/Request Line Is Most Important Part of SIP Request. It Contains
the Method Name, Request URI and SIP Protocol Version. There are Six Basic
Methods (RFC 254) for Client Requests
