Can anyone suggest a method to find all the VoIP devices in a network to monitor and manage them. I have searched the web for informations regarding this, but with very little success.
The only option that I have found is to discover a gatekeeper by sending a multicast message (gatekeeperRequest message) to 220.127.116.11. Is there similar ways for other devices like Call Server, IPPhone, Gateway, etc... Is there a way to get these information from the call server? At the moment, I am mainly focussing on Cisco devices. So, even a Cisco specific option would do.
Thanks & Regards, Stephen Regan.
