SIP COMMUNICATOR

• A software-based IP phone that runs on a PC
  audio/video.
• You can use SIP COMMUNICATOR to place VoIP phone
  calls between two PCs or between a PC and an IP
  Phone(such as the one in the E2-2363 Lab)
• A SIP User Agent in Java.
• Can act as a client creates a SIP request and
  sends it.
• Also as a server generates a response to a SIP
  request.
• Based on JAIN SIP libraries and JMF
• (More info on the architecture at Emil Ivovs
  project site http//www.emcho.com/)
• Project info and download at https//sip-communica
  tor.dev.java.net/
• ECE355 project will be based in the alpha version
  for Windows (sip-communicator-windows.zip).

JAIN-SIP-PRESENCE-PROXY

• SIP Proxy, SIP Registar, and SIP Presence server.
• SIP proxy servers help route requests to the
  user's current location, authenticate and
  authorize users for services, implement provider
  call-routing policies, and provide features to
  users.
• SIP Registar servers allows users to upload their
  current locations for use by proxy servers.
• Based on JAIN SIP libraries
• Project info and download at http//snad.ncsl.nist

Eclipse Projects SetupCVS Repositories in Group
Accounts

• You create your projects in Eclipse importing the
  source code from your group account in UNIX.
• There is a CVS repository in each group account
  called sip-communicator.cvs
• In this CVS Repository, there are projects that
  contain the base source code for the ECE355
  project
• Sip-Comunicator-Fall05
• sipproxy

9
Eclipse Projects Setup

• For each project SIP COMMUNICATOR and
  JAIN-SIP-PRESENCE-PROXY, you will need to
• Checkout code from group CVS repository
• Set up Run Configuration parameters in Eclipse
• May need to change configuration settings for the
  project in project .xml files.

10
Eclipse Projects Setup Checking Out Project from
CVS

• FileNewProject
• In Project Wizard select CVSCheckout Project
  from CVS
• Next, select option Create a new repository
  location
• Repository path is
• /home/e355gNN/sip-communicator.cvs
• NN Group Number
• User ID, and Password for UNIX Accounts.

Running AppsSIP COMMUNICATOR

• SIP COMMUNICATOR reads execution parameters from
  sip-communicator.xml file
• Parameters in this file are currently set so that
  SIP COMMUNICATOR will use the SIP Services
  provided by JAIN-SIP-PRESENCE-PROXY running
  locally (127.0.0.1).

• SIP PROXY uses reads parameters from
  configuration.xml file
• Parameters in this file are currently set so the
  SIP proxy runs in the same machine using Port
  4000.

Making a SIP Phone Call

• For testing, you can run the two instances of SIP
  Communicator in one machine. You will need to
  change the SIP port, Audio and Video ports in the
  sip-communicator.xml files for the second
  instance.
