IP world v/s Green?

Posted by tggokul on February 4, 2009

With the whole world talking about greener devices/Applications, I am kind of wondering whether people who evangalized “IP” as a platform for communication kept this in mind. Let me tell you why this thought.

I don’t see one single Message Packet either in SIP/H323/MGCP that will enable the server to switch off the endpoints when they are not active. Isn’t that weird? Now lets say that as a monitoring application, I find out that an IP Phone ( could be using any of the above signalling protocols) has not been used (maybe in a conference room) for “x” days, shouldn’t I have the option to switch it off remotely? Shouldn’t there be a protocol that supports this action?

At a much larger level, is there a “Green” protocol at all? Maybe a protocol that will exchange power consumption data between the server/endpoint that will enable an administrator to make informed decisions.

I am seeing something equivalent to a GMS ( Green Monitoring System) similar to an NMS (Network Monitoring System) that would exchange power related data and the adminstrator could take decisions based on that. The devices under control could be anything from a tubelight to a washing machine. It is just not communication devices that are becoming smarter. Consumer electonics are equally there as well.

The need of the hour is to create one such protocol. Not sure whether anybody is working on that.

    Perhaps I could interest you in http://whitepapers.silicon.com/0,39024759,60317829p,00.htm ?

    There is a relatively new standard for consumer electronic devices called DLNA. (There are already some devices which DLNA support primarily in the East.)

    Nice idea….

    Actually, i’m trying to one thing. Hope you can help me.

    I’m having two IVRs (Numbers are 123 and 321 ….. I have a softphone (XLite).

    I will explain in steps…

    1) IVR 123 will play something and will expect some input

    2) IVR 321 will just play whatever IVR 123 is expecting.
    Eg. if IVR 123 says, “Press 1 for English. 2 for Spanish”, IVR 321 has to Send the DTMF tone for 1. I download the tones from voxeo. I played the tone from the IVR 321 to IVR 123, but its not able to detect that….. Any idea why?

      Hi Ananth,

      I don’t understand the flow yet. Is the “321” IVR calling the “123” IVR. If that is the case what are doing with xlite? What IVRs are these? IP or TDM IVRs?
