Ajax Push and the Telephone


The telephone is an excellent source of asynchronous events — you never know when it is going to ring. This means that web-based views of the telephony space make for interesting applications of Ajax Push.

Using SailFin and ICEfaces we've put together a very simple call setup demo. It shows when your phone is online and allows you to initiate a call between any two phones just by selecting them and pressing "call".

To run the demo:

  1. Download a recent build of SailFin.
  2. Download the demo binary callsetup.sar.
  3. java -Xmx512m -jar sailfin-installer-v1-b36-darwin.jar
    cd sailfin
    ant -f setup.xml
    bin/asadmin start-domain domain1
    bin/asadmin start-database
    cp callsetup.sar domains/domain1/autodeploy/

  4. Point your SIP phone (such as X-Lite Demo) at a localhost Proxy.
  5. Point your browser at http://localhost:8080/CallSetup/registrations.iface

As phones connect and disconnect, the list in the registrations page will be dynamically updated, showing user presence.
