Hey guys .. I Will try to make this short and sweet. At my job we are looking to implement a VOIP infrastructure. A typical infrastructure with voice and date usually will have both voice and data on a seperate VLAN.
Then a typical implementation is asking for trouble. The PC can flood 100Mb/s Ethernet, so it's possible for malcode on the PC to bring down that particular phone. IMO, that's a poor implementation.
A *good* infrastructure will have a seperate physical LAN segment for the phones (probably with PoE support.)
You might want to look at the recommendations in NIST's SP800 series that address VoIP. Doing VoIP right isn't as cheap as doing it poorly, but sooner or later if you lose voice and email at the same time, doing it right will be postively cheap.
