[cisco-voip] Streaming multicast audio source to an IP phone

[Tim Reimers]

Hi everyone-

 

I'm researching how to possibly do something with IP phones and
multicast-

 

We want to stream audio from meetings in a very plug-and-play
user-friendly way,

to IP phones and also PCs on the network.

 

I will be locating some type of hardware that can be connected to the
line out of an audio system to pick up the audio, and provide a 

multicast stream. 

The multicast stream will NOT be coming from an IP phone - 

It will be something like a PC with VLC loaded on it, or with proof of
concept to get some funding, I might use a VBrick or something like
that.

 

We want it to be a black box that a non-technical user can just switch
on along with the audio system for the meeting room, and streaming 

will automatically begin.

 

On the receive side, we want users to be able to listen to the stream on
an IP phone or a PC, without having to

do much more than select a service or dial a number on the system, or
click a link with a PC.

 

This is a one-way listen to the meeting; there is no need or requirement
for audio from the client side, so the IP Phone should automatically go
into speakerphone mode with mute, or allow audio to handset/headset

 

I have seen the below from the IP Phone SDK - I don't know if I could
leverage that into a service that is 

pre-programmed to join a multicast "conference" (aka audio stream, for
my purposes) 

on a known multicast IP.

 

Thanks for any advice you guys have! 

 

I know sometimes I forget to come back in here and thank you for times
you give me great assistance-

Along those lines, major thanks to Peter Snow and others who assisted me
with

echo cancelling questions and PRI setup! 

 

14. MConference (JSP)

 

MConference is a sample application which allows users to create, join,
and control IP multicast conferences
from an XML phone service. It's a good example of the power of XML
services and IP multicast - providing a large-scale (thousands of
participants), arbitrated conference using a simple web application.
Conference arbitration can be enabled/disabled by the conference owner.
When arbitration is enabled participants must request permission which
is then granted by the conference owner. When conference arbitration is
disabled, participants can simply push-to-talk, similar to a
hoot-and-holler network.
