Absolutely. That one surprised me also. :)

I'm not discounting that the connectivity comments arent good - but I was 
surprised to hear that a network connectivity drop/reset would trigger a PC 
reboot.  I want to take note of any phone that can cause that.

Melvin's comments are good ones. I do know that higher-end Cisco and PolyCom 
phones don't have those restrictions.

"phone reset" causes loss of network connectivity for the PC - this is because 
of a PORT reset on the switch. Make sure the port is specified as a client port 
("portfast" on Cisco) so that the port doesn't participate in STP calculations. 
At least, this was true in my experience, your mileage may vary.

Yes, it's possible.  I don't recommend it however.  There are a couple of 
common issues they will run into if they piggy back things.

When the phone resets (for any reason) you'll lose network connectivity on the 
PC.  In some cases we see it actually cause a PC reboot which I've yet to 
understand, but it can be reproduced.

On some (most?) phone sets, the network port is 100MB instead of GB, so you may 
end up restricting network throughput by doing this.  Some phones have GB 
ports, normally the higher end ones, and that will obviously be equipment 
specific, but it's something to watch for.

Hi all
i have a client that is setting up a new office with voip and naturally I'm 
recomending seperate drops and a seperate switch (small office < 30 users) 
,however , as most clients, they dont want spend anymore money than they have 
to, so they want to piggy back the computers to the phones ethernet port . Is 
it possible to vlan off the same drop/port ?
