We are in the process of configuring voip at one of our locations.  The core switch is an HP A5500 EI and the switch that the phones will be plugged into is a HP Procurve 2530 POE Switch.  My biggest issue is the A5500 EI has different commands (believe 3com commands) than the procurve.  I'm not sure how I would configure the A5500 for voice as there will be no phones connected to it.  All of the vlans have been already created on the switches.  Any help would be greatly appreciated.

I think I need a little more information.  If the A5500 is just the core switch then I would assume you've seting up some trunking ports from the core to the 2530(s)?  WHat VLAN is the default vlan?  WHat vlan is the voice riding on ?  Make sure you tag that trunk port tothe 2530 and on the 2530 as tagged with all the vlans' you want to get to the core.  

Did you set up QoS tagging in the 2530?  Give me a show run please

Yes there is a trunk between the core and the 2530.  The default vlan is 1 and the voice vlan is 4.  All of the vlans I want are passing fine, I just didn't know how to configure voice similar to how you would on a procurve or if you would need to setup any sort of qos on the core since none of the phones are plugging into it.

I have ~ 40 sites with Procurve switches set up with Voice and data traffic and the only special thing I do is VLANing.  As that VLAN 4 makes its way to the layer 3 the priority (p&q) is assigned there upon ingress and egress.  

What do you program on your existing procurves now for Voice?  Are the VoiP phones not talking or having issues?

I set the vlan for voice and qos priority 6.  Not having any issues, I just want to make sure that the core has everything setup properly for voip as I'm not familiar with the HP 5500 series switches.

You really shouldnt have to do anything as the 5500 will just pass the 802.1pq tags as its forwarding the VoIP traffic.  As long as your vlan tags are on your uplinks in and out of the switch(es) you should be just fine.  If your VoIP traffic transitions to other subnets or through your MPLS at some point then the Routers do the heavy lifting.  Hope that helps
