Separate cabling is also useful if the phone system is being deployed by
a separate company - it avoids the 'your computer network is generating
rubbish traffic' arguments. (been there before, sadly)

I see a fair bit of separate physical networks because of different
management of phones vs IT. In the old businesses Facilities handles
the communications and IT is playing catchup all the time
So in these businesses where the IT side is swapping switches on a
weekly basis it is safer

I'm pretty sure they meant two logical networks. At least, I hope they did.
Unfortunately, I was indeed referring to two physical networks. Cabling,
switches, everything, all the way

Two separate networks? Did I miss something? I feel like I'm taking crazy
pills! Two separate physical networks means twice the hassle, twice the
maintenance, twice the cost, twice the headache. Not to mention the fact that
the whole idea of VOIP is to simplify IT and focus on converging data an
In my experience most of the serious QoS issues arise in relation to the
Internet pipe (if the provider is IP, and outside the network), not the
LAN. Of course, LANs can be heavily contended, but are not in most
organisations, especially as gigabit cores are getting increasingly
common even in

I'm wondering how prevalent the practice of physically segregating voice
and data networks is in the Real World.
What are the factors that typically lead to such a decision?
DIscussions of pros and cons are most welcome by me.
Experiences, anybody?
