Components of VoIP
Hello,
I am a network administrator with a little phone experience. My company will be moving into a new building within the next few months and we are starting from absolute scratch and leaving our entire existing infrastructure behind. It's a big job.
I would like to impliment an IP Phone system while we're at it. I have researched a number of sites on the internet but none seem to give me the summarization I am looking for to get started in putting the peices together.
Could someone here summarize a standard list of equipment that would be needed to impliment VoIP in a completely empty office with existing analog phone lines and CAT5?

oh, forgot to mention you also need fxs/fxo module to provide you analog signal unless you have bypass line from your telco.

Yikes! Well, I'm doing as much research as I can right now on VoIP. Quality is a big issue and you're the second person who has told me of initial issues with configuration. I take all matters to heart regarding this situation. I don't like making a bad name for myself so it sounds like I'd better have a backup plan.
Thanks for the kind words of advice.
It's worth the 50 pts. No other takers...

Clayperez,
I am currently using a system that has VoIp capabilities and I am running a remote office extension over a vpn that is maintained by linksys routers. I have been using it for a couple of weeks and for the most part the quality is suprisingly good (2 linksys routers and 2 cablemodems for the network connection) I have had some quality degredation but I think the Vox circuit on the speakerphones is too sensitive and that is what cuts things out. Whe We experience it it dissapears when we pick up the reciever and drop the speakerphone connection. The PBX can use any any analog phone so you can buy any cheapie phone and not have to fork out 100'$$$ for digital phones. I currently have 3 incoming analog lines but it can be provisioned with cards to handle pri/BRi and T1 connections. Obviously you have to have an IP phones if you are going to use VoIP. The bandwidth utilization is less than what is required to use RDP.
Let me ask you a couple of questions.
Are you trying to connect offices in different locations (Branch offices, remote teleworkers etc....)?
or are you just looking to use cat 5 for your phone lines?
If you dont need to connect branch offices then there is really no reason to use VoIP.
I hope this helps.

32 calls at 512K? 16k per call? Dont you think thats a Little Steep? Theres plenty of solutions out there using 8K per call? The equipment may be cheap but I would think the Infrastructure to support it could get as pricey as the Cisco solutions.
Just an observation

check out 3com.. the only disadvantage to using this system is that in order to have proper lighting on the phones (lines, ports, etc.) on remote sites, you need to have multicast VoIP routers. The 3com NBX series of routers are around 1300 a piece new. and the phone system w/ 10 phones and an NBX 100 (supports 200 devices on new firmware) and 4 port voice mail will be about $5,000 plus licensces/support/routers for remote sites.
I'm using a remote phone at home via cable over vpn (netgear fvs318 routers) with no degredation.
check it out, our company is very happy with our system, the ability to manage any phone from the pc at the desk your working at is a big plus, changing menus and users is a breeze, and the features that are standard such as COS control are unparrallel.
the only complaint that i have about the phones is the buttons for the main dial pad are a little doughy.. but other than that, great..
