Tutorials on SIP and SIP SER server

This and other SIP Workshops were the collective contributions from members of the APAN SIP/H323 Working Group under the steard of Stephen Kingham and Quincy Wu (aka AAron Solomon).

This was Version 2: 17 May 2004 and was probably the first full day SIP workshop run at an international network research conference. This workshop was conducted at the APAN/Questnet Jul 2004 Cairns conference.

The contents of an updated tutorial that was more like the ones run at the following locations can be found by clicking here:

Around Australia 2004/2005 for the Australian Universities and one for the Terrapin VoIP conference in Melbourne,

This page will provide information and details required by prospective participants for a hands-on SIP workshop/tutorial. Details will include:

Objectives
Preparation needed by Delegates and what is being supplied at the Tutorial
Course outline
Details of when and where the workshop will be held.
Technical description of VLANs, LAN and WAN provided at the Tutorial

Any questions or suggestions should be directed to Stephen.Kingham@aarnet.edu.au

OBJECTIVES:

Teach the SIP protocol.

To get participants to build their own SIP VoIP servers with GPL licensed software SER. For the participants to gain maximum benefit they should bring bring or have access to via the internet a Linux/FreeBSD PC for this hands-on workshop and install necessary software packages to support them making VoIP calls between participants in the workshop and externally. After the SIP peering for VoIP is established in this workshop, participants would take those servers home and the VoIP peering would continue to work and hopefully become part of the Internet2 SIP.edu initiative.

PREPARATION NEEDED BY DELEGATES

Delegates are encouraged to have their own Unix server built before the Tutorial/Workshop so that they can install and configure the SIP Proxy Server and keep it running after the Tutorial. There will be approximately 5 unix servers for delegates to use during the Tutorial for those who do not have their own.

Only very specific Unix Versions will be supported at the Tutorial. Details of what they are and configuration details are available here. If you have your own preferred Unix Version we cannot stop you using it but we will not be able to help you if there is a problem.

WHAT IS BEING SUPPLIED:

The Delegates will be split up into 10 groups, we will keep Delegates from the same institution together unless specifically requested not to.

There will be about 5 Unix Servers at the Tutorial for Groups that do not have one.

There will be a range of SIP Telephones available for Groups to use.

COURSE LOCATION AND TIME:

18th APAN Meetings/QUESTnet 2004 in Cairns Australia

Room B, Hilton Cairns Hotel

Saturday 3 July 2004

Technical description of VLANs, LAN and WAN provided at the Tutorial

Delegates will need to refer to the IP Address allocation and the LAN configuration provides each group between 5 and 6 ethernet ports.

Each "group" of delegates will get allocated a small subnet on their own VLAN. That way their SIP Server and IP Telephones will operate independantly from everyone else. This is particulalrly important to allow that groups IP Telephones find the right tftp server.

Each VLAN will have a DHCP server which will also provide the Gateway, DNS, and TFTP Boot Server IP address.

The TFTPBoot server will be one of the IP Addresses in each groups allocated IP Address space.

A Domain Name Server will be running at the Tutorial that all delegates should use this DNS Server. This is important so that "dumy" SRV records served from the DNS server are used by Delegates.
