Dear All,

I've got some chalenging questions about implementing Cisco VoIP and I looking for some fair answers:

6.What is the highest number of IP devices currently supported under a single instance of the software? How many IP devices are supported by a cluster?

7.Does the system have a web-based or GUI-based administration tool? Is this included in the base price?

8.Can a single administration portal/tool be used to manage all systems within an enterprise simultaneously? If not, explain the administrative process?

Re: VoIP chalenging questions


Sorry for the blast and for such VoIP questions. Due to the luck (tone's of material) of CISCO site and time constarin I was hoping that someone already knows the answers and is willing to share with the comunity w/o having to go to the pain and do a lot of search on CCO and hoping that you might find the fair answer for those questions.

Thanks a lot and have a good day!



Re: VoIP chalenging questions

Someone would spend a day typing everything up for you. If I were you, I would pick up a CallManager book. "Cisco IP Telphony: Planing, Design, Implentation, Operation and Optimization" There is also "Cisco CallManager Best Practice."

Or call your local Cisco Sales guy, they have local SE's that can give a briefing of the product in more details.

Most of know all the answers to those questions, but it would take any of us 2-3 hours to pull up. The books Cisco have out are great for reference and quick lookups for this stuff.

good luck!
