About 400 phones here at campus, another several hundred spread over WAN sites.

What is the size of your network?


I've had VoIP networks at different employers and with different vendors for 
over 6 years now, and as others have mentioned, what your vendor says is 
broadly accurate.


Welcome to the land of converged networks.


Part of the value of VoIP is that there is far less need for physical 
separation. The voice traffic and data traffic will be on different VLANs, but 
everything else can be combined.

Folks,
We are planning to retire our current phone system and move to a Mitel VOIP 
system. Not having implemented VOIP before, I have some questions for those of 
you that have:
- our vendor claims our current data network can easily handle VOIP traffic 
since it's a small amount of traffic (don't know exact amount yet, still 
awaiting vendor response). As such, they tell it is possible to use our current 
network to accommodate voice and data. I'm not sure if I"m comfortable with 
this. I was thinking of a more segregated approach: different network and voice 
and data never intersect. 
- our vendor claims we can use the existing data jack for the phones, and plug 
the desktop PCs/laptops into the phone as a sort of switch. I'm thinking this 
would add another level of complexity: phone is broke and by the way you can't 
get on the network now.
- the reason the vendor suggests the above is that the current voice drops 
(cat5) terminate to phone patch panels (in most cases). Those cables would need 
to be cut and re-terminated to switches. 
So I have some concerns about our vendor claims. The dollar figure they propose 
does not include network changes, new switches, etc. Looking at the cost 
proposal, I am thinking there are quite a few hardware and man-hours costs 
missing.
What do you folks do for VOIP?
Thanks,
Tom
