Hello I am about to install VOIP in one of our offices my question is the internet connection comes in at the back of the building would it be wise to run coax threw the building to the server room or would it be ok to install the modem at the point of entry and run cat5 or cat6 threw the building to the server room? Will either make a difference or one better then the other ?

I'm confused. Modem? Are you talking about a cable modem?

If that is the case:
1) Make sure you know what your cap is and what happens when you go over
2) Make sure your modem is one step removed from your PBX

What are you using for a PBX? How are you doing VoIP? How many users? What do you currently have, cat5e or cat6? What about your switches/routers and NICs?

From what I know of your problem:
1) Put the modem at the coax drop
2) Use the Cat5e connection unless you have 1gb hardware
3) Make sure your PBX is one step from your modem

I do not think there is a substantive difference WRT cabling. However, I do believe there is an advantage of having the cable modem in the same location as the rest of your network components. quite often trouble with internet connections involve looking at both your local router and the cable modem to identify which is the culprit. much easier if they are both staring at you from the same shelf.
please rate my answer.
