Layer 2 or layer 3 Switch

Looking to install a new switch needs to be a gigabit switch.  Looking to run VOIP on the network either use a mitel phone system or a avaya not weather to go for layer 3 or layer 2? Recommendations please and pros and cons of the two (layer 2or3 switch)

Anyday with your requirements I would suggest going for Layer 3 device so that you could eliminate the extra hop. With VoIP, you obviously want to do the vlans right? so do the routing in there as well - will be much faster and easy management.

I think it really comes down to whether or not you are using vlans and mixing with your other traffic.  VOIP is going to have to go out the router anyway.  You can save your internal traffic from hitting the router by implimenting a layer 3 switch which in turn will free up your router to process those VOIP pakcets quicker.  Layer 3 is king here, much more flexability, especially  if your not sure how you want to do it up front.

In what situation would you have layer 2 switch? does the extra Hop make that much of a difference (nano secs) as layer 2 is faster

It is not just about the speed in information transfer. It is about the number of hops and connections that you need to maintain and troubleshoot.

to add my two cents...
If you're running a setup where you will ONLY have voice on that switch, you can probably get by with an L2 switch.  If you're going to run either converged (voice and data across a single switchport) or mixed (voice on some switch ports and data on others) you'd be better served with an L3 switch so you can do proper VLAN tagging and inter-VLAN routing for proper QoS setup.

the other thing to watch for in a switch, particularly a gig switch, is PoE. If the IP phones have PoE and you want to make use of that, you're going to be stuck because the PoE switches are more expensive and typically have fewer gig ports (typicall for uplink or stacking ports only).
